and it shows up as various modern diseases we experience today.</figcaption></figure></div><p><em><strong>For example:</strong></em></p><p><strong>Fat storage &#8594;</strong> The body accumulating toxins, deuterium, &amp; excess energy substrate your mitochondria can&#8217;t properly use.</p><p><strong>Balding &#8594;</strong> The body increasing skin surface in an attempt to maximize infrared &amp; UV light absorption from the sun. Balding is an oxidative stress problem at heart, and the mitochondria need IR and UV wavelengths to minimize electron leakage and stabilize ROS production. DHT increases locally to put out the oxidative fire.</p><p><strong>Hypothyroid &#8594;</strong> Suppressing thyroid hormone slows metabolism, mitigating excessive ROS and glycolysis from damaged mitochondria.</p><p><strong>Apnea &amp; poor breathing mechanics &#8594;</strong> Your body lowers oxygen intake because it&#8217;s under &#8220;pseudo-hypoxia,&#8221; where the mitochondria can&#8217;t properly take in and reduce oxygen to produce ATP and H2O. Adding more oxygen is like adding fuel to the fire (and why I hate the idea of CPAP machines).</p><p><strong>Sarcopenia &amp; anabolic resistance &#8594;</strong> If mitochondrial status is poor in the brain, heart, nervous system, and gonads, the body will keep excess energy liability (i.e. muscle) off the balance sheet, prioritizing the vital organs.</p><p><strong>Insulin resistance</strong> <strong>&#8594;</strong> A seasonal adaptation that increases fat storage in preparation for a scarce winter and raises blood glucose to keep the blood from freezing. It also keeps excess glucose from entering broken metabolic engines.</p><p><strong>Skin cancer &#8594;</strong> Concentrated melanin migrates to the skin surface to sop up as much UV light from the sun as possible to regulate bioenergetics and redox potential.</p><p><strong>Poor blood flow &#8594;</strong> The body accumulating excessive deuterium in the blood, keeping it away from the mitochondria and thickening the blood. Also buys time by slowing delivery of energy substrates, both oxygen and food, through the blood.</p><p></p><h3>Final thoughts</h3><p>There&#8217;s a reason people say almost all disease starts in the mitochondria. </p><p>Understanding dis-ease as a protective, adaptive mechanism increases awareness around our own biology. Instead of blindly administering some thyroid hormone or hair loss drugs, we can ask what our energy system really needs. It&#8217;s usually a combination of quantum inputs (light, grounding, magnetism), nutrients, and removing stressors, trigger foods, and other toxins.</p><p>It also shifts the unhealthy person from frustration to gratitude, which is healing in itself. When you&#8217;re sick or feel &#8220;broken,&#8221; remember your body is always working in your best interest. Treat it as your ally.</p><div class="captioned-image-container"><figure><a class="image-link image2 is-viewable-img" target="_blank"

absorbing all wavelengths of energy on the electromagnetic spectrum and transduces it into chemical energy that the body can use. This includes not only sunlight but also microwaves, radio frequencies, even gamma rays. <a href="https://pubmed.ncbi.nlm.nih.gov/28256187/">Melanin-rich fungi </a>have even been found in radioactive areas like Chernobyl because they use melanin to transduce EMF into usable energy for accelerated growth.</p></li><li><p><strong><a href="https://pubmed.ncbi.nlm.nih.gov/39794745/">Heavy metals</a>: </strong>Melanin is a powerful chelator of heavy metals, which are accumulated through daily exposure (tap water, vehicle exhaust, glyphosate, etc.).</p></li><li><p><strong>Gut pathogens</strong>: Melanin and its precursor, alpha-MSH, exhibit antimicrobial properties, neutralizing <a href="https://pubmed.ncbi.nlm.nih.gov/24934806/">candida</a>, <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC11354747/">bacteria</a>, and <a href="https://pubmed.ncbi.nlm.nih.gov/39794745/">mold</a> mycotoxins.

Melanin also uses absorbed light energy to liberate <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC11795818/">molecular hydrogen</a> from water molecules, reducing highly reactive hydroxyl radicals.</p></li><li><p><strong>Dopamine loss:</strong> Loss of melanin is implicated in <a href="https://pubmed.ncbi.nlm.nih.gov/37841274/">neurodegeneration</a>, likely because of its major energetic role in the brain and because of its regulation of dopamine (both melanin and dopamine come from the amino acid L-DOPA). <a href="https://movementdisorders.onlinelibrary.wiley.com/doi/10.1002/mds.29260">Melanin directly regulates dopaminergic neurons</a> in the brain.</p></li><li><p><strong><a href="https://pubmed.ncbi.nlm.nih.gov/26580677/">Deuterium build-up</a>:</strong> A few interesting mechanisms here. Melanin shows an <a href="https://x.com/jack_schroder_/status/1770467443623752024">affinity for deuterated &#8220;heavy water&#8221;</a> because D2O promotes better electrical conductivity in melanin than H2O.

Cold dopes all semiconductors in the body, including melanin (eskimos are tan for a reason).<strong> </strong></p></li><li><p><strong>Melanogenesis nutrition</strong>: Melanin production requires animal protein, vitamin C, iron, copper, zinc &amp; B Vitamins (indirectly for BH4 production).</p></li><li><p><strong>Support dopamine: </strong>Stop doomscrolling, minimize screens, lower

Weight has been maintained around 185 in the two months after.</figcaption></figure></div><p>I love the idea of skipping dinner for three reasons:</p><ol><li><p><strong>Pre-commitment: </strong>For the average person, afternoon and evening time is a nutrition DANGER ZONE &#8212; mindless snacking, binging at dinner due to poor caloric intake earlier in the day, eating too late which interferes with digestion and sleep, late-night desserts and/or nightcaps, etc. Saying no to that entire window makes things easier.</p></li><li><p><strong>Practicality: </strong>A few friends/family have taken interest in the protocol because they&#8217;re so busy in the evenings. Rather than scarfing down a 9pm dinner then trying to get to sleep, it&#8217;s much more realistic to skip it altogether in favor of a bigger breakfast and lunch.</p></li><li><p><strong>Mortification: </strong>The culture HATES discomfort, but suffering is redemptive. Jesus tells us to pick up our cross and follow Him. Paul tells us to deny the flesh and live by the Spirit. Not just to glorify God but to experience fullness of life. Skipping dinner is hard, and it&#8217;s a small way to step into suffering, offer it up for grace, and prepare yourself to endure much greater adversity that comes later.</p></li></ol><p>Skipping dinner is especially impactful to run in the winter due to:</p><ul><li><p><strong>Shortened light cycles &amp; food scarcity: </strong>In nature, there&#8217;s less sunlight and food availability in the winter. Metabolism naturally moves into repair and maintenance with less energy to harness from the environment. Skipping dinner here provides a coherent winter-time signal.</p></li><li><p>Most likely coming off of <strong>excessive processed food intake, drinking, etc. from during the holidays</strong></p></li></ul><div class="captioned-image-container"><figure><a class="image-link image2 is-viewable-img" target="_blank"

bodyweight</strong>. This ended up being ~130g for me. I didn&#8217;t always hit this, especially towards the end, which likely contributed to things tipping slightly catabolic.</p></li><li><p><strong>Carbs:</strong> Start with <strong>100-150g</strong> spread evenly across breakfast and lunch. Include a mix of starches (potatoes, white rice, oats, sourdough) and berries/honey. Starches at lunch will be more satiating due to higher content of fiber and lower glycemic (blood sugar) load.</p></li><li><p><strong>Fats:</strong> Start with <strong>60-90g</strong> spread evenly. Coconut/MCT oil, avocado, egg yolks, fattier meats, raw nuts/seeds, fatty fish, olive oil, beef tallow... </p></li><li><p>Use this <a href="https://www.calculator.net/calorie-calculator.html">calculator </a>as a simple starting point for total daily caloric intake. Start with the maintenance or mild weight loss number.</p></li><li><p>Eventually, make your breakfast high-carb and lunch high-fat for enhanced metabolic flexibility (discussed more below).</p></li><li><p>Sample breakdowns for me:</p><ul><li><p><strong>Break (795 cal):</strong> 65g protein, 100g carbs, 15g fat</p></li><li><p><strong>Lunch (965 cal):</strong> 65g protein, 30g carbs, 65g fat</p></li><li><p><strong>1,760 cal total </strong>- this is around a 500-calorie deficit at my normal activity level, hence why I&#8217;m recommending 30-60 day max on this</p></li></ul></li></ol></li><li><p>Weekly Adjustments</p><ol><li><p><strong>3-5 days prior:</strong> Track your typical breakfast &amp; lunch in the Cronometer app, determine adjustments to calorie/macro intake and nutrients so you don&#8217;t run into major deficiencies.</p></li><li><p><strong>Week 1:</strong> Reduced physical activity &amp; training volume, just focusing on eating window and light movement such as mobility and walking.</p></li><li><p><strong>Week 2:</strong> Increased activity &#8212; 8-10k steps post-meal, 3-4 low volume strength sessions.

This became more problematic later on as adherence &amp; preparation started to dwindle. </p><p>The end result is excess catabolism (muscle loss), but you can get around this by ensuring you&#8217;re hitting daily protein, increasing macro targets if you&#8217;re training more, adding a quality mineral source to water (Trace, Quinton, BEAM, Shilajit&#8230;) and ensuring a diverse array of fruits and vegetables with each meal. </p><p>Other forms of metabolic stress include cheat meals, avoiding nature, moving too much or too little, sunlight deficiency (use a light device if you need to), relationships, blue light at night, career, and getting overly neurotic about doing everything perfectly&#8230;take extra care to off-load stress during this time.</p><p>Most importantly, you need to get your circadian rhythm as dialed as possible to reap the full benefit of the protocol. </p><p>An earlier eating window works because it aligns with the circadian clock. You need to get sunlight on eyes and as much skin as possible first thing AM and as much as possible during the day. Use <a href="https://healthlighting.com/">incandescents</a> or lizard lamps indoors during the day and block blue light at night with lighting, long sleeves, and/or <a href="https://midwestredlighttherapy.com/product-category/blue-light-blocking-glasses/">glasses</a>.</p><p><strong>What to expect</strong></p><p>You&#8217;ll probably notice a steep drop in weight the first 1-2 days. This will also happen if you make the shift to high-fat low-carb lunches.</p><p>Your body is shedding water, which is bound to the stored glycogen in your muscle and liver. During calorie/carb restriction, the glycogen is liberated as well as the water. Consistent fat loss will continue over the 30 days.</p><p>Sleep quality will also probably suffer at the onset. I struggled to get to sleep and had 2-3 nighttime wake-ups in the first three days before my body adjusted.</p><p>Your hunger is going to be ripping on the first one or two evenings. Fill up on non-caloric fluids, especially sparkling mineral water and herbal tea.</p><p>Lastly, I was pleasantly surprised by the improvement in GI-related symptoms. White coating on tongue, bloating, and skin irritation all decreased. By eating less often, you offer more time for regeneration of the gut lining while eliminating potential trigger foods that feed overgrowths.</p><p>When reintroducing dinner, opt for a soup with a bone broth base, loaded with vegetables and some protein. Start small and titrate up to a normal-sized dinner over 3-5 days (<a href="https://40aprons.com/tom-kha-soup-whole30/#wprm-recipe-container-15842">chicken tom kha gai</a> was my go-to here).</p><p><strong>Advanced Modifications</strong></p><ul><li><p><em><strong>Randle Cycle:</strong></em> If you choose to separate macros in weeks 3 &amp; 4 as described above, you&#8217;re taking advantage of the Randle cycle. Essentially, it states that carbs and fats compete for metabolism, and the more you can keep them separate, the more efficiently your body will produce energy and minimize fat storage and ROS. Since insulin sensitivity is highest in the AM, breakfast would be the time for higher carb intake. Higher fat at lunch allows the body to enter ketosis more easily overnight. My AM ketone levels shot up significantly when eating this way.</p></li></ul><ul><li><p><em><strong>UVB Light Therapy:</strong></em><strong> </strong>Supplementing with UVB light adds another layer of metabolic stimulus, mainly through UVB&#8217;s effect on producing alpha-MSH, which increases metabolic rate while lowering appetite. Use a <a href="https://healthlighting.com/collections/full-spectrum-reptile-and-bird-lighting/products/chromalux-high-power-reptile-uv-bulb">lizard lamp</a> throughout the day or a PBM device such as <a href="https://emr-tek.com/products/krypton-micro?gad_source=1&amp;gad_campaignid=22285474034&amp;gbraid=0AAAAADBKWIUpD36IVu-F26sutFdrALpYe&amp;gclid=Cj0KCQjwqPLOBhCiARIsAKRMPZrKdagH9ge-nn6jBRN-FJXl0ZPvRX4wObl-vRWkZGy5CdxMGxz0vM4aAsh8EALw_wcB">this one</a>. </p></li><li><p><em><strong>Cold Exposure:</strong></em> The body is used to experiencing food scarcity and cold temperatures at the same time (how winter was designed). <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9273773/">Stacking cold increases metabolic rate and lowers ROS by increasing thermogenesis in fat tissue</a>. Go for 2-5 minutes in cold water or a longer walk in the ambient cold with minimal layers. Never do it in a fasted state, and be careful not to go overboard as to not add deleterious stress to the system.</p></li><li><p><em><strong>Increase Water Intake:</strong></em> <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2827021">Increasing daily water consumption seems to help with weight loss</a>. It also acts as a vehicle for essential minerals when you add them into your water.</p></li><li><p><em><strong>Supplementation: </strong></em>The metabolic supplements listed above can assist in glucose and fat metabolism. 5g of creatine and 1-2 servings of essential amino acids can offer additional support in staving off muscle loss. Vitamin E and choline can dampen inflammation from fat loss and support bile flow. Layer in gut support as desired &#8212; black seed oil, curcumin, NAC, aloe juice, L-Glutamine, binders&#8230;(requires additional context).</p></li></ul><h3>Final Thoughts</h3><p>This is a fun challenge to run anytime of year, but especially during the winter when your body is expecting a period of energy scarcity.</p><p>The goal is improved metabolic health, which I certainly achieved, and weight loss is a natural consequence.</p><p>Although it&#8217;s hard, treat the 30 days as a time of regeneration. Slow things down, stay disciplined and try not to fall off towards the end as motivation fades. You&#8217;ll be proud of the results.</p>]]></content:encoded></item><item><title><![CDATA[Sunlight is Muscle-Sparing.]]></title><description><![CDATA[The modern athlete, whether performance- or

While artificial blue light in isolation is harmful, blue light in the context of the sun&#8217;s full spectrum increases sympathetic drive, dopamine, and circulating blood sugar and catecholamines, all of which are crucial signals for maximal physical output during training.</p><p>Within the ultraviolet spectrum is <strong>UVA and UVB light. </strong>UVA exposure enhances dopamine through the <a href="https://www.harrisonbach.com/p/the-dopamine-restoration-protocol">photo-excitation of tyrosine</a>. But perhaps UVA light&#8217;s most important role for muscle is <a href="https://pubmed.ncbi.nlm.nih.gov/24924758/#:~:text=Abstract,additional%20effects%20on%20human%20health.">increasing blood flow</a>. </p><p>UVA exposure drives the release of nitric oxide from skin cells. <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9921013/">Nitric oxide is a known performance enhancer</a>. Enhanced blood flow means more oxygen and energy substrates carried to the muscle and nervous system. You&#8217;ll be hard-pressed to fine a gains-maxxer that&#8217;s not using some sort of NO enhancer. UVA does it for free. </p><p>UVB light is just as impressive. Vitamin D, synthesized in response to UVB on the skin, <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC11279438/">enhances muscle function by reducing oxidative stress in muscle tissue</a>. </p><p>UVB also <a href="https://www.harrisonbach.com/p/uvb-light-is-a-performance-enhancing">interacts with the POMC molecule </a>to produce a pharmacy of performance-enhancing peptides. These include:</p><ul><li><p><strong>Alpha-MSH: </strong><a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5034615/">a-MSH increases glucose uptake in muscle.</a> It&#8217;s been shown to <a href="https://journals.physiology.org/doi/full/10.1152/ajpregu.00447.2012">directly decrease muscle wasting </a>when administered to older populations. Alpha-MSH is a truly insane molecule for physique&#8230;it reduces appetite, increases energy expenditure, and preserves muscle all at the same time.

Use <a href="https://mycircadianapp.com/">MyCircadian</a> to check for your location.</p><h3>DON&#8217;T FORGET DARKNESS AT NIGHT!</h3><p>Sunlight is only effective in the circadian context, which means bright sunlight during the day and near-total darkness at night.</p><p><a href="https://pubmed.ncbi.nlm.nih.gov/30528733/">Constant light exposure into night hours speeds up muscle wasting</a>. Artificial light at night (ALAN) modulates the POMC molecule to increase catecholamines and blood glucose around the clock, a constant metabolic stress that contributes diminished muscle mass and function.</p><p>Even a small amount of ALAN suppresses melatonin and affects POMC.

But if you live in the gym, you&#8217;re missing out on gains if you&#8217;re not balancing out training time with sun time. Make sure you&#8217;re getting sufficient exposure in the key windows:</p><ul><li><p>Sunrise and sunset are free red-light therapy. UV isn&#8217;t available during this time.</p></li><li><p>UVA enters 60-90 minutes after sunrise and leaves 60-90 minutes before sunset. </p></li><li><p>UVB depends on your season and location, typically strongest from 10a-2p. UVB is unavailable in northern latitudes in the winter.</p></li></ul><p>The sunlight rabbit hole led me to move virtually all of my training to an outdoor setting. Of course, you&#8217;re sacrificing some gains with this approach, but it&#8217;s generally been easy for me to achieve strength and hypertrophy gains despite a minimalist approach that&#8217;s largely calisthenics-driven.</p><div class="captioned-image-container"><figure><a class="image-link image2 is-viewable-img" target="_blank"

shown <a href="https://pubmed.ncbi.nlm.nih.gov/31918985/">skipping breakfast long-term is associated weight gain and obesity</a>.</p><p>I&#8217;ve personally spoken to and worked with a handful of men who got into fasting because it helped them lose weight, but eventually their progress stalled out and left them skinny fat.</p><p>So why would skipping dinner be any better?</p><h4>Circadian Alignment</h4><p><a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4089089/">Metabolism is dictated by the circadian rhythm</a>. The body is primed to digest and metabolize food when the sun is out, aka earlier in the day. An earlier eating window aligned with the circadian clock <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC10528427/">improves glucose metabolism, fat oxidation, hormonal profile, and sleep quality</a>.</p><p>The standard 12:00-8:00 eating window touted by OG intermittent fasters is simply too late in the day. Even Jason Fung, the so-called godfather of intermittent fasting, says you need to eat earlier.</p><div class="captioned-image-container"><figure><a class="image-link image2 is-viewable-img"

burn vs. storage. Leptin tells the brain how much energy is available via fat stores or in circulation. </p><p>Skipping breakfast suppresses leptin, triggering a metabolic cascade that <em>increases appetite and reduces energy expenditure</em> (i.e. increased fat storage). Your brain thinks you&#8217;re starving, so it shifts into food-seeking and fat-storage mode.</p><p>Conversely, <strong>an earlier breakfast signals abundance and safety</strong>. An early pulse of leptin = &#8220;we have plenty of energy on hand, so eat less and make more energy.&#8221; Appetite is regulated while resting metabolic rate improves.</p><p><em>Side note</em>: leptin is a circadian hormone, so sunlight during the day + darkness at night is crucial for its function. Midday sun is also critical to drive leptin&#8217;s metabolic activity through alpha-MSH and the leptin-melanocortin pathway.</p><div class="captioned-image-container"><figure><a class="image-link image2 is-viewable-img" target="_blank" href="https://substackcdn.com/image/fetch/$s_!qpUM!,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F5d6c1a44-a6a0-4728-90fa-5394157729f5_800x1021.jpeg" data-component-name="Image2ToDOM"><div class="image2-inset"><picture><source type="image/webp" srcset="https://substackcdn.com/image/fetch/$s_!qpUM!,w_424,c_limit,f_webp,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F5d6c1a44-a6a0-4728-90fa-5394157729f5_800x1021.jpeg 424w, https://substackcdn.com/image/fetch/$s_!qpUM!,w_848,c_limit,f_webp,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F5d6c1a44-a6a0-4728-90fa-5394157729f5_800x1021.jpeg 848w, https://substackcdn.com/image/fetch/$s_!qpUM!,w_1272,c_limit,f_webp,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F5d6c1a44-a6a0-4728-90fa-5394157729f5_800x1021.jpeg 1272w, https://substackcdn.com/image/fetch/$s_!qpUM!,w_1456,c_limit,f_webp,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F5d6c1a44-a6a0-4728-90fa-5394157729f5_800x1021.jpeg 1456w" sizes="100vw"><img src="https://substackcdn.com/image/fetch/$s_!qpUM!,w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F5d6c1a44-a6a0-4728-90fa-5394157729f5_800x1021.jpeg" width="800" height="1021" data-attrs="{&quot;src&quot;:&quot;https://substack-post-media.s3.amazonaws.com/public/images/5d6c1a44-a6a0-4728-90fa-5394157729f5_800x1021.jpeg&quot;,&quot;srcNoWatermark&quot;:null,&quot;fullscreen&quot;:null,&quot;imageSize&quot;:null,&quot;height&quot;:1021,&quot;width&quot;:800,&quot;resizeWidth&quot;:null,&quot;bytes&quot;:77819,&quot;alt&quot;:null,&quot;title&quot;:null,&quot;type&quot;:&quot;image/jpeg&quot;,&quot;href&quot;:null,&quot;belowTheFold&quot;:true,&quot;topImage&quot;:false,&quot;internalRedirect&quot;:&quot;https://www.harrisonbach.com/i/184332515?img=https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F5d6c1a44-a6a0-4728-90fa-5394157729f5_800x1021.jpeg&quot;,&quot;isProcessing&quot;:false,&quot;align&quot;:null,&quot;offset&quot;:false}" class="sizing-normal" alt="" srcset="https://substackcdn.com/image/fetch/$s_!qpUM!,w_424,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F5d6c1a44-a6a0-4728-90fa-5394157729f5_800x1021.jpeg 424w, https://substackcdn.com/image/fetch/$s_!qpUM!,w_848,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F5d6c1a44-a6a0-4728-90fa-5394157729f5_800x1021.jpeg 848w, https://substackcdn.com/image/fetch/$s_!qpUM!,w_1272,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F5d6c1a44-a6a0-4728-90fa-5394157729f5_800x1021.jpeg 1272w, https://substackcdn.com/image/fetch/$s_!qpUM!,w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F5d6c1a44-a6a0-4728-90fa-5394157729f5_800x1021.jpeg 1456w" sizes="100vw" loading="lazy"></picture><div class="image-link-expand"><div class="pencraft pc-display-flex pc-gap-8 pc-reset"><button tabindex="0" type="button" class="pencraft pc-reset pencraft icon-container restack-image"><svg role="img" width="20" height="20" viewBox="0 0 20 20" fill="none" stroke-width="1.5" stroke="var(--color-fg-primary)" stroke-linecap="round" stroke-linejoin="round" xmlns="http://www.w3.org/2000/svg"><g><title></title><path d="M2.53001 7.81595C3.49179 4.73911 6.43281 2.5 9.91173 2.5C13.1684 2.5 15.9537 4.46214 17.0852 7.23684L17.6179 8.67647M17.6179 8.67647L18.5002 4.26471M17.6179 8.67647L13.6473 6.91176M17.4995 12.1841C16.5378 15.2609 13.5967 17.5 10.1178 17.5C6.86118 17.5 4.07589 15.5379 2.94432 12.7632L2.41165 11.3235M2.41165 11.3235L1.5293 15.7353M2.41165 11.3235L6.38224 13.0882"></path></g></svg></button><button tabindex="0" type="button" class="pencraft pc-reset pencraft icon-container view-image"><svg xmlns="http://www.w3.org/2000/svg" width="20" height="20" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round" class="lucide lucide-maximize2 lucide-maximize-2"><polyline points="15 3 21 3 21 9"></polyline><polyline points="9 21 3 21 3 15"></polyline><line x1="21" x2="14" y1="3" y2="10"></line><line x1="3" x2="10" y1="21" y2="14"></line></svg></button></div></div></div></a><figcaption class="image-caption">Leptin controls metabolic rate and appetite signaling.

sex hormone formation in favor of cortisol production.</figcaption></figure></div><p>Chronically activated ACTH and CLIP leads to metabolic disarray long-term, contributing to fat storage, insulin resistance, and mitochondrial dysfunction. In this sense, UVB is also indirectly protective of metabolic health.</p><p></p><h3>More Benefits of UVB</h3><p><strong>Gut &amp; Immune Modulation:</strong> UVB drives the conversion of 7-dehydrocholesterol into Vitamin D, <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7322162/">healing the gut lining</a> and optimizing <a href="https://www.frontiersin.org/journals/immunology/articles/10.3389/fimmu.2023.950465/full">white blood cell activity</a>. UVB exposure has also been shown to positively modulate the <a href="https://pubmed.ncbi.nlm.nih.gov/31708890/">microbiome</a>.</p><p><strong>Regulates cholesterol: </strong>UVB ensures cholesterol is properly funneled into Vitamin D and sex hormone synthesis</p><p><strong>Mood &amp; Sleep: </strong>The amino acid tryptophan strongly absorbs UVB light with an absorption peak of 280nm. Tryptophan is the precursor for serotonin and melatonin, boosting mood and supporting sleep quality (provided you&#8217;re nighttime environment is as dark as possible).</p><p><strong>Dopamine &amp; Thyroid: </strong>Tyrosine, another aromatic amino acid, also absorbs UVB light (less strongly than tryptophan). Tyrosine is the precursor for molecules such as dopamine, thyroid hormone, noradrenaline, and melanin. Dopamine supports motivation, coordination, delayed gratification, and executive function while thyroid hormone is essential for metabolic health, regulating fat storage and energy production.</p><p></p><h3><strong>Tools to Optimize UVB Light Exposure</strong></h3><p>Hopefully it&#8217;s clear you need more UVB, even if you&#8217;re not chronically ill or focused on longevity. Obviously the most effective way to get it is through sunlight. If you live in a tropical area (sub-20 latitude) or a place like Florida, you can get UVB year-round. Use the <a href="https://mycircadianapp.com/">MyCircadian app</a> to find your exact window of exposure based on where you live and time of year. Prioritize sunlight first and foremost, maxing out during the summer months.</p><p>If you live in a cold winter latitude like Chicago or work a desk job and can&#8217;t get outside consistently, use the tools below to supplement UVB. Be careful to avoid burning and prioritize circadian health no matter what. Ensure adequate red and infrared light exposure throughout the day and before/during/after UVB sessions. Do your sessions on your lunch break or between hours of 10a-2p.</p><div class="captioned-image-container"><figure><a class="image-link image2 is-viewable-img" target="_blank"

Left side was a strict cyclical keto diet, the &#8220;gold standard&#8221; at the time. Right side is high carb, low fat, low-moderate protein, which showed improvements across the board (RHR, HRV, body temp&#8230;)</figcaption></figure></div><h4>Set-Up</h4><p><strong>One change at a time: </strong>If you&#8217;re manipulating multiple variables at once, there&#8217;s no way to tell what&#8217;s helping and what&#8217;s hurting. Focus on one variable at a time and keep every other element of your lifestyle as consistent as possible.</p><p><strong>Form a hypothesis, but stay objective: </strong>There should be some intention behind what you&#8217;re trying rather than &#8220;I&#8217;m just doing it to see what happens.&#8221; You should also be prepared and open-minded to a result you&#8217;re not expecting. Your n=1 will often be vastly different than someone else&#8217;s.</p><p><strong>Long enough timeframe: </strong>The body often changes slowly. I&#8217;ll be running 30-day experiments but the truth is you may need a longer timeframe of 2-3 months before you start seeing anything meaningful in the data. Don&#8217;t stop too soon before the magics starts to happen.</p><p><strong>Plan ahead: </strong>Make sure life doesn&#8217;t get in the way ahead of time. Maybe that means meal prepping, communicating with loved ones, making sure supplements are ordered, etc.</p><p><strong>Follow through: </strong>This ties in with the long timeframe. If you&#8217;re making meaningful changes, it&#8217;ll probably feel uncomfortable at times. Stay the course and log whatever you&#8217;re feeling as a datapoint. Ex: &#8220;Really strong cravings for sweets on day 7&#8221; </p><p></p><h4>Tracking</h4><p>Tracking your data is the key to stopping the guesswork and getting objective conclusions from your experiments. Ideally, you&#8217;re tracking over various time horizons:</p><p><strong>Real-time tracking with wearables: </strong>Oura and WHOOP are helpful for metrics like HRV, resting heart rate, sleep quality, and menstrual cycle. A CGM offers insight into real-time blood glucose response from specific lifestyle interventions (food types, meal/exercise timing, sunlight exposure, etc.).</p><p><strong>Daily/Intra-daily tracking: </strong>Use a KetoMojo to test glucose and ketone levels strategically throughout the day (ex: first thing after waking, one hour after eating). Chris Masterjohn also advocates tracking lactate for additional metabolic health insights, though this is more expensive. It&#8217;s also worthwhile to log daily food intake in Cronometer to ensure you&#8217;re staying consistent and/or hitting the desired macros and nutrient intake.</p><p><strong>Longer-term tracking: </strong>Get labs done to assess progress over a longer time horizon (1+ month). Bloodwork is most common and cost-friendly, but you may also choose a GI map, organic acids test, or hair tissue mineral analysis depending on the desired metrics and outcomes. Use <a href="https://ownyourlabs.com/">Own Your Labs</a> if you&#8217;re looking for specific blood tests or a service like <a href="https://www.functionhealth.com/">Function </a>for comprehensive year-long testing.</p><p><strong>Qualitative tracking: </strong>I highly recommend journaling daily to log subjective effects of the interventions you&#8217;re running. This will add color to all the quantitative metrics you&#8217;re tracking and really start to build body awareness. Timestamp what day/time you&#8217;re on and whatever emotions, physical sensations (pain, drowsiness, etc.), cravings, thoughts, and anything else meaningful that arises.</p><p></p><h4>My 2026 Self-Experiment Lineup</h4><p>Now that you have the framework, here are some n=1&#8217;s I plan on running on myself in 2026. The timeframe for most of these will be 30 days with before/after bloodwork based on the intervention and finances. May also dust off the old Oura ring if it&#8217;s still functional. </p><ul><li><p>Skipping dinner (starting next week)</p></li><li><p>Nutrient maxing - thiamine, magnesium, potassium,

compound.</strong></p><p>This is something my friend Jack Schroder has mentioned in his community and I&#8217;ve found it works really well at optimizing neurochemistry for deeper work and easier access to flow state. You can certainly get more advanced than this, but I&#8217;ve found this framework keeps things simple while still being very effective in enhancing my mental capacity.</p><p><strong>Why it works:</strong></p><p><em>Dopamine</em> engages motivation, pursuit, and pleasure with completing tasks. You need to be engaged with your work to enter flow, and that relies on healthy dopamine signaling.</p><p><em>Acetylcholine</em> sharpens mental acuity, increasing focus, detail orientation, and precision. It&#8217;s what helps you think clearly and sharpens your actual performance in said task.</p><p>Lastly, <em>GABA</em> smooths out the mental stimulation with mild inhibitory effects. <strong>It helps you work like a lion, not a squirrel.</strong></p><p>The combination of the three result in deep, sharp, yet calm focus. The perfect mental state for getting sh*t done.</p><p><a href="https://www.harrisonbach.com/p/the-ultimate-productivity-protocol">The productivity protocol</a> lays out a long list of compounds you can use and the mechanisms they target (ex: increasing synthesis vs. inhibiting breakdown vs. improving receptor density/sensitivity&#8230;). Use that list to experiment with your own blends and ratios.</p><p>In the meantime, here are the three stacks that I use to reliably supercharge my productivity:</p><p></p><ol><li><p><em>Coffee (1c) + Alpha GPC (600mg) + L-Theanine (200mg)</em></p></li></ol><p><strong>Warning</strong>: this one will rocket you violently into flow state. Coffee is both a MAO inhibitor and an adenosine antagonist, slowing dopamine breakdown while increasing release. Alpha GPC easily crosses the blood brain barrier where it donates choline for acetylcholine synthesis. Lastly, L-Theanine is a GABAa agonist, offering slight inhibitory effects to prevent jitters and scatter brain.</p><p></p><ol start="2"><li><p><em>Oolong + Sencha Green + Gingko Biloba + Gotu Kola</em></p></li></ol><p>Oolong and sencha green tea are dopaminergic, increasing dopamine release directly while disinhibiting dopamine via adenosine antagonism. They also inhibit MAO, though more mildly than coffee, and contain trace amounts of L-Theanine for mild inhibitory effects. Gingko biloba is a ChAT modulator, enhancing acetylcholine synthesis and release. Lastly, gotu kola demonstrates both cholinergic and GABAergic effects, increasing ChAT activity, protecting cholinergic neurons, and mildly inhibiting AChE to slow ACh breakdown. It also directly enhances GABA levels as a positive allosteric modulator of GABAa.</p><p>I combine these in loose leaf form with <strong>1 part oolong, 1 part sencha, 1 part gingko, and 0.5 part gotu kola. </strong>Steeping 2 tsp at a time yields the greatest benefits.</p><p></p><ol start="3"><li><p><em>Troscriptions Blue Cannatine</em></p></li></ol><p>The <a href="https://troscriptions.com/products/bluecannatine?srsltid=AfmBOopDu0eFH3JB0EV4RDqrCXF6_aS3MNiTva4cxVR6oHQDB0imjOQw">Blue Cannatine</a> product by Troscriptions contains caffeine, nicotine (strong dopaminergic and cholinergic), methylene blue (MAO inhibitor &amp; mitochondrial upregulator), and CBD (GABAergic). It&#8217;s a nice formulation for smooth sustained focus with buccal (cheek) delivery for better absorption. In my experience, the effects are much more mild than the first two but still noticeable. I use this much less frequently.</p><p></p><p>It&#8217;s important not to over-rely on nootropic compounds and blends so your neurochemistry doesn&#8217;t become desensitized to the effects. I use the first two stacks 1-3 times per week and Blue Cannatine maybe once a month. If you have a known issue with neurotransmitter balance (i.e ADHD, history of SSRIs, low dopamine), it&#8217;s best to avoid altogether. </p><p>Build up a solid foundation and system for focus (use the <a href="https://www.harrisonbach.com/p/the-ultimate-productivity-protocol">productivity protocol</a>) first, then add these to take it to the next level.</p><p>Godspeed!</p>]]></content:encoded></item><item><title><![CDATA[The Ultimate Productivity Protocol]]></title><description><![CDATA[How to get more done in the modern world.]]></description><link>https://www.harrisonbach.com/p/the-ultimate-productivity-protocol</link><guid isPermaLink="false">https://www.harrisonbach.com/p/the-ultimate-productivity-protocol</guid><dc:creator><![CDATA[Harrison Bach]]></dc:creator><pubDate>Thu, 11 Dec 2025 17:26:51 GMT</pubDate><enclosure url="https://substackcdn.com/image/fetch/$s_!Mf_H!,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F775f943a-affa-4ac4-98f2-3d229e82ab58_491x336.jpeg" length="0" type="image/jpeg"/><content:encoded><![CDATA[<p>Modern man has forgotten what true productivity is like. Deep focus and output should be the baseline, but today we&#8217;re more distracted than ever and our physiology is depleted to the point that even simple work feels like a struggle.</p><p>Elite productivity takes intention in the modern world. If you want to get an insane amount of work done in less time and with less challenge, it comes down to <strong>four pillars</strong>: <strong>health, environment, focus, and process</strong>.</p><p></p><p><strong>Good Health Lays the Foundation</strong></p><blockquote><p>&#8220;&#8230;to perform your best&#8230;and truly reach and sustain your performance potential, you need to be a healthy person first.&#8221; - <em>Peak, </em>Dr. Marc Bubbs</p></blockquote><p>A solid foundation of health is required for any performance discipline, especially focus, creativity, and productivity. You can&#8217;t put out your best work if your physiology leaves you foggy and low energy. Make sure you&#8217;re consistently dialing in the health fundamentals:</p><ul><li><p><strong>Sleep quality: </strong>non-negotiable for daytime output and alertness</p></li><li><p><strong>Circadian rhythm: </strong>alertness and energy production during the day and restoration at night</p></li><li><p><strong>Nature: </strong>mitigates mental fatigue, stress accumulation, and mitochondrial function</p></li><li><p><strong>Blood sugar: </strong>spikes and crashes cause brain fog and lapses in focus</p></li><li><p><strong>Gut health:</strong> Pathogenic overgrowth drives neuroinflammation, brain fog, and energy lapses</p></li><li><p><strong>Stress management:</strong> Keeping the nervous system regulated and building resilience is essential for getting work done</p></li><li><p><strong>EMF mitigation:</strong> Reduce exposure where possible, especially in your work space and while you sleep</p></li><li><p><strong>Oxygen delivery:</strong> Posture, mobility, breathwork, and sunlight/grounding are essential for delivery and utilization of oxygen in the mitochondria</p></li></ul><p></p><p><strong>Work Environment Optimization</strong></p><p>Your workspace either enables focus or destroys it. The standard office cubicle is a classic example of how <em>not</em> to design your workspace for productivity. No access to the outdoors or windows. Flickering blue-dominant lighting overhead. Ambient noise and impromptu &#8220;pop-ins&#8221;&#8230;</p><p>The most ideal work setup would be outdoors in a relatively secluded area. The direct &amp; indirect sunlight, brightness, fresh air, and grounding set the physiology for optimal productivity without burning out the system.</p><p>Now, obviously that&#8217;s not practical for most, but use that as a framework to strive for with your indoor workspace:</p><ul><li><p><strong>Optimize lighting</strong> using a <a href="https://getchroma.co/products/sky-portal?srsltid=AfmBOooF4yYnoTQPDqEfbJItfQYAsU6yAgZSPLB6dMiCoLPo-Wep1kMm">Chroma Sky Portal</a> for brightness and <a href="https://niralighting.com/">NIRA</a> or <a href="https://strainlesslighting.com/">incandescent</a> light bulbs for infrared light, reducing sympathetic load from flicker, and supporting retinal health</p></li><li><p>A <a href="https://healthlighting.com/collections/full-spectrum-reptile-and-bird-lighting/products/chromalux-high-power-reptile-uv-bulb">reptile bulb</a> can be used periodically to <strong>supplement UV light</strong> while you&#8217;re working</p></li><li><p>Use <a href="https://iristech.co/">Iris</a> software on your screens to <strong>minimize the blue light spike and open windows</strong> whenever possible to balance out the spectrum and get fresh air</p></li><li><p>A <strong><a href="https://intuition-physician.myshopify.com/products/organic-grounding-mat-soft-and-eco-friendly-grounding">grounding mat</a></strong>, ideally plugged directly into the earth and fed through a window, reduces neuroinflammation and increases energy output in the brain while working</p></li><li><p>Prioritize <strong>getting outside</strong> and <strong>moving your body on your breaks</strong></p></li></ul><div class="captioned-image-container"><figure><a class="image-link image2 is-viewable-img" target="_blank"

the room, silence notifications on your computer, and use noise-cancelling corded headphones and daytime blue light blockers if necessary</p></li><li><p><strong>Declutter:</strong> a clean workspace reduces cognitive load and distractibility</p></li></ul><p></p><p><strong>Workflow Planning &amp; Process</strong></p><p>Productivity is as much about efficient work as it is about hard work. You need a consistent, clearly defined process for how you&#8217;re going to get sh*t done amidst a busy lifestyle and competing interests.</p><ul><li><p><strong>Set long-term goals: </strong>what do you want to achieve three years from today?</p></li><li><p><strong>Break down the time horizon:</strong> You have your three-year target. Where do you need to be in one year, six months, three months, one month, one week from now to stay on track?</p></li><li><p><strong>Turn goals into daily actions: </strong>Winners and losers both set goals, but those who succeed are action-oriented, not outcome-oriented. If you want to supercharge your productivity, you need clearly defined daily actions to check off (<em>pro tip</em>: physically writing them down and checking them off engages the reward tract in the brain, increasing dopamine).</p></li><li><p><strong>Time-blocking:</strong> It&#8217;s not enough to have a to-do list. You need to map daily actions to a specific time of day that you&#8217;ll accomplish them. Make sure you block off enough time for the task and treat that time as sacred. No interruptions or reschedules.</p></li><li><p><strong>Eliminate busy work:</strong> Focus only on what moves the needle, eradicate everything else during your work blocks.</p></li><li><p><strong>Minimize distractions:</strong> Get off your phone, close out unnecessary tabs, turn off non-essential notifications, reduce physical and digital clutter, communicate with your people that you&#8217;re not to be interrupted.</p></li><li><p><strong>Use tools wisely:</strong> AI can speed up learning, synthesizing information, and organizing ideas (use it wisely - don&#8217;t outsource your brain). Pen and paper are useful for focus, retention, and reducing mental load.

ejaculation.</figcaption></figure></div><p><strong>Erectile Dysfunction</strong></p><p>Erection quality relies on proper sexual arousal to trigger penile blood flow. When dopamine becomes depleted in the reward pathway and the prefrontal cortex, arousal is harder to achieve. Alternatively, you can feel aroused but the brain doesn&#8217;t relay the proper downstream signals through the PVN, such as oxytocin and nitric oxide, that trigger erection.</p><p><strong>Premature Ejaculation</strong></p><p>In a low-dopamine state, the brain constantly seeks cheap reward signals, orgasm being one of them. The nucleus accumbens speeds up ejaculation timing, while insufficient D2/D4 (the inhibitory dopamine receptors) and GABA activity can&#8217;t &#8220;put the brakes&#8221; on, lowering sexual stamina.</p><p><a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9312911/">Research</a> shows that restoring dopamine activity by administering D4 receptor agonists, like apomorphine, improves sexual function in rats, highlighting just how central dopamine is to the whole process.</p><p><strong>The Dopamine-Prolactin Axis</strong></p><p>Low dopamine also perpetuates sexual dysfunction via the  <strong>dopamine-prolactin feedback loop</strong>.</p><ul><li><p>Dopamine regulates prolactin in the pituitary.</p></li><li><p>Prolactin literally means &#8220;for lactation.&#8221; Its evolutionary purpose is to suppress sex hormones in favor of lactation. In men, it increases bonding towards mates and children.</p></li><li><p>Prolactin lowers the gonadotropins (LH and FSH) via the hypothalamic-pituitary-gonadal axis. The gonadotropins are what trigger sex hormone production in the reproductive organs.</p></li><li><p>For men, this means <strong>lower testosterone and DHT</strong>, key drivers of sexual function and masculinity.</p></li></ul><p>Evidence supports this connection: men taking 5-alpha reductase inhibitors for hair loss, which lower DHT, reported a <strong><a href="https://pubmed.ncbi.nlm.nih.gov/40971937/">212% increase in sexual dysfunction</a></strong>.</p><p><strong>The Vicious Cycle</strong></p><p>Sexual performance issues can destroy a man&#8217;s confidence. Shame and loneliness can push you to withdraw and seek comfort in more dopamine-depleting habits like porn, social media, or gaming. This only worsens the deficit and further engrains the dysfunction. Overcoming the shame and getting your headspace right are just as important as your physiology when it comes to sexual health.</p><p><strong>The Takeaway</strong></p><p>There&#8217;s no Viagra in nature. If a species&#8217; physiology is so weak that it can&#8217;t reproduce, it goes extinct.</p><p>Sexual performance is a tell-tale sign of dopamine status, but the implications go far beyond that. Building a resilient human race, one that can think freely, live free of medication and centralized control, and act independently starts with healthy dopamine signaling.</p><p>If you&#8217;re dealing with ED or PE, use the <a href="https://www.harrisonbach.com/p/the-dopamine-restoration-protocol">dopamine restoration protocol</a> to get your brain back. Don&#8217;t let shame push you further into loneliness and bad habits.</p><p>I struggled silently for years before getting my physiology back online and mustering the courage to seek relationships. You&#8217;re definitely not alone - men usually just don&#8217;t want to admit it.

In reality, dopamine orchestrates motivation, discipline, learning ability, skill development, movement patterns, and emotional tone. It&#8217;s also a hormonal and metabolic regulator in nearly every system in the body.</p><p>Optimal dopamine makes you feel like a lion. You can focus for long stretches and unplug effortlessly. You&#8217;re healthier, more present, decisive, and can think for yourself.</p><p>But the modern environment destroys dopamine signaling. Constant convenience and stimulation in the form of screens, porn, processed food, social media, recreational drugs &amp; alcohol, and caffeine/nicotine light up the reward system far beyond what the brain was designed to handle.</p><p>On top of that, chronic stress, poor diet, nutrient deficiencies, environmental toxins, non-native EMF, and sleep disruption sabotage the physiology that produces and maintains dopamine in the first place. </p><p><strong>You&#8217;ve probably experienced at least one of the tell-tale signs:</strong></p><ul><li><p>Anxiety, depression, and mood crashes</p></li><li><p>Weak discipline and near-zero motivation</p></li><li><p>Addictive behaviors</p></li><li><p>Sexual dysfunction</p></li><li><p>Brain fog</p></li><li><p>Anhedonia (lack of pleasure)</p></li><li><p>Poor memory and focus</p></li><li><p>Social awkwardness</p></li><li><p>A sense that your brain is constantly sputtering</p></li><li><p>Loss of coordination and balance</p></li></ul><p>The implications go beyond your health. Low dopamine essentially turns you into a consumption machine. You lose your propensity to act especially on hard things, the opposite of &#8220;taking up your cross&#8221; as God instructs. Critical thinking also erodes, you feel less purposeful, and resilience against stress and temptation disappears.</p><p>You can&#8217;t reach your peak without optimal dopamine signaling. Read through the breakdown below and you&#8217;ll understand exactly why, and how you can get it back.</p><p></p><p><em><strong>Dopamine in the Nervous System</strong></em></p><p><em>&#8220;Dopamine participates in almost every centrally controlled event, from motor control to cognition&#8221; (Franco et al. 2021).</em></p><p>In the brain, dopamine is the currency for motivation, movement, learning, and survival. <strong>It&#8217;s meant to reinforce behaviors that help us stay alive and reproduce.</strong> In animal studies, removing dopamine led rats to starve themselves even with abundant food in their environment. That&#8217;s how essential it is for your will to live.</p><p>Dopamine neurons originate from the &#8220;ventral tegmental area&#8221; in the brain and project into several important regions:</p><ul><li><p><strong>Nucleus accumbens</strong><br>Handles reward-seeking behavior. When dopamine signaling is strong you feel motivated and capable of exerting effort towards meaningful goals.</p></li><li><p><strong>Substantia nigra</strong><br>Regulates smooth motor control and habit formation. When dopamine drops here you see slower and uncoordinated movement patterns (low dopamine in this region is the basis for Parkinson&#8217;s disease).</p></li><li><p><strong>Striata</strong><br>Controls decision making, social presence, motor output, habit loops, and reward processing.</p></li><li><p><strong>Amygdala</strong><br>Handles emotional tone and fear regulation. Low dopamine here makes you much less resilient to the point where meaningless stressors trigger anxiety.</p></li><li><p><strong>Hippocampus</strong><br>Essential for memory formation and recall. This is one of the first regions to suffer when dopamine declines.</p></li><li><p><strong>Hypothalamus</strong><br>Controls the autonomic nervous system, temperature, appetite, metabolic rate, and hormonal signaling.</p></li><li><p><strong>Prefrontal cortex</strong><br>Responsible for executive function, focus, discipline, long-term planning, impulse control, and delayed gratification. When dopamine is depleted, the prefrontal cortex loses control and the less evolved limbic system takes over.</p></li></ul><blockquote></blockquote><div class="captioned-image-container"><figure><a class="image-link image2 is-viewable-img" target="_blank" href="https://substackcdn.com/image/fetch/$s_!-ZLn!,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F52a2ba38-a656-4a4e-9b73-2f70badb9be2_650x367.png" data-component-name="Image2ToDOM"><div class="image2-inset"><picture><source type="image/webp" srcset="https://substackcdn.com/image/fetch/$s_!-ZLn!,w_424,c_limit,f_webp,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F52a2ba38-a656-4a4e-9b73-2f70badb9be2_650x367.png 424w, https://substackcdn.com/image/fetch/$s_!-ZLn!,w_848,c_limit,f_webp,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F52a2ba38-a656-4a4e-9b73-2f70badb9be2_650x367.png 848w, https://substackcdn.com/image/fetch/$s_!-ZLn!,w_1272,c_limit,f_webp,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F52a2ba38-a656-4a4e-9b73-2f70badb9be2_650x367.png 1272w, https://substackcdn.com/image/fetch/$s_!-ZLn!,w_1456,c_limit,f_webp,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F52a2ba38-a656-4a4e-9b73-2f70badb9be2_650x367.png 1456w" sizes="100vw"><img src="https://substackcdn.com/image/fetch/$s_!-ZLn!,w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F52a2ba38-a656-4a4e-9b73-2f70badb9be2_650x367.png" width="650" height="367" data-attrs="{&quot;src&quot;:&quot;https://substack-post-media.s3.amazonaws.com/public/images/52a2ba38-a656-4a4e-9b73-2f70badb9be2_650x367.png&quot;,&quot;srcNoWatermark&quot;:null,&quot;fullscreen&quot;:null,&quot;imageSize&quot;:null,&quot;height&quot;:367,&quot;width&quot;:650,&quot;resizeWidth&quot;:null,&quot;bytes&quot;:null,&quot;alt&quot;:&quot;Dopamine and Movement&quot;,&quot;title&quot;:null,&quot;type&quot;:null,&quot;href&quot;:null,&quot;belowTheFold&quot;:true,&quot;topImage&quot;:false,&quot;internalRedirect&quot;:null,&quot;isProcessing&quot;:false,&quot;align&quot;:null,&quot;offset&quot;:false}" class="sizing-normal" alt="Dopamine and Movement" title="Dopamine and Movement" srcset="https://substackcdn.com/image/fetch/$s_!-ZLn!,w_424,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F52a2ba38-a656-4a4e-9b73-2f70badb9be2_650x367.png 424w, https://substackcdn.com/image/fetch/$s_!-ZLn!,w_848,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F52a2ba38-a656-4a4e-9b73-2f70badb9be2_650x367.png 848w, https://substackcdn.com/image/fetch/$s_!-ZLn!,w_1272,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F52a2ba38-a656-4a4e-9b73-2f70badb9be2_650x367.png 1272w, https://substackcdn.com/image/fetch/$s_!-ZLn!,w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F52a2ba38-a656-4a4e-9b73-2f70badb9be2_650x367.png 1456w" sizes="100vw" loading="lazy"></picture><div class="image-link-expand"><div class="pencraft pc-display-flex pc-gap-8 pc-reset"><button tabindex="0" type="button" class="pencraft pc-reset pencraft icon-container restack-image"><svg role="img" width="20" height="20" viewBox="0 0 20 20" fill="none" stroke-width="1.5" stroke="var(--color-fg-primary)" stroke-linecap="round" stroke-linejoin="round" xmlns="http://www.w3.org/2000/svg"><g><title></title><path d="M2.53001 7.81595C3.49179 4.73911 6.43281 2.5 9.91173 2.5C13.1684 2.5 15.9537 4.46214 17.0852 7.23684L17.6179 8.67647M17.6179 8.67647L18.5002 4.26471M17.6179 8.67647L13.6473 6.91176M17.4995 12.1841C16.5378 15.2609 13.5967 17.5 10.1178 17.5C6.86118 17.5 4.07589 15.5379 2.94432 12.7632L2.41165 11.3235M2.41165 11.3235L1.5293 15.7353M2.41165 11.3235L6.38224 13.0882"></path></g></svg></button><button tabindex="0" type="button" class="pencraft pc-reset pencraft icon-container view-image"><svg xmlns="http://www.w3.org/2000/svg" width="20" height="20" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round" class="lucide lucide-maximize2 lucide-maximize-2"><polyline points="15 3 21 3 21 9"></polyline><polyline points="9 21 3 21 3 15"></polyline><line x1="21" x2="14" y1="3" y2="10"></line><line x1="3" x2="10" y1="21" y2="14"></line></svg></button></div></div></div></a></figure></div><p>Dopamine also regulates neurotransmitters, notably the balance between glutamate and GABA. When dopamine is compromised, glutamate drives sympathetic overload as GABA falls. This is the underlying biology of burnout. You feel wired and tired, can&#8217;t focus, can&#8217;t sleep deeply, and anxiety rises. Over time, your movement quality and sexual function break down.</p><p></p><p><em><strong>Dopamine in the Body</strong></em></p><p>Most people don&#8217;t realize over 99% of dopamine exists outside the brain. Dopamine receptors cover the gut lining, liver, kidneys, pancreas, immune system, thyroid, adrenal glands, gonads, and heart.

heat production), insulin and leptin sensitivity, glucose and fat metabolism, thyroid hormone, and energy expenditure.</p></li><li><p><strong>Gut health</strong></p><p>Dopamine influences gut motility, microbiome behavior, gut lining repair, and GLP-1 production.</p></li><li><p><strong>Daytime alertness &amp; sleep quality</strong></p><p>Dopamine follows a diurnal rhythm. High baseline levels during the day influence alertness and drive while low nighttime levels are required for melatonin release. Phasic bursts throughout the night are also required for REM sleep architecture.</p></li><li><p><strong>Sex hormone production</strong></p><p>Low dopamine levels increase prolactin in the hypothalamus, which suppresses the gonadotropins (LH &amp; FSH). This results in low testosterone/DHT for men and suboptimal estrogen/progesterone for women.</p></li><li><p><strong>Chronic stress</strong></p><p>Regulation of the vagus nerve and HPA axis relies on optimal dopamine signaling.</p></li><li><p><strong>Sexual function</strong></p><p>Sex is the most dopaminergic stimulus we were meant to experience. Dopamine sits at the center of libido, erection quality, timing of ejaculation, and orgasm.</p></li><li><p><strong>Athletic performance &amp; recovery</strong></p><p>Dopamine firing influences muscle contractions, force output, motor learning, and muscle protein synthesis. It also reduces injury through movement quality and enhances immune function and bone turnover.</p></li><li><p><strong>Hydration</strong></p><p>Dopamine&#8217;s effects on vasopressin, aldosterone, and prolactin alter water and electrolyte gradients.</p></li><li><p><strong>Reaction time</strong></p><p>Quick discernment and decision making relies on rapid firing of dopamine neurons.</p></li></ul><p>Dopamine depletion clearly isn&#8217;t just a mood or motivation issue. It creates a whole-body performance collapse.</p><p></p><p><em><strong>How Modern Life Hijacks Your Dopamine System</strong></em></p><p>Dopamine was originally designed to respond to meaningful stimuli that required effort and benefitted our survival. Sex, sunlight, real food, connection, and innovation were the biggest dopamine triggers and they were relatively rare. The pain-pleasure balance favored pain, which kept dopamine peaks moderate and sustainable.</p><blockquote></blockquote><div class="captioned-image-container"><figure><a class="image-link image2

Not just drug addiction - I&#8217;m convinced the vast majority of us have underlying addiction to technology and recreational stimulants like caffeine (which is essentially a legalized drug). Eventually, long-term dopamine breakdown forms the basis of dementia, impotence, and other chronic health issues.</p><p>On the other side of the coin is the breakdown of dopamine biochemistry. Even if you removed all dopaminergic stimulation, you still need the raw materials and physiology to synthesize dopamine in the first place. Chronic stress, nutrient deficiencies, blue light &amp; nnEMF exposure, disrupted circadian cues, and environmental toxins reduce mitochondrial function and block the enzymes involved in dopamine production and turnover. </p><p>Hopefully, you&#8217;re starting to grasp the far-reaching implications of low dopamine, whether you&#8217;re an average joe or an elite performer. Rebuilding it takes awareness, time, and effort.</p><p></p><p><em><strong>How to Restore Dopamine: The Science and Protocol</strong></em></p>
