Calling sunscreen anti aging is a joke You’re blocking the very UV and infrared light your skin uses to build collagen, make Vitamin D3, generate nitric oxide, and stimulate melanin based photo-protection All sunscreens (both chemical and mineral based) disable natural photoadaptation and mitochondrial signaling, processes that actually preserve skin structure and youth “When it’s black, it don’t crack” is a cultural truth pointing in the direction of eumelanin, but also melanin at large Nature already equipped melanin rich skin with a full spectrum sunscreen and anti aging mechanism And guess what All skin types have melanin, you just have to maximize its longevity and function through a circadian aligned lifestyle and sunbathing framework

Circadian eyesight regeneration isn’t some fringe idea, it was the norm for our ancestors Long before screens, sunglasses, and artificial light, human vision was constantly bathed in the sun’s full spectrum from sunrise to sunset The daily dance between light during the day and darkness at night trained, nourished, and regenerated the visual system Our eyes evolved in lockstep with the sun, not under fluorescents or LEDs Mitochondria are circadian controlled organelles. Opsins are circadian controlled light sensing proteins. Melanin is a circadian and electromagnetic biological polymer These are all light sensing mechanisms central to eye function and longevity What we call “decline” today was once prevented naturally, and often reversed, through nothing more than consistent circadian alignment Your ancestors didn’t need eye exercises or blue light blocking lenses to preserve their vision, their entire lifestyle was an ocular regeneration protocol because nature built it in as a feature Every phase of daytime light carries specific frequencies that tunes and maintains the melanin, photoreceptors, retinal pigment epithelium, mitochondria, and even ocular blood flow Contrast that with today People spend 90%+ of their time indoors on average, staring at backlit screens under static artificial light The retina is starved of the spectral diversity and rhythms it evolved to depend on It’s no surprise that myopia, dry eye, and degenerative eye diseases are skyrocketing The problem isn’t genetic, it’s epigenetic based on chronic circadian disruption because the environment has changed drastically This isn’t pseudoscience, your own beloved mainstream research confirms the power of light for vision Longer wavelengths like red improve color contrast vision with a single three minute exposure, with it lasting for up to one week Violet light stops myopia through the activation of the EGR1 gene in human beings Red and infrared regenerates opsins, while retinal dopamine made by bright light from the sun improves photoadaptation Blue light activates melanopsin within intrinsically photosensitive retinal ganglion cells, creating systemic circadian alignment Green light for the improvement of headaches/migraines as shown through the work of Dr. Tom Seager, with that light into the eyes peripherally being a key component of the process UV-A stimulates the release of nitric oxide and activates the pituitary-retinal axis, affecting dopamine and other neurotransmitters crucial for eye growth and focus regulation UV-B influences ocular immune regulation and indirectly supports tear film and corneal health through systemic pathways This is some of the most well grounded science available to human beings, but your optometrist and ophthalmologist don’t know that

Modern medicine is broken You can preach about how great it is for acute care, and I’ll agree, but that’s a distraction from the real issue People like me who’ve experienced iatrogenic harm don’t care about excuses. We’ve been burned, directly or indirectly, by the very system meant to heal As an example, the system itself, a medical bureaucracy, inflicted harm by penalizing my midwife who acted in my family’s best interest during an emergency. That’s institutional iatrogenesis Heavy is the head that wears the crown, so take it on the chin, not up the ass Knowing what iatrogenesis means ≠ reflecting on your role in perpetuating it. Every pilot understands gravity, that doesn’t mean crashes aren’t caused by bad training or broken systems Complexity doesn’t excuse negligence or misaligned incentives. It’s one thing to accept risk, while it’s another to normalize harm as inevitable Patient “self-harm” is often secondary to a system that fails to educate, empower, or create health literate citizens. The culture conditions dependency, then blames the dependent. Sounds like an abusive and alcoholic parent “Don’t confuse your Google search with my medical degree” is the type of arrogance I’m talking about When the entire model rewards treatment over prevention, blaming the patient for acting “autogenically” is hypocrisy Yes, doctors may be more ethical than pharma execs or insurers, but that’s like saying the captain’s the most sober man on a sinking ship Ethics are relative within the system, and that doesn’t absolve the profession’s complicity in the machine I’ve seen more people heal from sunrise, movement, and truth than from any prescription written under fluorescent lights Modern medicine doesn’t own health, but people are waking up, literally and figuratively If I break my leg, I’m obviously going to the hospital. If I have an acute situation that requires a hospital visit, I’ll have no problem going That’s what modern medicine should be for. Acute trauma, emergencies, saving lives when seconds matter But don’t treat me like a fucking idiot who’s incapable of learning, thinking, or discerning truth for myself Because where I’ll actually find health, where I’ll reverse disease, restore energy, and build resilience will never be inside those walls lit by toxic lighting It’ll be outside In the sun, in the cold, in the rhythms of nature that trained my biology long before medicine tried to manage it

There are many Vitamin D metabolites that differ in water solubility, how long they last, and their ability to be reactivated in tissues when needed This means your body can store Vitamin D in different forms, keep it circulating longer, and reactivate it on demand, hence Vitamin D status isn’t just about new production, but also how well your system manages and taps into these reserves Because of this, someone with strong metabolic and circadian rhythms can stay Vitamin D sufficient longer, even with little sun, by cycling and reusing stored forms efficiently On the flip side, if those pathways are disrupted, your body will likely struggle to access or convert those stored metabolites, leading to deficiency even if you technically have plenty in the bank Skin type absolutely matters, but mainly upstream, at the level of how much Vitamin D you can make and store in the first place, not so much in the downstream recycling Darker skin makes Vitamin D more slowly because higher eumelanin blocks UV-B more effectively, but once D3 is produced and metabolized, the sulfation, storage, and recycling pathways work similarly Lighter skin can build up stores faster with less UV-B exposure, but if circadian rhythms or metabolic health are poor, they can burn through or fail to mobilize those stores just as easily This is such a game changing and refreshing narrative involving Vitamin D3 acquisition and storage

For many, this is true

Most melanomas occur on body parts that rarely see the sun This alone should make you pause. If full spectrum sunlight were the primary culprit, you’d expect the highest melanoma rates on chronically sun exposed areas like the face, neck, and forearms Instead, melanomas overwhelmingly appear on the trunk, thighs, and other typically covered areas That pattern doesn’t scream UV causation, it points to something deeper, like systemic chronic circadian and metabolic dysfunction

Here’s where mechanisms meet the real world results, and I love to see it because my most recent Substack article explains much of the why behind this Most think it’s impossible for Vitamin D levels to rise through a cold, “sun and UV poor” Canadian winter despite no supplementation 1. Mobilization of fat stores during cold exposure. 25(OH)D is fat-soluble and stored in body fat. Frequent cold exposure increases sympathetic tone, brown adipose tissue activation, and lipolysis, which mobilizes stored lipophilic compounds, including Vitamin D metabolites, into circulation In winter, you’re not necessarily producing new Vitamin D through skin UV-B exposure, but your body is liberating what you stored during summer, raising serum levels 2. Enhanced sulfation and circulation dynamics in cold Cold exposure upregulates hepatic sulfotransferase activity and improves peripheral circulation Sulfated Vitamin D metabolites like 25(OH)D₃-3-sulfate) are more water-dispersible and can act as a circulating reserve pool, re-entering active circulation when lipolysis and transport proteins shift Likely making more Vitamin D bioavailable or detectable in standard blood tests depending on the assay 3. Seasonal hormonal and binding protein fluctuations Vitamin D–binding protein and albumin levels are not static, they fluctuate seasonally and under stress. Cold exposure, changes in liver metabolism, and altered circadian photoperiods can shift DBP levels. A lower DBP concentration can increase the proportion of free and bioavailable 25(OH)D, which can raise measured total levels depending on the test 4. Reduced conversion to active metabolites In colder months, metabolic rates and sun exposure patterns shift. If less 25(OH)D is being converted to 1,25(OH)₂D (the active form), the circulating pool of 25(OH)D might actually RISE because less is being drawn downstream Think of it like reduced spending during hibernation, the checking account balance creeps up because withdrawals slow down 5. Circadian and photoperiod adaptations Even without external UV-B, proper light entrainment through getting AM light daily keeps the hepatic-renal axis and hormonal cascades in sync, further supporting efficient recycling and conservation of Vitamin D metabolites Circadian alignment creates more efficient Vitamin D homeostasis ••• All this points to some fascinating overlap that most people do not consider A winter rise in Vitamin D likely reflects a synergy of three processes: 1. Mobilization of stored lipophilic D metabolites through cold-induced lipolysis 2. Enzymatic reconversion of conjugated metabolites into measurable 25(OH)D 3. Endogenous biophoton UV-B photochemistry acting on cholesterol/sulfated precursors, sustaining low level Vitamin D production even in the absence of external UV-B This is why I advocate for sunbathing when the time is right, so you can build that reserve of Vitamin D metabolites In winter, especially with cold exposure and good circadian hygiene, your body liberates and conserves those stores more efficiently, oftentimes enough to increase serum Vitamin D, even without new synthesis The human animal is built for this

Maybe your Vitamin D3 levels aren’t meant to stay sky high all year Maybe, just maybe, life is built on seasonal duality, not perpetual summer Even at the equator, there’s no such thing as true perpetual summer, it’s just a different kind of rhythm. The sun might rise and set at nearly the same time year-round, but rainfall patterns, food availability, humidity, and cloud cover create their own seasonal cues that living systems have adapted to Equatorial populations still experience cycles, they’re just less about temperature and more about rain, light diffusion, and ecological shifts. The body still syncs to these environmental rhythms So the idea of keeping D3 status or any biological marker “locked in” year-round is ahistorical and biologically tone deaf Even nature’s most stable environments pulse Modern thinking treats health like a thermostat. Pick an “optimal” number and lock it in What they fail to understand is that biology is rhythmic. Vitamin D3 levels naturally rise with abundant UV-B in summer and decline through winter, mirroring changes in light, temperature, food availability, and circadian gene expression, so forth Forcing levels to remain elevated year-round through supplements or artificial UV ignores this deeper rhythm and turns you into a neurotic pain in the ass Winter is a different operating mode Just like trees shed their leaves, your physiology shifts gears.. altering hormone cascades, immune tone, and metabolic priorities. Flattening these seasonal waves may feel optimized on paper, but it often clashes with how humans actually evolved to function The point? Health isn’t about constant abundance, it’s about respecting the ebb and flow
