Wearing glasses blocks harmful UV light, which we avoid indoors and in cars. UV light from the sun activates vitamin D, lowers blood pressure, benefits the heart, arteries, and cholesterol, aids in weight loss, helps with skin conditions and diseases, and boosts melatonin for better sleep. The sun is demonized to support industries selling supplements and other products.

Speaker 0 asks: Should we stop wearing sunglasses? Speaker 1 responds: Yes. Except we should be wearing them indoors and at night, not outdoors during the day. When you wear sunglasses outdoors, they block the UV, and that's kind of what most people wear them for. Things are bright. Well, reason things are too bright for most people is because they don't get out at dawn to see the sunrise. And if they did, their eyes would adjust to the sun and they wouldn't need sunglasses. We've been told forever from optometrists and doctors that UV is bad for the eyes. And in fact, our eyes have receptors to read the ultraviolet light. And when we cover them with sunglasses, we cannot read how much UV is in the sun, and so we get sunburned. Speaker 0 asks: So you are an expert in all things circadian rhythm and light diet. So what time are you waking up, and what time are you going to bed? Speaker 1 answers: So this eight hours of sleep a night, I think is bull. I wake up with the sun. I actually need to sleep less in the summer and more in the winter, and that's how we're biologically designed. We are a light poisoned population. The light that we're exposed to is highly intense in the blue color of light. There's no infrared, almost zero red light, very little yellow, and a ton of blue light. Blue light in itself is not bad, but blue light becomes toxic when we're exposed to too much of it. It messes with our circadian rhythm. It is actually associated with cancer, heart disease, diabetes, and obesity if we see it after sunset, and macular degeneration during the day because we have so much of it hitting our eyes causing free radicals.

Skin cancers are the most commonly diagnosed cancer in the US, and the public is constantly told to avoid the sun to prevent them. However, while relatively benign skin cancers are caused by sun exposure, the ones responsible for most skin cancer deaths are due to a lack of sunlight. Sunlight is arguably the most important nutrient for the human body, as avoiding it doubles one's rate of dying and significantly increases their risk of cancer. A strong case can be made that the dermatology profession rebranded themselves to skin cancer fighters, allowing them to become one of the highest paying medical specialties. Despite billions spent each year, there has been no substantial change in skin cancer deaths. Sunlight is critical for mental health, and women with higher solar UVB exposure had half the incidence of breast cancer. Men with higher residential solar exposure had half the incidence of fatal prostate cancer. A study found sun avoidant women were 60% more likely to die. Nonsmokers who avoided the sun had the same risk of dying as smokers who got sunlight.

Dermatology's war against the sun may be disastrous, as benign skin cancers are caused by sun exposure, while the deadliest skin cancers are linked to lack of sunlight. Sunlight is arguably the most important nutrient, and avoiding it doubles one's rate of dying and increases cancer risk. The dermatology profession rebranded itself as skin cancer fighters, becoming a high-paying specialty, yet skin cancer deaths haven't substantially changed. Sunlight is critical for mental health; nurses lacking sun exposure had worse mental health. Higher solar UVB exposure was linked to half the incidence of breast cancer in women and fatal prostate cancer in men. A study found sun avoidant women were 60% more likely to die. The largest benefit of sun exposure was seen in smokers. The American Academy of Dermatology says skin cancer is the most common cancer in the US, but most diagnosed skin cancers are benign. They encourage staying out of tanning beds and using sunscreen. Basal cell carcinoma, linked to sun exposure, rarely metastasizes and has a near-zero fatality rate.

The sun does not cause cancer; cancer is a metabolic disease. Estrogen doesn't cause cancer either. Cellular stress and oxidative stress from seed oils, sugar, and alcohol can contribute to cancer. People who "bake" in the sun often use sunscreens with carcinogens and consume unhealthy foods and drinks like beer, chips, and salsa, which contain rancid seed oils. These factors, combined with sun exposure, can cause cancer.

Dr. Alexis Cohen (Jasmine Cohen) and the host discuss a wide-ranging view of health, science, and society, centered on mitochondria, light biology, and decentralized approaches to knowledge and healing. - On science, health, and authority: - Cohen argues that “we really haven’t been doing science for about seventy years now” and that modern science has become scientism, with people looking to scientists and doctors as authority figures over personal health, even though no one can fully know another’s lived body experience. - She emphasizes that aging is a reflection of mitochondrial heteroplasmy and that there are ways to slow or speed that burden, but contemporary living habits harm mitochondrial health. She asserts there are incentives to promote lifestyle advice that is not monetizable (outdoor activity, barefoot grounding, seasonal eating, movement), which she says slows research and access to information. - The conversation asserts a need to reclaim personal authority over health and to recognize life as magical and miraculous. - Personal entry into Bitcoin and crypto curiosity: - Cohen notes she and her partner became interested in Bitcoin in 2018, with a continued engagement including taking a cryptography course to understand the underlying proofs rather than accepting information at face value. - Background and work: - The host introduces Cohen as a Princeton-trained molecular biologist, a PhD focusing on metabolism, gut health, and circadian biology, who shifted from academic research to helping people rebuild health through nutrition, movement, mitochondrial function, and light exposure. Cohen shares that her own childhood illnesses, weight issues, and colitis prompted a pivot from academia to health coaching, emphasizing ownership of wellbeing through science and practical lifestyle strategies. - Cohen highlights that she values rigorous science but seeks practical lifestyle strategies to empower clients to understand their biology and take ownership of their health. - Dance, embodiment, and biology: - Cohen describes taking up social dancing (salsa, bachata, merengue, fox trot, hustle) and training intensely. She explains dancing challenges the brain in novel ways, requires being guided by a partner, and expands neural connections. - The host shares similar experiences with dance, noting body memory across decades and the importance of movement, rhythm, and social connection for health. - Mitochondria, heteroplasmy, and light: - Cohen explains mitochondria as the battery of the cell, with their own circular DNA and multiple roles in ATP production, biosynthesis, and epigenetic regulation. Heteroplasmy, the mutation burden in mitochondrial DNA, reflects dysfunction that can lead to energy production deficits across tissues. - She notes three key mitochondrial outputs: - ATP production powers cellular processes and metabolism. - Metabolic water production (including deuterium-depleted metabolic water). - Biophotons, photons largely in the UV range, emitted by mitochondria and nucleus during electron transport; older, sicker individuals emit more light due to increased permeability of the system. - Cohen argues aging mirrors mitochondrial heteroplasmy and mutation accumulation, with higher mutation burdens in tissues like immune cells, gut, liver, and brain associated with disease. She also discusses that mitochondria contribute to energy, water, and biophotons, and that modern life elevates heteroplasmy by lifestyle choices. - She argues heteroplasmy can be slowed or sped, and that there are actionable interventions—though the exact list is not exhaustively enumerated in this segment. - Why mitochondrial health isn’t the central target: - Cohen says mitochondrial health research is less profitable because it emphasizes lifestyle and environmental changes rather than drugs, which affects funding and research direction. She describes a system where focusing on broad environmental and lifestyle changes could be financially less lucrative than drug-centered approaches. - She expands on historical dynamics in science, including siloing of scientists and the development of a paywalled academic publishing model, suggesting that the system discourages holistic, integrative approaches that would unify mitochondrial biology with systems biology. - Light, circadian biology, and UVA/UVB: - The discussion shifts to light as a regulator of mitochondria. Cohen divides the sun’s spectrum into ultraviolet (UVB and UVA), visible light, blue light, and near infrared (NIR). She emphasizes that near-infrared light penetrates deeply and stimulates mitochondria, while UVB promotes melanin production via POMC and MSH peptides, affecting energy balance, mood, and metabolism. - UVB light triggers alpha-MSH and beta-endorphin production, the latter contributing to mood and dopamine support, and helps regulate energy expenditure and appetite via POMC-derived pathways; UVB exposure supports melanin synthesis, redox balance, and photoreception across tissues. - UVA light activates Neuropsin receptors on eyes and skin, aiding circadian entrainment and nitric oxide production, which improves vasodilation and nutrient delivery. Neuropsin is present in skin and testes; its stimulation is linked to testosterone and fertility enhancements. UVA also helps anchor local circadian rhythms in tissues. - Cohen discusses the misperception that UV light is universally harmful and argues that melanin is not only protective but can facilitate energy capture from high-energy photons to support energy metabolism in humans. Melanin’s roles extend beyond protection to potential energy transduction, with POMC, MSH, and alpha-MSH linking light exposure to metabolic regulation. - The My Circadian app is recommended as a tool to track sunrise, UVA/UVB rise, and lux (brightness) to optimize exposure. Cohen notes indoor environments rarely exceed 1000 lux, while outdoor brightness can reach 60,000–60,200 lux, significantly impacting serotonin production, mood, and cognition. She emphasizes the importance of bright daytime light for circadian alignment and melatonin suppression at night. - Infrared, LEDs, and indoor lighting: - The conversation covers lighting technologies, noting fluorescent tubes and LEDs minimize near-infrared and maximize blue light, which disrupts circadian rhythms and flicker, stressing the eyes and sympathetic nervous system. Cohen argues that modern lighting deprives people of infrared and UV radiation, both critical for mitochondrial function and circadian health. - She criticizes the push for energy efficiency that reduces thermal and infrared energy, arguing it contributes to systemic health issues. She emphasizes the importance of incandescent and near-infrared-rich lighting for indoor environments and sun exposure to sustain metabolic health. - Grounding, EMF, and environmental exposure: - Grounding (direct contact with the earth) is presented as a way to discharge excess positive charge in tissues, reducing inflammatory burden and supporting mitochondrial function. Cohen shares practical grounding instructions—grounding directly to the earth when possible, wearing natural fibers, and using grounding footwear. - Non-native electromagnetic fields (EMFs) from Wi-Fi, Bluetooth, 5G, and other sources are discussed as contributors to mitochondrial dysfunction and inflammation. Cohen cites Robert Becker’s historical work on non-thermal EMF effects and Havana syndrome as context for potential biological risks. She suggests practical mitigation, including reducing EMF exposure, using Ethernet where possible, and using tinfoil to shield exposure in certain situations. Plant life can absorb EMF, and grounding, sunlight, and strategic use of red and infrared light are recommended to compensate where exposure is high. - The discussion includes practical home strategies, EMF-blocking window panels, EMF-blocking paint, and even temporary shielding (e.g., tinfoil) as a do-it-yourself mitigation approach. - Travel, circadian disruption, and protocols: - Cohen outlines travel challenges: high altitude cosmic radiation exposure (non-AVMF exposure), cabin EMFs, circadian misalignment, and sedentary behavior. She suggests pre- and post-travel strategies such as grounding, sun exposure, hydration, lymphatic support, and blue-light management to ease time-zone transitions. - She promotes an ebook protocol focused on lymphatic support and circadian realignment, available for purchase, with a holiday discount code holydays. Blue-light blocking strategies and red-light strategies are included to facilitate adaptation to new time zones. - Health, mental health, and pediatric considerations: - The hosts discuss mental health concerns, including PTSD, anxiety, and depression, emphasizing circadian regulation, light exposure, sleep hygiene, and reducing screen exposure. Cohen notes the importance of bright daytime light and a dark, cool sleeping environment for sleep quality and mood. She mentions a study showing even small nighttime light exposure can influence daytime metabolic markers, emphasizing the importance of darkness at night. - Birth, medications, and vaccines: - They touch on birth experiences, epidurals, and how early life interventions can influence long-term health and microbiome development. Cohen discusses pain as a portal to healing and critiques reliance on certain pharmaceutical approaches. - On vaccines, Cohen describes observed adverse effects post COVID-19 vaccination, including histamine issues, barrier permeability, and rapid cancer reports linked to vaccine exposure, while underscoring the lack of widespread funding to investigate these relationships. She mentions turbo cancers and batch variation as topics already discussed by researchers like Kevin McKernan and a need for independent inquiry. - Decentralization, science, and Bitcoin again: - Cohen envisions a decentralized health system in which multiple modalities (acupuncture, Chinese medicine, Ayurveda, allopathic medicine) can be tested for proof of work, with outcomes guiding what works best for individuals. She believes decentralization is necessary for genuine innovation, with a future vision of a decentralized, funded light research lab and a retreat model to study circadian biology, mitochondrial function, and nature-based health in diverse environments (North America and equatorial regions). - She sees Bitcoin as a tool that enables financial sovereignty and autonomy, providing an opportunity to fund decentralized science and publish findings on blockchain to protect against censorship. She highlights the potential for Bitcoin to support a lab through deflationary funding and to empower researchers and patients alike. - Closing: - The conversation closes with practical resources: Thinkific-hosted classes, an online book club, and a QuantumU course that reframes science education around decentralized, nature-based principles. Cohen emphasizes accessible contact options (Instagram and email) and a holiday discount for courses and ebooks. The participants express enthusiasm for ongoing collaboration, travel and events, and continued education in Bitcoin, science, and holistic health. Overall, the episode centers on mitochondria as a foundational health driver, the essential role of light and circadian biology in energy, mood, metabolism, and aging, and a call for decentralized, nature-aligned science, with Bitcoin framed as a funding and governance tool to empower individuals and researchers to pursue health innovation beyond centralized institutions.

Exposing yourself to sunlight can naturally heal your body, but many people are unaware of this phenomenon. Unfortunately, we have become afraid of the sun due to the introduction of sunglasses, which have been linked to an increase in cancer cases. Sunglasses filter out certain rays of the sun that are essential for our bodies. The pineal gland, which receives sunlight, needs the full spectrum of light to function properly. Our lens breaks down white light into seven colors, which are encoded with chemicals in the pineal gland and then distributed to different parts of the body for basic metabolic processes.

Here are five reasons to get sunlight for your health. First, UVB rays absorbed by the skin produce vitamin D, which is vital for many bodily processes. Second, light absorbed, especially by the eyes, increases serotonin production, improving mood. Third, sunlight, particularly in the early morning, affects the circadian rhythm, improving sleep. Fourth, sunlight improves immune function, specifically T-cell function, and vitamin D production also modulates immune activity. Fifth, UVA rays absorbed by the skin release nitric oxide, a vasodilator, which expands blood vessels and lowers blood pressure.

Getting sunlight in your eyes first thing in the morning is vital to mental and physical health. It is perhaps the most important thing to promote metabolic well-being, hormone system functioning, and positive mental health. The protocol is to get outdoors, ideally without sunglasses if safe, even with cloud cover. More light information comes through cloud cover than from a bright indoor bulb, making getting outdoors absolutely key.

Humans ask how long they can be in the sun because they've been brainwashed to fear it, unlike animals. The sun provides UVB, which has two main functions: manufacturing vitamin D, only one of thousands of photoproducts, and triggering warning signs when it's time to get out of the sun. The feeling of warmth indicates it's time for shade. Sunscreen prevents UVB from doing its job, causing people to stay in the sun too long and be exposed to damaging parts of the solar spectrum. Listening to your skin and avoiding sunscreen allows nature to guide sun exposure.

UV light lowers blood pressure. UV light increases the efficiency of the heart. UV light improves EKG. UV light balances cholesterol. UV light assists in weight loss. UV light is a treatment for skin conditions. UV light is also an effective treatment for many disorders. Going back to light therapy of 1933 in Germany where they used to heal people with light, then you go UV light increases the level of hormones. People suffering from low testosterone or altered estrogen sitting in the sun. Then we go UV light activates important skin skin hormones such as vitamin d, natural sources. Now why do they tell people to stay out of the sun? Because all these industries exist to keep making money on the people. And if you tell people that UV is toxic and you better stay out of that sun, well, then these industries continue to keep just going about. And that's what we see because these industries have been going on for a long time. Hundred about a hundred years of being told lies. And all we're doing, debunking it one step at a time.

Sunglasses may trigger a massive increase in cancer because they filter out rays of the sun that are supposed to enter the body. The pineal gland requires the entire spectrum of light for basic metabolic processes, including UV light. UV light allows the production of a hormone in the brain responsible for melanin production, which protects the skin. Without this hormone, skin becomes susceptible to sunlight. Wearing sunglasses makes the body think it's dark, preventing the production of this protective hormone. Light is essential for cell communication, growth, and reproduction, which is necessary for the constant regeneration of the body.

Some believe that sunlight can cause skin cancer, but there is no proof to support this claim. In fact, lack of sunshine can actually lead to skin cancer. A recent study found that it is not UVB rays from the sun that cause cancer, but rather UVA rays. Many sunscreens only block UVB rays, which can prevent sunburn but still allow UVA penetration. Sunscreens that block both UVA and UVB rays may seem safer, but they can lead to vitamin D deficiency, which increases the risk of cancer. It is important to avoid sunburn, but gradually increasing sun exposure can help develop a natural protection called tanning. Interestingly, countries with high UV radiation have lower rates of skin cancer compared to countries with less sun exposure. Sunscreens can also be harmful as they contain carcinogenic chemicals that can be absorbed into the bloodstream and potentially lead to liver damage and skin cancer. Additionally, washing off sunscreen with soap can remove any vitamin D that may have been produced on the skin. It is advised to avoid using soap immediately after sun exposure to allow the absorption of vitamin D.

Most skin cancers are caused by wearing sunglasses. People in London and Prague wear sunglasses even when there's no sun, which proves marketing is legalized lying. Women shouldn't use makeup with sunblock. Sunburn isn't as bad as dermatologists claim; it means you're not building a good solar callus. Trees don't wear clothes or sunscreen. Humans are the only animals that believe blocking the sun is smart. You should never block the sun. The key protection is upregulating melanin production in your skin and eyes. To do this, stop wearing sunglasses.

Most sunscreens block UVB rays, which prevents burning, but this doesn't mean UVA rays are blocked. UVA rays penetrate deeply, causing DNA damage, inflammation, and potentially cancer. Sunscreens with UVB-blocking chemicals create a false sense of security, leading to increased sun exposure and UVA penetration. To protect yourself, use broad spectrum sunscreens.

Speaker 0 argues that our ancestors did not spend all day inside looking at a cell phone; our eyes were designed to interact with the sun’s light. The speaker claims that in 1980 the introduction of “sunphobia” with sunscreen and sunglasses, which look cool but block light, marked a shift, and that regular exposure to natural sunlight is therapeutic for the eyes. They state that UV light and infrared into the eye are beneficial, with infrared being healing and helping to build up melatonin in the eyes, which is described as one of the most powerful antioxidants in cells. The speaker asserts that the sun phobia is a huge mistake and that UV radiation to the eyes is not nearly a problem when protected. They recommend getting more light into work or study spaces and eating foods high in lutein and zeaxanthin, two carotenoids found in egg yolks, to support eye health.

One recommendation is to get more sunlight for sulfate production, despite concerns about skin cancer from sun exposure. Mineral-based sunscreen is not recommended due to toxic aluminum content. The rise in melanoma rates may be linked to sunscreen use and glyphosate exposure, which disrupts melanin production. Building a gradual tan in spring is suggested as a natural protection against sun damage, eliminating the need for sunscreen.

Sunlight has benefits, including reducing the size of internal cancer tumors. While there are warnings about sun exposure causing cancer, a study at Baylor University revealed interesting results. Two groups of animals were fed different diets: one a standard American diet, and the other a highly nutritious diet. When exposed to ultraviolet rays, 25% of the animals on the standard diet developed skin cancer, while none on the nutritious diet did. This suggests that diet plays a significant role in cancer risk. Skin cancer is a relatively recent issue, emerging over the last 60 years, whereas our ancestors, who lived and worked outdoors, did not experience it at the same rates.

Sunglasses are necessary in environments with intense light reflection, but generally, they are a bad idea. The eye has mitochondria that function best with red light from sunlight and nonvisual photoreceptors that detect UVA light. Wearing sunglasses all the time blocks the biological signal for the body to produce melanin, which is a natural protection against the sun. This can lead to more severe burns and increase the risk of melanoma and other negative consequences.

Sunlight is our greatest form of natural energy, and we are like walking solar panels. Covering up our skin is like putting tarps over solar panels on our roofs, preventing us from absorbing energy. Taking oral Vitamin D supplements reduces the body's ability to produce it naturally, down-regulating hormonal production. Doctors often recommend taking Vitamin D without testing blood levels, prescribing arbitrary amounts like 5,000 or 10,000 IU daily for years. This can lead to the body's inability to raise levels or produce Vitamin D from the sun because the normal systems have been down-regulated. Introducing something into the system always has consequences.

Ultraviolet light is portrayed as dangerous and something to avoid at all costs. People live and work in environments blocking UV light through glasses, contacts, sunglasses, cars, offices, and artificial lighting. When exposed to the sun, sunscreen is applied, further blocking UV light. However, UV light activates vitamin D, negating the need for synthetic supplements. UV light also helps lower blood pressure and benefits the heart, arteries, and cholesterol. Additional benefits include assisting in weight loss, helping with skin conditions and other diseases, and boosting melatonin levels for better sleep. The claim is that an industry has been created to promote sun avoidance to benefit other industries.

Vitamin D is described as a "God-given miracle" essential to our natural design. While dermatologists often warn against sun exposure due to skin cancer risks, the speaker claims that more people die from lack of sun exposure and related cancers. The speaker asserts that adequate vitamin D levels can reduce all cancers by 50%. While supplements can raise vitamin D levels, the ideal method is sun exposure with minimal clothing, allowing the body to convert a cholesterol precursor into vitamin D. This process affects 10% of our genomics, optimizing our genes. UVA radiation is identified as the more dangerous type, while UVB radiation enables vitamin D production. Sunscreens filter UVB, hindering vitamin D synthesis, while allowing UVA to pass through, potentially increasing skin cancer risk. Studies allegedly show that sunscreen use increases the risk of skin cancer.

Eighty-five percent of the world's population is clinically deficient in vitamin D3, a nutrient humans make from sunlight and cholesterol. Vitamin D3, or cholecalciferol, is arguably the most important nutrient in the human body. People have been taught to fear the sun, but most are not getting enough. The rise in skin cancer incidence is superimposable with the use of sunscreen. Since 2018, multiple brands of sunscreen have been pulled from the market for directly causing skin cancer.

Wearing glasses blocks harmful UV light, but UV light has benefits like activating vitamin D, lowering blood pressure, improving heart health, aiding weight loss, treating skin conditions, boosting melatonin for better sleep. Avoiding the sun supports industries selling supplements, skincare, and more.
