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.

The speaker explains that you can reset your sleep pattern in just two days by controlling your circadian rhythm with light. The key factor in sleep quality is the circadian rhythm, and light is the best controller of that clock. The recommended practice is thirty minutes of natural daylight exposure first thing in the morning. This exposure should be through unfiltered daylight (not through filtered windows or sunglasses) and is best done outside. Do not look directly at the sun; the morning light needs to hit your eyes indirectly for twenty to thirty minutes. When this light reaches the cells at the back of the eyes, it signals the brain that it is daytime, triggering a wake-up response with a surge of cortisol and insulin, and you’re off and running. About fourteen to sixteen hours later, the body naturally releases melatonin, the sleep hormone. Without adequate morning light, the brain doesn’t receive the signal, and the sleep cycle can drift, leading to difficulty falling asleep on time or waking up groggy. The guidance also suggests getting a small amount of evening light as dusk approaches, which helps reinforce the sense that the day is ending. For practical implementation, tomorrow you should step outside for a stroll or simply sit near a clear window and sip your coffee, with no gadgets, no supplements, and no cost involved. This routine aligns with what humanity has done since the dawn of time to sleep deeper, longer, and better. Additionally, if you wear a smartwatch or activity tracker that monitors sleep, you may see positive changes as you manage light. The speaker emphasizes that using and managing light is very good for hormones and is one of the most critical parts of sleep hygiene.

Number one, early morning sunlight contains a very specific wavelength that stimulates a specific area in your brain that basically reboots your circadian rhythm and resets your day night cycle. Number two, morning sunlight stimulates cortisol release and it stimulates it at the right time. Cortisol is the wake up hormone. Number three, when you get low angle sunlight into your eyes, the retina stimulates your brain to release serotonin and dopamine, which are the feel good neurotransmitters. This improves your overall mood, your level of alertness, as well as your overall cognitive function. So by simply getting up early and watching the sunrise, you can support your body's natural rhythms, improve your mood, and enhance your overall cognitive function.

Early morning sunlight is important because the natural blue light is received by the suprachiasmatic nucleus in the brain. The suprachiasmatic nucleus is the primary circadian pacemaker, signaling to the body that it's daytime and time to be awake. To receive the benefits, get at least fifteen to thirty minutes of sunlight exposure in the morning, such as during a walk or commute, without staring directly at the sun. This morning exposure can improve sleep at night.

Imagine going into a clock store with every clock is an alarm clock and they're on different schedules. It boosts a number of chemicals that need to be released early in the day. That morning sunlight coordinates all the cellular and organ systems of your body. And it sets a timer on some other clocks in the body, including the one that releases melatonin about sixteen hours later to make you sleepy and fall asleep easily. If you don't do it for two days or three days in a row, what happens is that morning increase in cortisol still happens, but it starts getting pushed out towards the afternoon. And that is strongly associated with depressive symptoms, anxiety, and sleeplessness at night, which then just makes it harder to function during the next day.

Essentials: Timing Light for Better Sleep, Energy & Mood | Dr. Samer Hattar
Guests: Dr. Samer Hattar
reSee.it Podcast Summary
Light regulates many body functions beyond vision, notably the circadian clock. The circadian clock is an approximate day; in constant conditions it drifts from the solar day. The central pacemaker in the brain is entrained by environmental light via intrinsically photosensitive retinal ganglion cells (ipRGCs) that project to mood and clock areas. Pattern vision blind individuals can still entrain via these cells. Morning light primes the system, and daylight intensity helps adjust the cycle, even on cloudy days. Three components influence sleep and mood: circadian timing, homeostatic drive (the longer you're awake, the more you need sleep), and direct light input from the environment. The tripartite model explains how light affects mood and appetite in addition to clock timing. Practical guidance: get 10-30 minutes morning light daily; if you miss days, jet lag: manage light timing and dim night lighting with red light.

Andrew Huberman: Don't Drink Coffee Right Away...(Do This Instead) And More Ways to Live Better
reSee.it Podcast Summary
The discussion centers on various practices to enhance mental and physical well-being, focusing on the impact of light exposure, breathing techniques, and exercise on our health. Light exposure is emphasized as a crucial factor influencing our sleep, mood, and overall performance. Bright light, particularly from sunlight, helps regulate our circadian rhythms by signaling the hypothalamus, which controls hormones related to alertness and sleep. The recommendation is to get outside for 5 to 20 minutes of sunlight exposure in the morning, ideally without sunglasses, to synchronize the body's internal clocks. For those who wake up before sunrise, using bright artificial lights can serve as a substitute. The importance of avoiding bright light exposure in the evening is also highlighted to promote better sleep. Breathing techniques, particularly cyclic hyperventilation, are introduced as a method to manage stress and increase resilience. This involves taking 25 to 30 deep breaths followed by a breath hold, which can help raise one’s stress threshold and reduce the sharp spike of adrenaline in stressful situations. Regular practice can lead to improved emotional regulation and a sense of calm. The conversation also delves into the significance of physical exercise, particularly resistance training and cardiovascular workouts, in maintaining cognitive function and overall health. Engaging in regular load-bearing exercises releases osteocalcin, a hormone that supports brain health, while cardiovascular activities enhance blood flow and lymphatic clearance in the brain. The recommendation is to aim for 150 to 180 minutes of cardiovascular exercise and three to four days of resistance training each week. Additionally, the discussion touches on the importance of impulse control and self-regulation. Techniques to enhance these skills include practicing "no-go" responses, which involve consciously resisting impulses throughout the day. This can help strengthen the brain's ability to manage reactions and improve decision-making. The role of breathing and vision in managing stress is also explored. Relaxed breathing can lower heart rates, while widening one’s field of vision can enhance situational awareness. Physiological sighs, which involve a double inhale followed by a long exhale, are suggested as a quick way to alleviate stress. Finally, the conversation concludes with reflections on personal success, emphasizing the importance of self-improvement, maintaining friendships, and understanding one’s role in the larger context of life. The speaker expresses a commitment to sharing knowledge about human biology to help others improve their lives and interactions.

Maximizing Productivity, Physical & Mental Health with Daily Tools
reSee.it Podcast Summary
Welcome to the Huberman Lab podcast, where we explore science-based tools for everyday life. I'm Andrew Huberman, a professor at Stanford, and today we'll discuss protocols for sleep, mood, learning, nutrition, exercise, creativity, and behavioral strategies, all backed by peer-reviewed literature. This episode serves as a review of previous topics covered in the podcast, including vision, hearing, balance, and mental health technologies. I’ve organized the science and protocols into a daily framework, as our biology operates on a 24-hour rhythm influenced by genes and proteins. I’ll share my daily routine as an example, emphasizing that you can adapt these protocols to fit your own schedule. The first step in my day is to wake up around 6 a.m. and record my wake-up time to determine my temperature minimum, which is crucial for understanding my body's rhythms. This temperature minimum occurs about two hours before I wake up and can help optimize my sleep and eating schedules. After waking, I engage in forward ambulation, or walking, which generates optic flow and reduces amygdala activity, thereby lowering anxiety. Research shows that walking can significantly decrease anxiety levels. I also ensure to get sunlight exposure first thing in the morning, which is vital for mental and physical health. Ideally, I spend 10 to 30 minutes outside to stimulate the melanopsin cells in my eyes, which helps regulate my circadian rhythms and promotes alertness. Hydration is another key aspect of my morning routine. I drink at least 16 ounces of water with a pinch of sea salt to replenish electrolytes lost overnight. I delay caffeine intake for 90 minutes to two hours after waking to avoid an afternoon crash, allowing my natural cortisol levels to rise first. I practice intermittent fasting, typically not eating until around noon. This fasting period increases adrenaline levels, enhancing focus and learning. I consume yerba mate or guayusa tea during this time, which also supports fat metabolism and cognitive function. After my morning work session, I engage in physical exercise for about an hour, alternating between strength training and endurance workouts throughout the week. Research supports that both types of exercise are beneficial for brain health and overall well-being. For lunch, I focus on a balanced meal with protein and vegetables, keeping carbohydrates lower to maintain alertness. After eating, I take a brief walk to aid digestion and reinforce my circadian rhythms. In the afternoon, I utilize non-sleep deep rest (NSDR) techniques, such as hypnosis, to enhance focus and relaxation. This practice helps me transition smoothly into my next work session without experiencing the typical afternoon slump. As evening approaches, I eat dinner, emphasizing starchy carbohydrates to promote serotonin production, which aids in sleep. I avoid high doses of melatonin supplements, preferring natural methods to enhance sleep quality. To prepare for sleep, I take a hot shower or bath to facilitate a drop in body temperature, which is essential for falling asleep. I keep my bedroom dark and cool, and I may use magnesium, apigenin, and theanine to support sleep onset. If I wake up during the night, I use NSDR techniques to help me return to sleep. Throughout the day, I maintain a consistent schedule, aiming to wake up and go to bed at the same time each day to support my circadian rhythms. In summary, I’ve outlined a daily routine that leverages scientific principles to optimize sleep, mood, and cognitive performance. I encourage you to adapt these strategies to fit your own life and explore the scientific literature for further insights. Thank you for your interest in science and for supporting the podcast.

"The FIRST HOUR In The Morning Is CRUCIAL!" (Why You're Always Tired) | Andrew Huberman
Guests: Andrew Huberman
reSee.it Podcast Summary
In a discussion about the importance of vision and its connection to the brain, Andrew Huberman emphasizes that the eyes are extensions of the brain, crucial for regulating alertness and circadian rhythms. The retinas send signals to the suprachiasmatic nucleus, the body's central circadian clock, which coordinates various bodily functions based on light exposure. Huberman highlights the significance of getting sunlight in the eyes shortly after waking to set the body's internal clock, which can improve sleep, mood, and overall health. He discusses the concept of optic flow, where movement through an environment can reduce anxiety and enhance emotional well-being. This principle underlies therapeutic techniques like EMDR, which uses eye movements to help process trauma. Huberman also addresses the negative effects of artificial light, particularly blue light, on sleep and mood, stressing that brightness, not just color, is critical during nighttime. Practical advice includes minimizing bright light exposure at night and using dimmer, lower lights in the evening. He encourages incorporating morning light exposure into daily routines, as it has profound effects on health. Huberman concludes by advocating for accessible, cost-free tools like light exposure and breathing techniques to enhance well-being, emphasizing the need for education and sharing of these practices to improve public health.

The discussion highlights the significant impact of light exposure on sleep and overall health. Dr. Seheult emphasizes the importance of optimizing sleep to prevent conditions like dementia, Parkinson's disease, and diabetes. He explains that to improve sleep quality, individuals must align their circadian rhythms by going to bed earlier and avoiding bright light exposure at night. Morning light exposure is crucial; ideally, one should seek bright natural light as soon as they wake up to help reset their circadian rhythm. Dr. Seheult notes that light intensity is measured in lux, with 10,000 lux recommended for effective circadian adjustment. He suggests spending time outdoors in the morning or using light therapy boxes if natural light is unavailable. The conversation also touches on the production of melatonin, which is primarily generated in the mitochondria from near-infrared radiation from the sun, rather than solely from the pineal gland. This melatonin acts as a powerful antioxidant, crucial for cellular health. The discussion further explores the effects of modern lifestyle choices on sleep, including the impact of caffeine, alcohol, and late-night eating. Dr. Seheult advises against consuming food close to bedtime and highlights the importance of a conducive sleep environment, including darkness and minimal light exposure.
