The St. John Breber School in Niles, Illinois, a suburb of Chicago, was the subject of a study when, in 1963, the Communicable Disease Center of the U. S. Public Health Service in Atlanta reported an unusually high rate of leukemia among the children attending the school—the highest rate of any school in the country, five times the national average. Numerous national cancer agencies, both public and private, investigated this situation, yet no positive explanation for the unusually high leukemia rate was found. Until an explanation is available, every possible clue should be explored, and with this in mind, a visit to the school was conducted to learn interesting details not previously uncovered. From records reviewed, it was learned that the leukemia cluster developed shortly after the teachers in two classrooms were transferred to the school and began to keep the curtains closed at all times because of glare from the large areas of glass used in constructing the building. This practice effectively meant keeping the high-intensity fluorescent lights on continuously. At the time of the high leukemia incidents, the lighting used was the Deluxe Warm White fluorescent tube, described as the pinkest of the standard tubes used for ordinary lighting purposes. Further review of the available records showed that the leukemia cluster emerged in this pattern after the two teachers were assigned to these rooms and began the routine of keeping the curtains closed regardless of weather conditions and leaving the fluorescent lights on all the time. The cluster’s disappearance occurred shortly after these same teachers were transferred to other schools. Coincidentally, during the same period, all of the Deluxe Warm White tubes were old and were replaced with Cool White tubes, which, while not a full-spectrum type of tube, do represent less distortion than the Deluxe Warm White when compared to natural sunlight. These observations suggest a temporal association between the peculiar classroom environment—closed curtains reducing exposure to outdoor light, combined with continuous use of a particular type of fluorescent lighting—and the occurrence of leukemia in this school cohort, with a noted reversal following the shift to different classrooms, staff, and newer lighting.

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.

A sleep-deprived individual can develop insulin resistance in just seven days. There is a direct correlation between sleep deprivation and the potential to develop type 2 diabetes. According to the speaker's experience consulting in 14 metabolic clinics, every overweight or obese patient with metabolic syndrome, weight gain, health issues, cholesterol issues, or type 2 diabetes also had sleep problems.

The video argues that removing LED bulbs from homes is important because LEDs contribute to health issues on a daily basis. It contrasts LEDs with traditional light sources, stating that the sun, fire, and incandescent bulbs emit infrared light, which “actually boost cellular energy and repair.” In contrast, LEDs are described as exposing people “only to blue light.” The speaker cites studies claiming that prolonged exposure to this blue light accelerates aging, disrupts neurotransmitters in the brain, and impairs mitochondria. These effects are presented as reasons why many people feel constantly tired and drained when indoors. Another point made is that LED bulbs flicker at high speeds that are “too fast for your eyes to notice, but enough to stress your brain and your nervous system.” This flicker is presented as an additional risk associated with LED lighting. To mitigate these issues, the speaker shares a personal precaution: wearing blue light blocking glasses “anytime I can’t control my environment and the lighting.” The overall message emphasizes a link between LED lighting and adverse health effects, drawing a contrast with traditional light sources and recommending the use of protective eyewear in situations where lighting cannot be controlled.

The shorter your sleep, the shorter your life. The World Health Organization considers night shift work, where you lose sleep, a possible carcinogen. Every spring when we lose an hour of sleep, there's a 24% increase in heart attacks. Every fall, when we gain an hour of sleep, heart attacks decrease by 21%. Sleep is connected to our health in a massive way, and you need seven to eight hours of sleep. Turn your phones off hours before bed. Use blue light glasses if you have to. Get away from the screens and chill down. Maybe read before bed, but don't get stimulated.

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.

The speaker describes a new device used to measure the spectrum of light, noting that under full sunshine it reveals all seven colors—“just like the rainbow”—and that this natural spectrum is straightforward. When measuring incandescence, the speaker highlights a “beautiful red hue” and claims there is “really none of the other stuff to make you go blind,” implying that incandescent light presents a safe, simple spectrum in comparison to other sources. The speaker then discusses LEDs, stating that they are “super weird to have LEDs” because they “cause blindness, cataracts, dizziness, headaches, fatigue,” and references “that color spectrum” as part of the issue. Fluorescence is described as being almost identical to LEDs in this respect. The speaker also mentions “full moonlight” in this context, implying a comparison between the spectral qualities of LEDs/fluorescent light and moonlight. A key point emphasized is that LEDs and fluorescent bulbs seem to mimic moonlight, which the speaker notes as a source of behavioral or perceptual effects, claiming that this similarity to moonlight is what contributes to people going nuts. The overall message centers on a contrast between the spectra of different light sources—sunlight with its full seven-color spectrum, incandescence with a prominent red hue and fewer problematic elements, and LEDs/fluorescent lighting with problematic health and perceptual effects and a moonlight-like quality.

Speaker 0 says that at the lows people are buying incandescent bulbs because of a new ban, and it is important to stock up on these bulbs. Incandescent bulbs are described as very natural to our eyes, and it is emphasized that one should put incandescent bulbs into the home and not LEDs. The speaker claims the problem with LED lights is that they burn out the back of the eye, which “causes cataracts,” and that smart bulbs and devices connected to WiFi ping radiation to the skull while plugged in. Therefore, the advice is to avoid anything with LED and anything that's smart—specifically, smart remote, smart sensors, smart plugs, and smart bulbs. The speaker notes that these are all LED lights installed in the hardware store. Additionally, the speaker urges avoiding anything with Bluetooth built in because Bluetooth operates at the same frequency as a microwave. The overall message is that many marketing tactics push the new bulbs, but one should stick to incandescent bulbs.

Artificial blue light from screens tricks the body into thinking it's daytime, disrupting sleep patterns. When it gets darker, the body produces melatonin, a sleep hormone. Artificial light blocks melatonin production, preventing the body from sending signals to cells to release it. Therefore, avoid screens like TVs, smartphones, and computers before bed.

Melatonin, produced by the pineal gland, is the body's natural sleep aid. As darkness increases, melatonin levels rise, signaling the body to prepare for sleep. Blue light from digital devices can suppress melatonin production by tricking the brain into thinking it's daytime. Switching off screens an hour or two before bed may improve sleep. A good night's sleep is a cornerstone of health, so respect melatonin.

A sleep-deprived individual can develop insulin resistance in just seven days, indicating a rapid path to potential type 2 diabetes. There is a direct correlation between sleep deprivation and type 2 diabetes. According to the speaker's experience consulting in 14 metabolic clinics, every overweight or obese patient with metabolic syndrome, weight gain, health issues, cholesterol issues, or type 2 diabetes reported having sleep problems.

In the discussion, LED light bulbs are described as toxic and advisable to carry a warning label. The speaker presents two specific warnings about LED lighting: - Warning 1: The flicker effect. LED lights flicker at a frequency that is unperceptible to the eye but claimed to be brain-disrupting, potentially leading to sleep disturbances, migraines and headaches, brain fog and fatigue, and harm to the health of the eyes. - Warning 2: Unhealthy levels of blue light. LED lights are said to emit high levels of blue light, which can disrupt the circadian rhythm and affect mood. The speaker asserts the following factual contrasts to incandescent and halogen lighting: LED lights drain energy and life from the body, whereas incandescent and halogen lighting contain a full spectrum of light and infrared light that supposedly adds energy and light to the body, making people healthy. A call to action is issued to switch out lighting, with an optimistic note that the 2022 ban on incandescence and halogens might be reversed in 2025. The message emphasizes that these symptoms and effects can be life-altering for some individuals, and it ends with a request to share the video.

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.

Exposure to screen type light between the hours of 11PM and 4AM activates a specific circuit in a brain area called the habenula that lowers dopamine and creates a sense of disappointment. So it's pro depressive. That's straight from the discussion that followed: “from 11PM to 4AM, if you're on your phone, if you're looking at a TV or iPad or screen consistently, it's going to make you more depressed.” It was noted that “in theory, yes,” but in practice you would have to do that pretty consistently. The conversation also clarified that it’s the brightness of light, not the color of the light, that matters. Measures to mitigate include dimming it way, way down, or wearing glasses or using biohacking stuff. The claim was reiterated: “the studies by multiple groups are showing that from 11PM to 4AM, if you're on your phone… it’s going to make you more depressed.” The response added that there isn’t just one exposure; rather, “it's not like one exposure,” and “it's going to dim dopamine” or “blunt dopamine.”

You realize you can extend your life just by fixing your sleep. If you're getting less than five hours of sleep, your risk for dying goes up by like twelve percent. So the sleep is a very powerful predictor of all cause mortality. And I'm not just talking about the amount of sleep, I'm talking about the quality of sleep.

Let's talk about the bad effects of light. Nowadays because of screens and artificial light, we have access to light at times of day and night that normally we wouldn't. The longer you've been awake, the more sensitive your retina and these cells are to light. You want as much light as is safely possible early in the day, morning and throughout the day, including blue light. So take those blue blockers off during the day unless you have a real issue with screen light sensitivity and you want as little light coming into your eyes artificial or sunlight after say 8PM. And certainly you do not want to get bright light exposure to your eyes between 11PM and 4AM.

Blue light from devices, TVs, and indoor lights signals to the brain that it is daytime. Even when it's dark outside, this light exposure prevents the brain from increasing melatonin production, which is necessary for rest and sleep. The light tells the brain not to produce melatonin because it perceives daylight, hindering the body's natural preparation for sleep.

Mark Baker, founder and president of the Soft Lights Foundation, and Clayton (Speaker 0) discuss the health and societal concerns around LED lighting. Baker argues that LED lights are devastating to health due to their blue-rich spectra, prevalence in night environments, and the resulting impact on sleep, mood, circadian biology, and overall well-being. He describes personal experiences that motivated his activism, including a mental breakdown linked to LED exposure and a subsequent shift to full-time advocacy. Baker explains that LEDs are now ubiquitous: LED headlights in cars, blue-rich LED streetlights, general-service LED lamps in homes, and intense LED indicators on appliances. He notes that emergency vehicles with flashing LEDs are also problematic for some people. He acknowledges that the issue feels overwhelming to many, including bureaucrats, which adds to the difficulty of solving it. The conversation delves into Baker’s backstory. In the mid-2010s, as high-powered LED lights proliferated, he noticed blue-rich headlights and 5,000 Kelvin streetlights that disrupted his psychological wellbeing. Living in California, he experienced intense lighting at night from apartment windows and, after attempting to contest changes with city officials, suffered a severe mental breakdown when his school district refused to turn off the LEDs. This led to hospitalization and redirected his career toward advocacy, studying physics, government regulation, and organizing with others suffering similarly. Baker emphasizes that many people experience LED-induced sensitivities: migraines, epileptic seizures, sleep disruption, and even suicidal thoughts for some. He notes that individuals with astigmatism report driving difficulties due to LED headlights. He characterizes the public as having diverse responses: some people are highly sensitive to LEDs, others notice little to no effect. He frames the community as “canaries in a coal mine” for broader environmental and health impacts. The discussion covers the science of light. The body has photoreceptors beyond the eyes, including in skin and tissues, with blue wavelengths around 450 nanometers linked to circadian regulation. He asserts that artificial light at night interferes with melatonin suppression and cellular repair processes, thereby increasing health risks. He argues that the spectral distribution of many LEDs, with a prominent spike in blue light and no infrared, contrasts with incandescent light, which has a warmer, red-yellow spectrum and includes infrared. He maintains that LEDs are further from natural light than incandescent sources and that this spectral shift affects mood, sleep, and health. On policy and regulation, Baker critiques the 2005 Energy Policy Act, which directed the Department of Energy to pursue solid-state lighting and set a minimum luminous efficacy of 45 lumens per watt. He contends that the DOE did not coordinate with the FDA to ensure safety standards, so LEDs entered markets without assessing flicker, color temperature, or overall quality. He suggests this failure contributed to a mismatch between efficiency goals and health outcomes. He calls for reintroducing safe, healthy lighting and undoing “the effective ban on incandescence,” arguing that incandescents were healthier and that the current LED emphasis ignores health impacts. Baker discusses practical implications for sleep and daily life. He recommends reducing exposure to night-time LED lighting, using warmer color temperatures (around 2,700 Kelvin or lower), and installing measures to limit blue light in bedrooms. He notes that even skin exposure to light and non-visual photoreceptors can affect sleep. He mentions that some LEDs are being redesigned to imitate incandescent light, including “natural light” LEDs with broader spectral distributions and devices that incorporate infrared light to soften nighttime exposure. He also highlights the challenge of modern fixtures that integrate LEDs into fixtures rather than as replaceable bulbs, complicating the shift away from blue-rich lighting. The Soft Lights Foundation provides resources at softlights.org, including a campaign to ban blinding car headlights and an LED incident report for the FDA. Baker mentions a Change.org petition with tens of thousands of signatures, a database of incident reports to push regulatory action, and a resources section with scientific articles. He encourages joining the Ban Blinding LEDs Facebook group and engaging with regulatory and legal efforts (e.g., lawsuits) to address LED-related health concerns. In closing, Baker argues the system resists change, driven by arrogance, incompetence, negligence, and financial incentives, but denies a conspiratorial killing intent. He invites listeners to learn more, sign petitions, and consider environmental and health impacts when choosing lighting options.

Mark Baker, founder and president of the Soft Lights Foundation, argues that LED lights are devastating to health and leverages his personal experiences to advocate for change. The interview explores how blue-rich LED lighting has become ubiquitous, including car headlights, streetlights, household general service lamps, and indicators on appliances, as well as assorted night-time sources like smoke detectors and alarm indicators. Baker describes his awakening to the issue in the mid-2010s. While teaching in California, he noticed blue-rich LED headlights and 5,000 Kelvin LED streetlights that disrupted his psychological well-being. An apartment on the second floor was flooded with intense light, leading to a mental breakdown when his school district refused to switch off the lights. This event redirected him from teaching to full-time advocacy, involving him in learning the physics of light, government regulation, and connections with others suffering from LED exposure around the world. He recounts that many people initially resist confronting LED issues because the problem feels overwhelming. He notes the pervasiveness of LED lighting—car headlights, streetlights, household lamps, and even emergency vehicle lights—and emphasizes that bureaucrats often feel overwhelmed, which can impede action. He describes a community of people who report a range of sensitivities and health effects linked to LED exposure, including migraines, epileptic seizures, and, in some cases, suicidal ideation, as well as driving difficulties for people with astigmatism. He frames the community as “canaries in a coal mine,” highlighting that different people have different sensitivities and that some may be unaware of how LED lighting affects their sleep or mood. The discussion highlights that LED lights emit a spike at blue wavelengths, particularly around 450 nanometers, which is tied to regulating circadian rhythms and wakefulness. Baker argues that artificial light at night interferes with melatonin suppression and cellular repair processes, thereby disrupting sleep and health. He asserts that the natural night environment should be preserved as much as possible and that LEDs, with their spectral distribution and lack of infrared, diverge significantly from natural light. On how LEDs work, Baker explains that LED stands for Light Emitting Diode, a solid-state lighting technology that emits photons through an electronic process, not combustion. He highlights issues such as flicker due to drivers, directional light emission, and the spectral power distribution across wavelengths. He notes that the Department of Energy acknowledged the directional nature of LED light and, at one point, eliminated infrared light as waste heat; later, scientists recognized the benefits of infrared light for certain applications. He contends that the shift from incandescent to LED lighting was pursued for energy savings but without proper standards for safety, flicker, or quality, and without adequate evaluation by the FDA, which the law required to collaborate with the DOE. Baker traces the policy trajectory: the 2005 Energy Policy Act directed DOE to evaluate solid-state lighting, and by 2007 the minimum luminous efficacy standard (45 lumens per watt) effectively phased out incandescent bulbs. He argues that the DOE did not ensure safety or quality standards, focusing only on efficiency. This, he claims, led to widespread adoption of LEDs without comprehensive health safeguards and without FDA oversight. Regarding sleep and nighttime exposure, Baker cites evidence that even tiny indicators and devices in bedrooms—smoke detectors, nightlights, routers, and other LED indicators—can interfere with sleep and circadian rhythms. He notes that skin exposure to light also influences physiological processes, expanding the scope beyond ocular effects. He stresses the potential health risks associated with long-term exposure, including cancer, diabetes, and mood disorders. Regarding solutions, Baker argues for reintroducing incandescent technology and reducing reliance on LED-heavy lighting, while pushing for FDA evaluation and regulation of LED products. He mentions practical adjustments, such as choosing lower color temperatures (around 2700 Kelvin or lower), avoiding flicker, and using alternative bulbs for fixtures where possible. He describes programs and campaigns by the Soft Lights Foundation, including a petition against blinding car headlights and a system for LED incident reporting to the FDA. He points to resources on softlights.org, a campaign to stop blue-rich LED headlights, and a Facebook group called Ban Blinding LEDs for community support. For actionable guidance, Baker encourages individuals to minimize night-time LED exposure in their environments, shield streetlights when possible, switch to warmer lighting, and seek regulatory change to allow safer lighting options, including incandescent or incandescent-inspired LEDs with infrared components. He invites people to learn more through Soft Lights Foundation resources and to participate in advocacy and reporting efforts.
