EMFs have been on the main stage thanks to an incredible investigation from @sunlightis.life about the magnetic field exposure from an electrical substation next to the San Francisco 49ers facilities potentially being the reason behind their league leading injury rate. As someone who has researched the biological impact of EMFs for years now, here are my key findings and thoughts: • ELF Magnetic Fields have been shown to increase risk of cancer + risk of miscarriage at very low levels (3-4mG) • In 1990 the EPA recommended ELF mag fields be classified as a “probable carcinogen”, but this was reversed at the last minute • The Niners have practiced at this facility since the late 80s, but the substation went through a 2000% capacity increase in 2014 when Levi Stadium was built • Man made electromagnetic fields even at low intensities can interfere (EMI) with normal cellular signaling and lower the Signal to Noise Ratio (SNR) • Athletic movements are rooted in fascia, which is a collagen-water matrix that has electromagnetic properties such as piezoelectricity and charge transfer • Since 2014 (year injuries started skyrocketing) our electromagnetic environment as a society has drastically changed (more artificial lights, screen time through the roof, RF-EMF exposure, etc.) There is likely no way to prove actual causation of an electrical substation’s magnetic field exposure causing an increase in soft tissue injuries given the current body of evidence, however doing investigative work such as Peter Cowan has done opens the possibility of that being real in the future. It also brings awareness to the overall impact of our electromagnetic environment on our health, which is in my opinion a severely under-discussed topic because it deals in a lot of inconvenient truths. Comment “EMF” and I’ll send you a link to my in depth substack article on this topic which dives way deeper than this video and considers all of the potential reasons Niners players have a higher injury rate.

Modern “energy efficient” low emissivity windows are a large problem for our health because they block out biologically important Near-Infrared (NIR) and Ultraviolet-A (UVA) light. It takes the full spectrum sunlight and distorts it to being very dominant in the visible wavelengths. This is problematic, because low energy near-infrared light balances out the oxidative response in our cells when exposed to high energy visible (blue/violet) light. A large reason you feel so drained being inside all day is because there is little to no infrared light. We need more warmth, not less in our cold modern world. Best Windows for Transmissivity : Low Iron Glass, Acrylic Or just open your windows as much as possible for full spectrum light + negatively ionized fresh air 🌞 great image from @sarahkleinerwellness on low-E window light transmissivity (can vary by window)

The 5G towers down the street aren’t ideal, but the devices (esp. our phones) we keep close to us and use every day are what we should pay more attention to. We rely on our phones constantly, and getting rid of them isn’t realistic. Here’s what you can do instead: 1) Turn off 5G in your settings. 2) Only use Wi-Fi OR Cell Data —> Never both. Ideally Wi-Fi and rest of your phone on airplane mode. 3) Keep your phone on airplane mode whenever you carry it on your body. 4) Avoid holding your devices next to your brain or reproductive organs. Use headphones or speaker for phone calls, use a pillow or a table to put separation from a laptop. 5) Keep your phone and all devices out of the bedroom (and unplug Wi-Fi) for better sleep quality. 6) When you turn your cell data back on, give it 5-10 seconds to reconnect away from your body (this is when RF-EMF output is the highest). Using technology intentionally is the best way to reduce RF-EMF exposure and minimize the stress it may have on your biology. Comment “EMF” and I’ll send you my full two hour podcast with Alec Zeck, @d_alec_zeck, where we dove deep into practical tips about light, EMFs, and our mission @daylight.kids.

In my opinion a candle or a campfire is the gold standard for the healthiest light to use at nighttime. Fire is extremely warm (<2000K), dim, and contains a vast amount of red + infrared light. This is the signal humans have used to wind down for all of existence. A warm incandescent is almost identical to a candle or campfire light spectrum and that is why I think they are the best option for night time lighting in a modern world. Red LEDs are cool and have been the mainstay recommendation in the biohacking world for years now. However I am not a fan of purely red light, the lack of infrared, the high flicker, or the high price point for a higher quality version. This is why we have made low wattage, ultra warm and Edison style incandescents (2100K) @daylightco - so everyone can access a low cost and high quality nighttime lighting. The bulbs sold out in 3 days when we launched but are now back in stock! COMMENT “BULBS” and I’ll send you the link to grab a pack 💡

The process of traveling is unfortunately one of the most detrimental things you can do to your health, and the EMF exposure certainly plays a part in that. In my opinion the airport RF exposure and the airplane magnetic field exposure due to the turbines and onboard power distribution system are my biggest EMF concerns. Unfortunately there isn’t much you can do to shield magnetic field exposure, but the good thing is unless you are on a long haul flight it really isn’t worth stressing about. I need to do more measurements to confirm this, but from my initial readings + a paper I found the lowest magnetic field exposure on airplane would be in the aisle seats towards the back of the plane. Stay tuned for more confirmation on this as I have a few flights coming up + more tips on mitigating the stressors of travel. PS the airport scanner is much less of a worry than the phone in your pocket.

Whole food form of PUFAs, especially Omega 3s, are a superfood in winter time, because they uncouple your mitochondria and influence metabolism to be better suited for a colder environment. Fat oxidation will be up-regulated, and the ability for your body to produce heat will also increase. The concern of high oxidative/inflammatory load of PUFAs is far less of a concern in winter time because there is less heat + light available (drivers of oxidation in unstable fats). Now this doesn’t mean you should be guzzling highly processed canola oil for breakfast…but rather thinking about nutrient dense whole food fat sources such as: - fatty fish (salmon, sardines, mackerel, etc.) - pastured lamb + pork - nuts (pine nuts, walnuts, pecans, etc.) - bone marrow Getting cold, eating higher fat, and uncoupling your mitochondria will also allow your body to produce more light internally (infrared + weak UV). Fascinating new research is just starting to scratch the surface of our complex metabolic + respiratory cellular processes. The importance of DHA especially in winter can not be understated. Regardless, this is not an Rx for only eating fat (keto) and an absurd amount of PUFAs this winter…it is simply a perspective to consider the importance of seasonality + cyclicality in our diet based on geographical location. Metabolic adaption is a flex of a healthy individual, why not give it shot this winter. There is a reason cold water fish have higher PUFA/DHA content, there is a reason why nuts are available in late fall. Embrace winter - the greatest season for deep thinking + character development - to get the full human experience 🐟 ❄️ COMMENT “PUFA” and ill send you my free substack article about thriving in winter time through uncoupling your mitochondria.

You don't need to supplement Vitamin D to feel good in the winter. In fact it could do more harm than good. You should: 1. embrace cold 2. eat seasonally 3. prioritize outdoors time 4. embrace restorative cyclicality

benefits of living a more feral lifestyle: microbiome diversity that is >3x higher than the upper end of the reference range. i think im going to keep walking barefoot, drinking unfiltered mountain stream water, eating raw meat and avoiding normal personal care products.

Light. Health. Matters.

Night shift mode, red screen filters, and blue light blocking glasses are all imperfect band aid solutions to fix something that is disruptive at the core hardware level. Also, do you really think Apple and Google want you to stare at your phone less at night time? The only way to fully fix night time screen use is to build a better solution from the ground up. That’s what we’ve done @daylightco Years of development, hassling suppliers with no leverage to make custom switches that are a net benefit to the end user. That’s what it takes. And we’re just getting started…

Here’s what happens when you put tin foil on your WiFi router.

Screen flicker is one of the most underrated stressors to our body.

how to never get seasonal affective disorder again: - shift diet to be higher fat/carb ratio - get cold (turn thermostat down) - spend as much time outside as possible - never miss a sunrise - sleep 8hrs/night - don't exercise after sunset - change to incandescent bulbs

"Teslas are an encasement of cancer causing frequencies." Is driving in a Tesla extremely dangerous for your health? My thoughts, breaking it down to the actual technological differences between an EV and an ICE vehicle ⬇️

The amount of RF EMFs in the wilderness = ZERO If you ever want to understand what it feels like to be free of these stressful artificial inputs, spend the weekend camping off grid. The ultimate nervous system reset.

A friendly reminder that incandescents are the healthiest lights you can buy. Rich in warm and biologically important near infrared light. No pulsed flicker. Purely analog. With the long night approaching, it is officially incandescent season.

Wishing all the best to Chris Williamson, but you seriously cannot get away with pushing your body to the degree he is when in such a toxic environment. My full thoughts ⬇️ No IV or supplement is going to fix the fact that his environment, especially from an electromagnetic perspective, is draining him and keeping him in Cell Danger Response. Tinnitus is a hallmark symptom of Electro-hypersensitivity(EHS). He needs a tech detox, nature filled reset and then a very purposeful path forward in lifestyle habits to get his body back into a healing state. I hope that happens.

How bad are the EMFs coming from Starlink compared to a normal Wi-Fi router? In my opinion, if you have an optimized setup out in the wilderness, much better. Here's why:
