The hidden dangers of blue light. Is blue light unhealthy for you?
"Blue light is the junk food of light", says Dr. Cohen, M.D. Is he right? Blue light comes from what we see as the "white light" from light bulbs, computer screens, smartphones, and pretty much inside most buildings. Health experts do agree it does cause harm while other still think it is not such a big deal. In short, we watched many hours of video and took a look at the research. VERDICT: you should ABSOLUTLY limit exposure to blue light, especially at night. We know you have probably heard of this before but we are revisiting this topic because it is so important, much more than thought before! Dr. Cohen, M.D. is starting to think with his new deep dive into the subject that blue light is a MAJOR MAJOR MAJOR issue, and a main link to chronic disease and general dis-ease more than poor diet and genetics alone. SO PAY ATTENTION! We know it is also linked to decreased athletic performance, high blood pressure, increased blood sugar, easier to force addiction and mind control through dopamine alterations, learning disorders and poor cognition, anxiety and mental illness, and even poor sleep and HRV. These are well known facts in the science and medicine world, yet blue yet continues to be placed on our computing systems and user interfaces! Indeed, you shouldn't look at blue light as much as possible. Problem, it is everywhere like we said! SUGGESTIONS: Try some blue light blocking glasses and replace light bulbs, to start. It's hard, we know, but try it out and see how you feel. Use your smartphone less. NOTE: don't get paranoid, please, it could be very easy to take this way to far and live in the dark with candles as some biohackers now are doing. Listen to us and just be smart about it and listen to your body. Maybe, still, try a detox for a few days and work back into blue light exposure. Set a balance. It is easy to get used to things bad for your health, such as blue light, overtime and not be aware of how it hurts you until you detox and come back to it.

Also look more into getting more RED LIGHT exposure to not just balance the negative effects, but to help your health and performance skyrocket. Learn more and get some research below on this.
- Bright blue light during meals: Exposure to bright blue light during meals can increase insulin resistance and peak glucose levels, especially in the evening.
- Blue-enriched light in the evening: Exposure to blue-enriched light in the evening can cause higher peak glucose levels compared to dim light.
- Blue light at night: Exposure to blue light at night can increase nonfasted glucose levels and sucrose intake in diurnal Sudanian grass rats.
- Light exposure during sleep: Light exposure during sleep may negatively affect metabolic regulation.
- Light pollution: Outdoor light pollution at night may be linked to diabetes.
Insulin resistance is the body's inability to adequately move glucose out of the bloodstream, resulting in a buildup of blood sugar. Over time, the excess blood glucose could result in increased body fat, weight gain, and a higher risk for diabetes. Kathryn Reid, senior study author and a research associate professor of neurology at Northwestern University Feinberg School of Medicine, says that while she and her colleagues do not understand why bright light has the effect that it does, using this light could manipulate metabolic function.

Abstract
Mitochondria regulate metabolism, but solar light influences its rate.
Photobiomodulation (PBM) with red light (670 nm) increases mitochondrial
membrane potentials and adenosine triphosphate production and may
increase glucose demand. Here we show, with a glucose tolerance test,
that PBM of normal subjects significantly reduces blood sugar levels. A
15 min exposure to 670 nm light reduced the degree of blood glucose
elevation following glucose intake by 27.7%, integrated over 2 h after
the glucose challenge. Maximum glucose spiking was reduced by 7.5%.
Consequently, PBM with 670 nm light can be used to reduce blood glucose
spikes following meals. This intervention may reduce damaging
fluctuations of blood glucose on the body.
