You disrupt the circadian system. If you wake up before sunrise and daybreak specifically when it’s still dark, you want to maintain as much darkness as you can Easiest way to do this is to set the home up with minimal circadian lighting like red incandescents (specifically for
@zaidkdahhaj This is something I'm surprised I haven't seen more discussion of. We sleep 7-9 hours. 2-3 hours of darkness in the evening usually sets the signal where you're tired and it's time to sleep. That covers 10-12 hours. In winter, darkness is anywhere from 13-16 hours in the US,
@GestaltedApe You describe it well. Winter time is a game of endogenous melatonin production. Red and infrared light therapy, incandescents best used during this time. Cold exposure is a great tool as well https://x.com/zaidkdahhaj/stat...
@zaidkdahhaj Awesome. So just to clarify: the MyCircadian app tells me that, today, daybreak was 6:26am while Sunrise was 6:53am. Your saying as long as I can keep circadian disruption to a bare minimum before 6:26am, I can go outside and set my clocks right at daybreak? If that’s true I
@FDR_1932 Yupp, daybreak is when the official day begins for the body, so circadian alignment can be found with at least 15-20 minutes of exposure. The more, the better. If you can catch the sunrise and even UV-A rise, you’re cooking 🔥
@zaidkdahhaj Any recommendation regarding red light bulbs brands ? They're surprisingly hard to find where I live (🇫🇷)
@zaidkdahhaj Great post. I often wake up before sunrise. My practice, since I don’t have any specialty lights, is to keep the lights low and only dial up a reading light when needed. It has become my quality book time really. But never screens before sunrise
@zaidkdahhaj I get by in the dark when I wake up before sunrise 😅
This is why living in the tropics is so healing 1200-1400 hours of undisrupted Vitamin D making UVB light available every year
Dr. Glen Jeffery spent over a decade studying how light affects mitochondria. Blue LEDs impair them so severely, he won't get ethical approval to test it on humans. Red & infrared do the opposite—improving vision & significantly lowering blood glucose. Here's what he found: 🧵
Nope. A sign of blue light toxicity. But thanks for playing.
There are many narcissists and douche bags on X who love to pretend they own the rights a particular niche and therefore anyone posting in that niche is copying them yet also fail to acknowledge the giant minds who have come before them and realize the irony that they are the
