How light affects your sleep

It’s fascinating how our metabolic and hormonal regulation has evolved as a response to sunlight through our circadian rhythms

Working night shifts, would you rather work seven consecutive nightshifts every 6weeks, or 14 consecutive nightshifts every 12weeks? What would be the best alternative, health wise?

5 minute video simplified: Sun good in morning. Artificial lights bad at night.

Work hard at the day and u will sleep even under a projector at the night

This 110% tracks with my experience in that BRIGHT lights close to bed time have an near instant awakening effect on me. To the point that I turn off all the bright lights in my house and use dim, warm-shifted lamps in my rooms close to bed.

I listed to Peter Attia talk about sleep and it completely changed my perspective - sleep is the single most important thing we all take for granted

I loved this one. Does anyone know of a good summary/review of circadian rhythm science to date?

I sleep way better when all devices are off before I lay in bed... Although admittedly hard to always do

Who knows if it makes sense to wear a headband if photons are flying around. Or will the light still penetrate the skin? Can’t you fool the active sun during the day?🌞

Most undervalued sleep factor known to date in my opinion!
