Do people really manage to go more than a few days with less than 6-7 hours of sleep? I don't know anyone that does it. Also the article conveniently forgets how many near-isolated tribes with zero exposure to artificial light never sleep through the whole night, they wake up in intervals and often sleep very lightly because there's danger looming at all times. Sure, artificial light can be an issue, but if you practice self-restrain with screentime and get a lightbulb with a warmer tone for the late evening hours then your problem will be solved (if it even was caused by light exposure in the first place, and it usually isn't).
