The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.
we've had no pressure to get rid of it meaning like all the pressure that would get rid of it that we discussed you know the inability to get food while you're sleeping the inability to find a mate the inability to protect yourself the inability to care for your children we resisted all of those things
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.

Sleep is the most idiotic of all things in terms of a creation from Mother Nature. You know, you're not finding a mate. You're not reproducing. You're not eating. You're not caring for your young. And worse of all, you're vulnerable to predation. So on any one of those grounds, sleep should have been strongly selected against in the course of evolution. The exact opposite is true. Every species that we've studied to date sleeps.
10 minutes of bright outdoor light within the first hour of waking anchors the circadian phase and improves sleep onset that night.
Morning sunlight exposure shifts the cortisol awakening response forward, improving daytime alertness.
Long-term morning sunlight reduces age-related macular degeneration risk.
Sleep regularity predicts all-cause mortality more strongly than sleep duration.
Tracking deep sleep on a wearable accurately reflects EEG-measured slow-wave sleep.
Caffeine has a half-life long enough that consumption after 2pm measurably degrades deep sleep in slow metabolizers.
