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.
And the deep, slow wave sleep state, which is when big, slow waves sweep through our brain. And now we realize that it cleans our brain. One of the things that those big, slow waves do is cleans our brain and does other really important things to restore us from a day of wakefulness.

And then we're also cleaning out through the deep slow waves of slow wave sleep. We're cleaning out all those misfolded proteins, unfolded proteins, and other things that get broken down and need to be rebuilt when we're asleep because of its use during wakefulness.

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.
