He recommends viewing low angle sunlight, per the episode.
Caffeine works by blocking adenosine, he explains.
He introduces NSDR as a reset for alertness.

How can you sleep better and feel more alert when awake?

Huberman explains that sleep and wakefulness are governed by a circadian clock and by adenosine, the sleepiness molecule caffeine blocks. He says viewing sunlight early in the day and again near sunset, when the sun is low, sets the clock through cells in the eye. He also describes non-sleep deep rest, or NSDR, as a way to restore alertness.
