The peak of alertness and wakefulness, signaled by peptide release from sleep centers, occurs about an hour before bedtime.

“that desire to run around and clean the kitchen or organize things, or just a general feeling of internal anxiety, late in the evening, that's a natural blip that naturally passes after about 45 to 60 minutes.”

“But there's a brief blip, of release of peptides and other substances from the sleep centers in the brain, and the suprachiasmatic nucleus that the sleep center is this preoptic area, that if you wanna look that up. This preoptic area not far from the circadian clock that signals the peak of alertness and wakefulness about an hour, before bedtime.”
