During sleep, your brain’s electrical activity goes through a five-phase cycle. A short afternoon catnap of 20 minutes yields mostly Stage 2 sleep, which enhances alertness and concentration, elevates mood, and sharpens motor skills.

Experimenting with this seed theory in 1963 proved it was accurate 70 percent of the time.
