Sleep and consolidation

Where learning is finished.

What sleep does

Memories are consolidated during sleep, particularly in the hours after learning. Sleep deprivation harms both encoding beforehand and consolidation afterwards.

  • A short nap after study measurably improves retention.
  • An all-night session trades tomorrow's memory for tonight's coverage.

Other basics

Exercise, hydration and breaks are not motivational advice; each has measurable effects on attention and retention. The unglamorous inputs matter.
