Abstract

A short afternoon nap significantly improved procedural memory in 34 young healthy subjects.

  • Naps consisted mainly of sleep stage 2, with some slow wave sleep and rapid eye movement sleep.
  • Declarative memory showed no improvement from napping, although females performed better than males regardless of napping status.
  • No significant differences in cortisol secretion or alertness were observed between the nap and wake groups.
  • The findings suggest that short naps may specifically enhance procedural memory consolidation.
