Sleep and Naps

Sleep Info

Good sleep health is important for our health and wellness. Sleep is essential for the body and mind to recharge, it is the time when our body systems reset and recover. Young adults need around 7 to 9 hours of sleep each night.

Nap Length

Napping is the next best thing if you can't get enough sleep at night! Ever wonder the best length of time for a nap?

  • 10-20 minutes: Ideal napping time. Boosts alertness and energy. This length limits you from entering deep sleep.
  • 30 minutes: Not so ideal. This may cause a groggy feeling for 30 minutes before you actually feel better from the nap (and make better decisions)
  • 60 minutes: Best for facts, faces and names. This nap helps improve memory and includes the deepest type of sleep. Be ready for some grogginess though.
  • 90 minutes: Full REM cycle. This nap is a full cycle of sleep and helps with improved emotional and procedural memory and creativity. This length usually has less grogginess.

Nap Stats

  • 34% of adults in the U.S. say they take a nap on a typical day.
  • Ideal nap time is 1pm-4pm.
  • Best nap length? 10-20 minutes.
  • A person who dreams during a short nap is likely sleep-deprived.
  • Naps are better than coffee at helping with memory (caffeine decreases memory function).
