Every individual has unique needs and preferences, and the answer to how much sleep you need is no different.

Nevertheless, the amount of sleep you need per night is largely determined by your age.

Average sleep needs by age (National Sleep Foundation)

  • Newborn to 3 months old: 14-17 hrs
  • 4 – 11 months old: 12-15 hrs
  • 1 – 2 years old: 11-14 hrs
  • 3 – 5 years old: 10-13 hrs
  • 6 – 13 years old: 9-11 hrs
  • 14 – 17 years old: 8-9 hrs
  • Young adults (18 – 25 years old): 7-9 hrs
  • Adults (26 – 64 years old): 7-9 hrs
  • Older adults (65+): 7-8 hrs

It’s not just the number of hours you spend asleep that’s important—it’s the quality of those hours. If you give yourself plenty of time for sleep but still have trouble waking up in the morning or staying alert all day, you may not be spending enough time in the different stages of sleep.
