Here’s How Much Experts Think You Should Sleep Every Night

The National Sleep Foundation releases new recommendations

A national panel of sleep experts released new recommendations Monday that call for more hours of sleep for most young people.

The National Sleep Foundation, a nonprofit aimed at promoting healthy sleep and safety, says the amount of sleep a person needs is highly variable and that some people need more than others. Still, the new hour ranges for each age group recommend more hours for infants, kids and teens:

  • Newborns (0-3 months ): Sleep range narrowed to 14-17 hours each day (previously it was 12-18)
  • Infants (4-11 months): Sleep range widened two hours to 12-15 hours (previously it was 14-15)
  • Toddlers (1-2 years): Sleep range widened by one hour to 11-14 hours (previously it was 12-14)
  • Preschoolers (3-5): Sleep range widened by one hour to 10-13 hours (previously it was 11-13)
  • School age children (6-13): Sleep range widened by one hour to 9-11 hours (previously it was 10-11)
  • Teenagers (14-17): Sleep range widened by one hour to 8-10 hours (previously it was 8.5-9.5)
  • Younger adults (18-25): Sleep range is 7-9 hours (new age category)
  • Adults (26-64): Sleep range did not change and remains 7-9 hours
  • Older adults (65+): Sleep range is 7-8 hours (new age category)

To come up with the new recommendations, the foundation put together a panel of 18 scientists and researchers from prominent medical associations in the United States and asked them to review over 300 studies on how much sleep is ideal. The panel then voted on how much sleep is appropriate at different ages.

Getting too little sleep and getting too much sleep are both unhealthy behaviors that can lead to a variety of consequences from grogginess to weight gain.
