The National Sleep Foundation has released an updated set of sleep recommendations after a review by a multi-disciplinary panel of experts from fields including sleep, anatomy and physiology, pediatrics, neurology, gerontology, and gynecology.
The literature review yielded revised sleep duration recommendations for all six children and teen age groups, and also resulted in the creation of two new age groups, younger adults (18-25) and older adults (65+).
“This is the first time that any professional organization has developed age-specific recommended sleep durations based on a rigorous, systematic review of the world scientific literature relating sleep duration to health, performance and safety,” said Charles A. Czeisler, PhD, MD, chairman of the board of the National Sleep Foundation, chief of sleep and circadian disorders at Brigham and Women’s Hospital, and Baldino Professor of Sleep Medicine at the Harvard Medical School, in a news release. “The National Sleep Foundation is providing these scientifically grounded guidelines on the amount of sleep we need each night to improve the sleep health of the millions of individuals and parents who rely on us for this information.”
The panel also decided on the addition of a new range, “may be appropriate,” in order to tailor sleep durations to individual needs. The ranges now include recommended, may be appropriate, and not recommended.
The updated sleep duration recommendations are as follows:
- 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)
