An expert panel that examined data from 320 studies is recommending new guidelines on how much sleep people should get. The guidelines are based on age, ranging from newborns (who need 14 to 17 hours of sleep per day) to adults aged 65 and up (7 to 8 hours per day).
These are the sleep-time recommendations from the National Sleep Foundation expert panel:

* 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).
