 how many hours of sleep do you need?


It is one of those facts that have gone pretty much unquestioned for decades: Get 8 hours of sleep every night.
It's a convenient starting point for adults, but not so much for older adults, children, and teens.
Now, the National Sleep Foundation has updated its guidelines on how many hours of sleep people need, adding age brackets and widening the acceptable ranges of sleep every night for most existing age groups. (The NSF also added a category of sleep times that isn't recommended, but may be appropriate for some people. A graphic that includes all of that is here.)
The new recommendations, based on age, look like this:
  • Newborns (0-3 months): 14-17 hours (range narrowed from 12-18)
  • Infants (4-11 months): 12-15 hours (range widened from 14-15)
  • Toddlers (1-2 years): 11-14 hours (range widened from 12-14)
  • Preschoolers (3-5): 10-13 hours (range widened from 11-13)
  • School-Age Children (6-13): 9-11 hours (range widened from 10-11)
  • Teenagers (14-17): 8-10 hours (range widened from 8.5-9.5)
  • Young Adults (18-25): 7-9 hours (new age category)
  • Adults (26-64): 7-9 hours (no change)
  • Older Adults (65+): 7-8 hours (new age category)

The recommendations were made based on "multiple rounds of consensus voting after a comprehensive review of published scientific studies on sleep and health," according to the foundation's statement.
"This is the first time that any professional organization has developed age-specific 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, in the statement. "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."


  1. Its no gain saying that many are not getting enough sleep which is affecting their health and as a matter of fact, many do not really know the normal amount of sleep they need to get to be healthy. this article has been able to educate us. Thanks for this piece.


  2. This is amazing because most people believe in 8 hours of night rest for everybody both old and young but the National Sleep Foundation has updated its guidelines on how many hours of sleep people need. We must follow this guidelines according to our age, as we all know that sleep is very vital to human.

  3. Not taking enough rest, has its own effect not to talk of not taking enough sleep. we must try and rest our eyes and most especially our body because they also need rest.

  4. 8 hours of sleep is just like a fact that is generally acceptable but with the new update night resting hour must be determined by age.
