How Much Sleep Do You Need? – Learn what happens when you’re sleeping, how to determine your nightly sleep needs, and what you can do to bounce back from chronic sleep loss.
According to the National Institutes of Health, the average adult sleeps less than seven hours per night. In today’s fast-paced society, six or seven hours of sleep may sound pretty good. In reality, though, it’s a recipe for chronic sleep deprivation.

There is a big difference between the amount of sleep you can get by on and the amount you need to function optimally. Just because you're able to operate on seven hours of sleep doesn't mean you wouldn't feel a lot better and get more done if you spent an extra hour or two in bed.

While sleep requirements vary slightly from person to person, most healthy adults need between seven and a half to nine hours of sleep per night to function at their best. Children and teens need even more (see box at right). And despite the notion that our sleep needs decrease with age, older people still need at least seven and a half to eight hours of sleep. Since older adults often have trouble sleeping this long at night, daytime naps can help fill in the gap.

The best way to figure out if you're meeting your sleep needs is to evaluate how you feel as you go about your day. If you're logging enough hours, you'll feel energetic and alert all day long, from the moment you wake up until your regular bedtime
