Is 7 hours of sleep enough

How Many Hours of Sleep Do You Need?

The National Sleep Foundation advises that you should get different amounts of sleep based on your age.¹ As we get older, we generally need less sleep, though individual needs may vary.

But how much sleep you need every day depends on many factors, and recommended hours of sleep by age is only one piece of the puzzle.

Your sleep schedule should be personalized to what you need and prefer, but research suggests you should generally aim for the recommended range for your age group.²

If you’re trying to fix your sleep schedule or wondering if four hours of sleep is enough (spoiler: it usually isn’t), consult the sleep chart by age below to determine how much sleep you should aim to get each night.
