Each stage cumulates to REM (rapid eye movement) sleep, and then restarts, completing one cycle. The first stage through REM takes about 90 minutes to complete, and adults typically need to complete at least four or five sleep cycles per night, or 6 to 9 total hours of sleep.

It's normal to take 10 to 20 minutes to fall asleep once you climb into bed (this is called sleep latency). If it takes more or less time than that, then your body may be trying to tell you something.

The time it takes you to fall asleep is known as sleep latency. If you fall asleep before or after the typical 10 or 20 minutes it generally takes, you may have an underlying sleep condition. One study found that your sleep quality will decrease if it takes you longer than a half hour to fall asleep.

The answer depends on whom you ask, but in general, experts recommend keeping naps short: 10 to 30 minutes for a power nap, and no more than two hours for longer naps. Any more than that and nappers risk having trouble getting sufficient sleep (at least six hours) overnight.

One of the most frequent questions that I get is, “How long does it take to become an early riser?” It only takes your body 4–5 days of waking up and going to bed at the same time to adjust to the new schedule. It works even if it's a big change, like moving in a different time zone.

If the body does not get enough deep sleep one day, it will compensate the next time it can get sleep by quickly moving through the cycles to reach the deepest levels of sleep faster and stay there longer. However, if the person regularly does not get enough deep sleep, this may start to affect the brain.

But five hours of sleep out of a 24-hour day isn't enough, especially in the long term. According to a 2018 study of more than 10,000 people, the body's ability to function declines if sleep isn't in the seven- to eight-hour range.

That being said, catching up on a missed night of sleep isn't quite the same as getting the sleep you need in the first place. When you catch up, it takes extra time for your body to recover. According to a study from 2016 , it takes four days to fully recover from one hour of lost sleep.

It takes 4-6 hours for the memory foam to expand 90% and could take another 4-6 hours to get close to full expansion. It is recommended to wait 24 hours before sleeping on it, but don't worry if you can't.

On average, light sleep will take up about 50 to 60 percent or more of your night. “Whether you get more or less light sleep isn't really going to affect how you feel too much, because it's just whatever time is left that's not spent in deep sleep or REM,” says Grandner.
