Briefly, what constitutes deep sleep? Deep sleep, for example, is the stage of sleep you need to feel refreshed when you wake up in the morning. Unlike rapid eye movement (REM) sleep, deep sleep is when your body and brain waves slow down. It's hard to wake from deep sleep, and if you do, you may feel particularly groggy.

On top of everything, does exercise increase deep sleep?

What percentage of deep sleep is normal?

How much deep sleep should you get? In healthy adults, about 13 to 23 percent of your sleep is deep sleep. So if you sleep for 8 hours a night, that's roughly 62 to 110 minutes. However, as you get older you require less deep sleep.
