If the body does not get enough deep sleep one day, it.The national sleep foundation advises that healthy adults between the ages of 26 to 64 need between 7 to 9 hours of sleep every night.Sleep stages 1, 2, and rem consist of light sleep, while 3 and 4 comprise deep sleep.People over 65 should also get 7 to 8 hours per night.Now that you have an understanding of the stages, we can discuss how much deep sleep is needed, and it's fairly straightforward:

This percentage is an important part of your sleep pattern.Although adults require 20 to 25 percent of their time asleep to be spent in rem sleep, for newborns the recommended time is 50 percent.Medical advice states that most people need 7 to 9 hours of sleep a night.And, during that, you'll probably get about 2 hours of deep sleep.Some studies have shown that your deep sleep should at least be 20% of your overall sleep.

A common misconception is that older people need less sleep.The older we grow, the more our sleep needs change.Hence as we grow older, the less deep sleep our body needs.The older among us get significantly less deep sleep than their younger counterpoints.Deep sleep should account for at least twenty percent of your overall sleep.

If you sleep longer than 20 minutes, you risk going into a deeper sleep and waking up groggy.
