Additionally, some studies have shown that a very hard workout or rigorous exercise can increase deep sleep or help your body to consolidate it. It can be difficult to impact a specific sleep phase, but working on improving your overall sleep should help you to get more quality deep sleep. A 30-year-old may get as much as 2 full hours of deep sleep, while people over 65 may get only 30 minutes, or sometimes none at all. The older among us get significantly less deep sleep than their younger counterpoints. There is no specific requirement, but it appears that younger people need, and get, more deep sleep-between 1-2 hours. The good news is, if you’re getting 7-9 hours of sleep each night, you’re probably getting the correct amount of deep sleep. Therefore, most people probably get around 1.5-2 hours of deep sleep. Most sleep cycles last about 75-90 minutes, which means that in a typical 7-8 hour night of sleep, a person would go through about 4 sleep cycles. This stage of sleep is also when important hormones, such as the human growth hormone, are released, leading to benefits such as increased blood supply to muscles, growth, and repair of tissue and bones, and energy restoration.įor the average sleeper, the sleep cycle is broken up as follows: It increases long-term and short-term memory, and aids in general learning. REM sleep is important for your mind-creative thinking, learning, and memory all benefit from it.Įssentially, deep sleep is very important for your body and mind.

Atonia, temporary paralysis of your muscles, affects all your muscles with the exception of your eyes and the muscles that control breathing. Your mind is its most active-almost as active as when you are awake-yet your body is paralyzed. REM sleep, or Rapid Eye Movement, is the 4th and final phase. This phase of sleep is believed to be imperative for bodily recovery, growth, and the immune system. Tissue growth and repair happen in this phase and cellular energy is restored. It is much harder to wake up at this point and your brain starts to become much more active. Phase 3Īlso known as the healing phase or slow-wave sleep, this is deep sleep. Your breathing and heart rate begin to slow and your temperature starts to drop slightly as your muscles relax. In this phase, you begin properly sleeping. As the mind slows, there can be slight twitches in the body. This is a very light sleep that is easy to wake up from. There are four phases of the sleep cycle: Phase 1 Specifically, how much deep sleep do you need?īefore we dive into how much we need, let’s first clarify what exactly deep sleep is.

We all know we should be getting somewhere between 7-9 hours of sleep every night, but most people still aren’t sure how much of each individual stage of sleep you should get.
