Understanding Deep Sleep
When you sleep, you go through two stages: non-rapid eye movement (NREM) and rapid eye movement (REM). In NREM, the body goes through four stages. Deep sleep occurs in stages three and four. Your brain waves, heartbeat, and breathing rate become the slowest. Moreover, the muscles relax, and it becomes difficult to be woken up even with the loudest noise. The body disengages itself entirely from the environment.
It allows the body to refresh and repair itself, particularly the brain. This boosts physical and mental health. What’s more, one study indicates that deep sleep is vital for restoring your brain’s capability to learn.
Why Does Deep Sleep Matter?
Getting deep sleep is incredibly important, just like eating a nutritious meal or exercising. It would help if you get more deep sleep because of the following health benefits:
- It promotes memory consolidation and learning – Deep sleep is also known as “sleep-dependent memory processing.” It may improve short-term and long-term memory combination and learning.

What Amount Of Deep Sleep Is Required?
The amount of deep sleep one needs depends on age, and the total amount of sleep one has each night. Generally, seven to nine hours of sleep is enough to experience deep sleep’s rejuvenating and relaxing benefits. NREM accounts for about 75% of your sleep, whereas REM accounts for 25%.
Out of this, 13-23% is spent in deep sleep. For instance, if you sleep for seven hours every night, you spend 55-97 minutes in a deep sleep. Besides, deep sleep decreases as one ages. If you are 30 years and below, you may enjoy 2 hours of deep sleep every night. However, if you are over 65 years, you might get 30 minutes or none at all.
To some extent, the body self-controls the amount of deep sleep. For example, if you are sleep deprived or you don’t experience quality sleep, you might take more time in deep sleep.
