Sleep is not just a break from a long day, but rather a basic vital process that restores the body's activity and balances its functions. Among the different stages of sleep, deep sleep is the most important, as it is during it that processes occur that enhance physical and mental health.
Deep sleep is not just a luxury, but rather a basic need that affects the quality of life. In this article, we will talk about the concept of deep sleep, its importance, the stages associated with it, and its impact on general health, in addition to tips to improve its quality.
First: The concept of deep sleep
Deep sleep is a stage of sleep also known as slow-wave sleep (SWS).
- It is characterized by decreased brain activity and breathing rate.
- The body is in a state of complete relaxation, with a decrease in heart rate and blood pressure.
- This stage often occurs in the first half of the night, and constitutes about 13-23% of the total sleep cycle.
Deep sleep is the time when the body focuses on renewal and repair, and it is different from light sleep or dream sleep (REM).
Second: Sleep stages and how deep sleep occurs
Sleep consists of several cycles, and each cycle contains 4 stages:
1- The first stage (very light sleep):
The beginning of falling asleep, and eye movement is slow.
2- The second stage (light sleep):
Sleep becomes deeper, with a slight decrease in body temperature and heart rate.
3- The third stage (deep sleep):
Slow brain waves begin to appear, and the person is unresponsive to external stimuli.
4- The fourth stage (REM - dreaming sleep):
During which dreams occur, and the brain is active while the body is partially paralyzed.
Deep sleep appears in the third stage, as the body reaches a state of complete recovery.
Third: The importance of deep sleep for human health
