Getting a good night's sleep depends on how much deep sleep you get

People often use the phrase "sound sleep" to describe the quality of sleep. In fact, these adjectives mean "deep sleep." It's used throughout the night to get the most important part done and to feel like you've slept well when you wake up, so it's called "golden sleep."

A person's night sleep is typically divided into five to six cycles, each lasting about 60 to 90 minutes. The sleep cycle consists of a non-REM cycle and a REM cycle. The non-REM cycle is divided into four stages: light sleep, light sleep, middle sleep and deep sleep.

Deep sleep can play a big role in relieving fatigue.

Among them, the light sleep period and the light sleep period accounted for 55% of the total sleep time, but did not help to relieve fatigue. After deducting REM cycles, the remaining "deep sleep", which combines intermediate and deep sleep periods, has a significant effect on fatigue relief. However, deep sleep only accounts for 25 percent of total sleep time. Anything much less than that and you'll have trouble sleeping.

In deep sleep, the cerebral cortex is inactive and completely rested, and there is no possibility of dreaming as in light sleep cycles, which has a key effect on fatigue, energy recovery and immune resistance.

And during deep sleep, growth hormone is released in large quantities, helping to repair damaged cells and promote growth. Research has also shown that deep sleep plays an important role in consolidating memories. People who don't get enough deep sleep tend to have memory problems.

The "deep sleep" stage plays a decisive role in the overall quality of sleep. Some experts describe deep sleep as a child's growth and intellectual development. Young people are energetic; Middle-aged people are physically strong; It is important to ensure the health and longevity of the elderly. Therefore, increasing the amount of deep sleep is to fundamentally improve the quality of sleep and maintain a good physical and mental state.

Deep sleep is only 15-25 percent of total sleep.

Different people need different amounts of deep sleep. The average adult typically gets only 15 to 25 percent of a night's deep sleep. Based on eight hours of sleep, deep sleep is about 72 to 120 minutes, or one to two hours.

No, the longer you sleep, the deeper you sleep.

It's important to note that you shouldn't try to increase the amount of deep sleep you get by sleeping longer, because even if you sleep longer than usual, there's a limit to how much you can add. If you can fully grasp the stages of deep sleep, you'll feel refreshed the next day, even after four or five hours of sleep. However, if you spend the whole night in initial or light sleep, even after 8 or 9 hours of sleep, you will wake up the next day feeling lethargic and as if you didn't wake up.

In fact, deep sleep cannot be seen, touched, or touched, and can only be judged by EEG. But if you think you're constantly suffering from a lack of "deep sleep," professional doctors suggest these three ways to increase your deep sleep:

  • Moderate exercise: Studies have shown that moderate exercise during the day can increase the amount of deep sleep you get at night.
  • Control your weight: Obese people are more likely to have sleep disorders than the average person. For example, heavy snoring may trigger sleep apnea, which reduces the amount of deep sleep.
  • Rational drug use: The use of sleep AIDS under the guidance of doctors can increase or maintain a certain amount of deep sleep time.
