1, enough sleep time
Our sleep is divided into light sleep and deep sleep. During the rapid eye movement period, we slowly enter deep sleep from light sleep. The most efficient part of our sleep is between 10:00 pm and 2:00 am. Therefore, to have a thorough rest, you must fall asleep before the cycle begins. In addition, research shows that going to bed early and sleeping for a long time can help us relax and have a more positive attitude.
2, the body's self-regulation time
When we are in deep sleep, our body will produce repair hormones to repair ourselves. This vital activity will ensure that we are in the best condition tomorrow, especially for athletes.
3. Relieve psychological stress
Lack of sleep will make the cortisol level in the body too high, and the sense of stress will double. Too much cortisol can make us feel anxious and affect our health. However, long-term deep sleep can effectively control cortisol levels.
4. Reduce the risk of illness
Studies show that people who go to bed early are healthier than those who work at night or just stay awake. People who lack sleep are more likely to suffer from diseases such as heart disease and hypertension.
The researchers also found that 10:00 pm to 2: 00 am is very important for the production of our immune cells. People who don't sleep well have a lower response to virus antibodies, which means they are more likely to get sick.
