Sleep can provide our body with sufficient physical strength and energy to maintain daily activities; it can be said that sleep is an important guarantee for the continuation of life. There is even an old saying: Medicinal supplements are worse than food supplements, and food supplements are worse than sleep supplements.
Dr. Wang has also emphasized many times that sleeping is the best health preservation, but now with the continuous development of the Internet and mobile phones, it is too difficult to have a good sleep. After all, there are too many reasons why everyone is unwilling to sleep: watch Yiji TV series and sleep, play a game and sleep, and browse the circle of friends again before sleeping...
However, no matter what the reason, you must sleep at the following three points, otherwise the consequences will be really serious!

1. After staying up late,
Staying up late for a long time and lack of sleep will not only make people feel deeply tired and have a low mood, but will also induce heart disease, sudden death, and cancer! Therefore, you must make up for your sleep after staying up late. Although making up for your sleep cannot completely eliminate the adverse effects of staying up late, it is still very necessary and important: Studies have shown that a half-hour lunch break at noon can make up for the missing hour of sleep at night and improve the body's alertness, mobility and mood; and in the view of traditional Chinese medicine, 11:00 to 13:00 is the most prosperous time of the day. At this time, a nap can compensate for the lack of sleep at night and protect the body's yang energy. Therefore, no matter what reason you stay up late, it is best to take a rest at noon.

2. In the early stage of a cold
When the cold has just developed, if handled properly, the virus can be eliminated in the bud and prevented the disease from continuing to develop. Some people just have a good sleep in the early stage of a cold, which is the reason.
In addition, if you have a cold, it is recommended to rest at home and avoid going to public places. This is not only responsible for the public, but also for your health. Because the human immune system is fighting the virus at this time. If you do not rest well, you will increase your exercise volume, which is equivalent to increasing the burden on your body and helping the virus.

3. Feeling fatigue
Fatigue is a signal sent by the body, reminding your body that it has exceeded the normal load. However, many people are obviously very tired, but they still refuse to rest well. They also have to stay up late to play with their mobile phones and go out shopping for dinner. They do not know that when the human body is overworked, it is difficult for the immune system to continue working, which will lead to neurological disorders and endocrine disorders, causing immune dysfunction and induce various diseases. Moreover, excessive fatigue can easily lead to electrophysiological disorders of the cardiac artery, or continuous spasm of the coronary artery, stenosis of blood vessels, insufficient blood supply, and eventually sudden death; therefore, when you feel tired, you must have a good sleep.
