During the Warring States Period, Wen Zhi, a famous doctor, said to Qi Weiwang, "My way of keeping in good health is to put sleep first. People and animals can only grow up by sleeping, which helps the spleen and stomach digest food. So sleep is the first supplement to health. If people don't sleep for a night, they can't recover for a hundred days. " Li Yu, a physician in the Qing Dynasty, also pointed out: "The key to keeping in good health is to put sleep first. Sleep can be refined, sleep can nourish qi, sleep can strengthen the spleen and stomach, and sleep can strengthen bones and muscles. " Therefore, people should conform to the laws of nature and follow the sun, that is, I wake up in the morning and sleep in the morning, and form the habit of going to bed early and getting up early.
But for modern people, staying up late has become the norm of life! According to the survey data of Amazon China, 8 1% people in China sleep less than 8 hours. Nearly 60% people usually fall asleep at midnight 1 1 to morning 1, while 46.6438+0% people get up before 7 o'clock. The reason why it is difficult for most people to form the habit of going to bed early and getting up early is that there are many misunderstandings about sleep besides some people's own bad sleep habits:
1. Some people think that it is enough to sleep for seven or eight hours every day. It doesn't matter if you stay up late at night, just make up your sleep during the day.
2. Many people stay up late or sleep badly, only knowing that they will feel mentally exhausted the next day, but they don't know how much harm it will do to their bodies.
Many people think that insomnia and difficulty in falling asleep are just minor problems. Just take a few sleeping pills, and they won't think it's caused by internal disorder.
Some people like reading and writing articles in the evening. After 23 o'clock, they feel very quiet, energetic and efficient.
In order to get out of the above misunderstanding about sleep, we must first know the harm of bad sleep habits to the human body and when sleep is good for health.
