What are the disadvantages of sleeping too much?

As for rest, this is something each of us must do. Only by ensuring sufficient rest can people have a good physique and have the energy to do many meaningful things during the day. The amount of rest represents the quality of a person's life. Many long-lived people get enough rest, so the way they live is important and many people can learn from them. Let’s now talk about the pros and cons of sleeping too much.

1. According to medicine and my experience and observation, a person can only sleep for a maximum of two hours. The rest is a waste of time lying on the pillow and dreaming. There is no one who does not dream. As for waking up and feeling that he did not dream, it was because he forgot. Usually two hours of sleep is enough for a person, so why do some people need to sleep seven or eight hours? That is because you have developed the habit of staying in bed and lying on the pillow to rest. It is not that we need that much sleep time. Especially those who meditate and practice kung fu know that if you close your eyes and really fall asleep for three minutes at noon, it is equivalent to sleeping for two hours, but you have to sleep at noon. At night, you should fall asleep at midnight, and five minutes is equal to six hours.

2. The knowledge about time is very profound, and it is related to the laws of the universe, the laws of the earth, and the principles of yin and yang in the Book of Changes. You will feel that a force is coming down from under your heart and merging with the force in Dantian (above the kidneys), the so-called "water and fire are in harmony". You will feel refreshed and you will have enough sleep and be full of energy. Therefore, people who suffer from insomnia or really need to stay up late at night must sleep at midnight, even for twenty minutes. Even if they can't sleep, they must train themselves to fall asleep. After midnight, around 12:30, you won't want to sleep, which is bad. What’s worse is that when it’s almost dawn, at four or five o’clock, or at five or six o’clock in the morning, you feel sleepy again. If you fall asleep at this time, you will feel dizzy all day. So for those who want to work late at night, at midnight, even if there is a big thing, you have to put it down and sleep for half an hour. When it is the morning hour, you must not sleep even if you want to. That way you will be energetic enough for the day. However, people with insomnia stay up past midnight, tossing and turning in bed, and finally fall asleep near dawn, feeling groggy until the next afternoon. That is why you feel like you have insomnia and are lacking sleep, but in fact it is because you lack experience.

3. Wen Zhi, a famous doctor in the Warring States Period, said to King Wei of Qi: "My way of keeping in good health puts sleep first. Humans and animals can only grow through sleep. Sleep helps the spleen and stomach digest food. Therefore, sleep is the first supplement for keeping in good health. If a person does not sleep for one night, the loss will be difficult to recover in a hundred days." 21:00 pm to 5:00 am is the effective sleeping time. Humans are animals and belong to the same biological category as plants. During the day (5 a.m. to 9 p.m.), activities generate energy. At night (9 p.m. to 5 a.m.), cell division begins, converting energy into new cells. This is the time for human cells to rest and recuperate, and to innovate. It is also the time when humans turn to the side of the earth that is facing away from the sun. Yin is the master of tranquility and is the best time for people to sleep. Only by resting at this time can they have a good physical and mental state. This is the same reason why babies who sleep a lot grow fat and fast, while children who are fussy about sleep are underdeveloped. Sleeping is a major function of health preservation. Preservation means using a large number of healthy cells to replace corrupt cells. If you can't sleep all night, new cells cannot be replaced. If one million cells die during the day and only 500,000 cells are replenished at night, your body will be in deficit. Over time, you will become skinny, like a skinny radish. Why are there centenarians in the world? Because they go to bed on time at 9 p.m. every night.
