The way of health preservation is ancient. The classic of traditional Chinese medicine "The Yellow Emperor's Classic of Internal Medicine" has a detailed introduction to health preservation. After the people's living standards have gradually improved, people have begun to pay attention to health preservation. The ancients have summed up a lot of health care experience. The saying "don't spit in the morning, don't leak semen in the afternoon, and don't sweat in the evening" is also a valuable knowledge left to us.

"Don't spit in the morning, don't leak semen in the afternoon, don't sweat in the evening" literally means, don't spit after getting up in the morning, don't discharge semen at noon, don't sweat at night, these are related to the specific meaning of physical health what is it then? let's figure it out together!

1. "Do not spit in the morning"

When you wake up in the morning when the kidney qi and yang qi are relatively abundant, the saliva contains the kidney qi, swallowing the saliva will help nourish the kidney, replenish the kidney qi, and promote the rise of yang qi in the body.

If you spit out saliva in the morning, it will damage the kidney qi in the body and lead to the loss of yang qi. It can be seen that saliva is of great significance to human health.

From the perspective of modern science, water accounts for about 70% of the human body, which is very important for the human body. When the body lacks water, the normal operation of various organs will be blocked.

The salivary enzymes and other components in saliva can promote digestion and help the body to enhance the anti-virus effect of antigen cells. Try not to spit after getting up in the morning.

Drinking a glass of warm water after getting up in the morning helps to supplement amino acids, vitamins, dietary fiber and provide energy for the life activities of the day.

Second, "no leaking essence"

The body is in a state of exhaustion after a morning of exertion, and needs to replenish nutrients and take a proper nap to restore physical strength for the human body.

At noon, it is not recommended that you take exercise to consume energy in your body, otherwise it will reduce your own oxygen and blood pressure levels and make your body in a state of exhaustion.

After lunch, the blood in the body will run faster and enter the digestive system to help gastrointestinal motility, digestion, and absorption of food. Excessive consumption will cause damage to the body.

After overdrafting, the symptoms of kidney deficiency will increase, and the whole person looks listless. Although it sounds absurd that I do not thank Jinshui, it does have a certain scientific basis.

3. "No sweat at night"

Working at sunrise and resting at sunset is the law of nature. The human body must follow this law in order to obtain health. Night is the time when the body enters a state of rest to replenish energy.

The body repairs itself during sleep at night. Only in the state of deep sleep can the brain neurons and neurotransmitters obtain nutrients and maintain the normal operation of various organs.

If you sweat profusely when you sleep at night, it may indicate that there are pathological changes in the body. Excessive sweating will lead to fatigue and aggravate damage to the kidneys.

At night, the time for detoxification of various organs is short, and the body's metabolic rate will be in a slow state. If you sweat a lot, it means that the body has symptoms of kidney deficiency or physical weakness.

Therefore, it is not recommended for everyone to exercise vigorously at night. You should follow the laws of nature and achieve a state of working at sunrise and resting at sunset to ensure a good quality of sleep.

The common sayings handed down by the ancients are also the essence of their combination of life and semen, and they are more worthy of our attention, study and follow.
