Introduction: Sweating is a way for the human body to expel toxins and regulate body temperature, and the amount of sweat will vary according to the individual's constitution.

When people are in a hot climate, or dress too hot, or eat food that is too hot, or exercise vigorously, their bodies sweat. This is normal, sweating means that the body regulates body temperature through sweating and excretes metabolites from the body, proper sweating is beneficial to health.

But in life, some people always sweat? Some people rarely sweat, what is the reason?

TCM believes that there are six types of abnormal sweating

Since people are not affected by external environmental factors, they usually sweat during the day, but sweat more during exercise, which is called "spontaneous sweating", which is common in yang deficiency and qi deficiency, and yang qi is not enough to protect them.

Sweating a lot during sleep and not sweating when waking up, known as night sweats, is common in yin deficiency, and is accompanied by fever, thirst, irritability, poor sleep quality and other diseases.

That is, sweating after the whole body trembling, sweating after war sweating is a manifestation of the struggle between good and evil in the process of temperature disease, if the fever subsides after sweating, the pulse is calm, and the body is cold, it means that it is already safe and vitality has been restored, which is a good phenomenon, if the fever subsides after shivering and sweating, this is the victory of healthy energy in sweating.

If the limbs become cold and restless after sweating, it means that good is too strong for evil, and if true qi is weakened, this is a serious symptom, and war sweat is common in the early and middle stages of various infectious diseases.

If sweating, especially cold sweats, is accompanied by a range of symptoms, such as chest tightness or chest pain, it can be a precursor to a heart attack.

Because when there is a problem with the heart, blood stasis in the systemic circulation can cause obstruction of peripheral blood flow, resulting in increased capillary pressure and fluid leakage.

Some people sweat very little in life, even in the hot summer, they are not easy to sweat, this situation is also abnormal, this may be related to physical weakness, in the process of physical decline, abnormal perspiration may occur, at this time, many people will sweat less.

Dehydration is characterized by heavy sweating, sweating like beads, often accompanied by low air pressure, mental fatigue, cold extremities, weak pulse or dispersion, it usually occurs when the disease is critical, which is a sign of critical illness, dehydration is also called absolute sweating.

Why do some people sweat more and some people sweat less?

Sweat is excreted through sweat glands, the number of sweat glands varies from person to person, evenly distributed between 2 million and 4 million, the more sweat glands, the more people sweat, people think that male androgens are strong, the number of sweat glands is much more than female, in fact, women have more sweat glands than men, concentrated in the armpits and navel.

People who exercise regularly and are physically strong have strong muscle activity, and they can easily cope with the same amount of exercise as ordinary people, so there will not be too much sweat coming out, the body is weak, the humidity is too great, and more calories need to be consumed to complete this exercise process, and they will sweat a lot.

Many people have endocrine disorders, male hormones are too strong, the body is full of yin and yang, so they will sweat excessively, some elderly people suffer from cardiovascular and cerebrovascular diseases, lack of normal oxygen supply, resulting in chest pain, angina, panting, sweating.

It is said that some diseases with excessive hormones affect the sympathetic nerve, and the secretion of hormones naturally stimulates the secretion of sweat glands.

Does less sweating mean good health?

At first glance, sweating may not seem like a good sign most of the time, so, does less sweating mean health? Traditional Chinese medicine believes that people who sweat less may just because the yang is slow, the qi is out of reach, and the sweating is less at the same time, if it is accompanied by symptoms such as palpitations, irritability, and sore tongue, it means that the body is very hot and needs timely intervention to speed up the operation of yang in the body and promote perspiration.

Ordinary normal sweating can be relieved by itself, but pathological sweating requires professional treatment, usually nocturnal sweating and spontaneous sweating should be distinguished, we can detect whether sweating is abnormal by recording, find out the cause of sweating, and carry out targeted treatment.

TCM can judge the physical condition based on the physiological manifestations of sweating time

Some people sweat a lot during the day, whether in spring, summer, autumn or winter, even if they are only slightly active or inactive during the day, this kind of person has a bad appetite, affected by the season, he always catches a cold and speaks softly, which is also a manifestation of the deficiency of qi in Chinese medicine.

In addition, some people do not sweat during the day, often sweat at night, sweat profusely when sleeping, and stop exercising after waking up, such people are usually accompanied by fever in the hands and feet, red face and ears, dry mouth, which is a manifestation of physical weakness.

Normal sweating is a physiological feature, hot weather or after strenuous exercise, the body will sweat frequently, the patient needs to regulate the body temperature, this is a very normal phenomenon, for example, after half an hour of exercise will slowly sweat, some people will be nervous and sweating because of the high temperature.

If the sweating process is accompanied by the same headache, pallor, and poor appetite, it may be related to weakness and other diseases, and it is necessary to go to the hospital for examination to see if there is a gastrointestinal disorder with abnormal thyroid function.

Sweating on the head and forehead, but not on the body, is likely to cause moist heat, such as overheating on the upper burn; Sweating in the heart is a belief that is more energetic and causes bodily fluids to flow out of the chest. If sweating is frequent and does not relieve, it may be sick, which is mainly seen in patients with heart and spleen deficiency, such as sweaty hands and feet, or physical deficiency.

Some people sweat the upper body, sweat the upper body, and sweat the lower body, this type of person is mainly seen in diabetics, it is caused by poor circulation and blockage of body fluids.
