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

Sweating is a physiological function of human body to excrete and regulate body temperature, but if the way of sweating, the amount, color and smell of sweat change, it can be regarded as a precursor of some diseases and should be paid attention to. The following is an explanation of some common sweating phenomena from the perspective of traditional Chinese medicine:

First, spontaneous sweating

It is not because of the sultry weather, taking sweating drugs and other stimulating factors that you often sweat. This situation is called "spontaneous sweating". Spontaneous sweating is mostly caused by weak lung qi deficiency, weak defensive yang qi and leakage of body fluid, so it is often accompanied by symptoms of yang deficiency such as fatigue, burnout, shortness of breath and chills. It is more common in children with rickets and hyperthyroidism.

Second, night sweats

Sweat when you sleep, and sweat when you wake up. Night sweats are often caused by hyperactivity of yang due to yin deficiency, yin not controlling yang, and sweating in body fluids, so they are often accompanied by symptoms such as five upset, insomnia, dry mouth and throat. Common in patients with pulmonary tuberculosis infiltration.

Third, the sweat of war.

That is, sweating after chills is a manifestation of the struggle between good and evil in the process of epidemic febrile disease. After sweating, the fever is gone, the pulse is still, and the body is cold. This is a good phenomenon, indicating that the evil has gone and the vitality has recovered. If the limbs are cold and irritable after sweating, it means that vital qi is invincible, and vital qi goes down with weakness, which is a critical illness. War sweat is more common in the early and middle stages of various infectious diseases.

Fourth, don't sweat

It means that when the condition is critical, the vital qi is weak, the yang is about to take off, sweating profusely, accompanied by shortness of breath, cold limbs, weak pulse, and sometimes not critical, which is a sign that the yang will be exhausted, and it is more common in patients with heart failure and collapse.

Five, head sweating

Sweating is confined to the head. Most of them are caused by pathogenic heat in the upper jiao or damp-heat stagnation and steaming in the middle jiao, which is more common in Yangming heat and damp-heat syndrome. If you see it after a serious illness, or if the old man is panting and sweating, it is mostly empty. For example, a sudden profusion of forehead sweat at the end of a serious illness is a crisis in which yin deficiency goes up, yin deficiency cannot attach yang, and yin and body fluid take off with qi. However, children often sweat on their heads while sleeping. If there are no other symptoms, it is not a symptom.

Sixth, sweating

Commonly known as "half-body sweat". It is located on the left or right, upper body or lower body. They are all caused by wind phlegm or rheumatism blocking collaterals, or poor camp defense, or disharmony between qi and blood. More common in patients with rheumatism or hemiplegia. If the elderly sweat, it may be a precursor to a stroke.

Seven, cold sweat

Refers to sweating due to cold limbs. No fever before sweating, no thirst. Often accompanied by listlessness, pale face, loose stool, long urine, slow pulse, pale tongue and other cold symptoms. It is mostly caused by yang deficiency and insufficient defensive qi, and it can also be caused by fright.

In addition, sweating in the palms is often caused by mental stress, and sweating in the chest is caused by overthinking. People who often sweat with a little movement are either too fat or too weak. The sweat of diabetics is slightly fragrant, and the sweat of patients with liver cirrhosis has a special liver taste.

Extended data

The relationship between sweat and health

98 ~ 99% of a drop of sweat is mainly water. The specific gravity of tourmaline steaming room is about 1.002 ~ 1.003, and the pH value is 4.2 ~ 7.5. NaCl is about 300mg/ 100ml.

1 ~ 2% is a small amount of urea, lactic acid and fatty acid.

Sweat is the liquid secreted by sweat glands. Sweating due to thermal stimulation caused by the increase of external temperature or internal heat production is called perceptual sweating. At this time, the sweating area is widely distributed, and the skin in all parts of the body, especially the forehead, neck, trunk, waist, back of hand and forearm, is the most; Followed by the neck, trunk side and most limbs; Once again, the inner thigh and armpit; At least the palms and feet. Mental stress can also lead to sweating, and sweating centers are distributed in all parts of the central nervous system. Normal people unconsciously evaporate about 600 ~ 700 ml of water within 24 hours.

Sweating is divided into active and passive. Passive sweating refers to sweating due to sultry weather and irritability, which is harmful to human body. On the contrary, the sweat that the human body actively exercises is called active sweating, which is conducive to maintaining the temperature in the human body and emitting heat, which is beneficial to people's physical and mental health.

The function of sweat is to regulate body temperature. Think about it carefully, the human body is really like a precise machine. If you don't sweat, that's not good. Exercise, blood circulation is accelerated, body temperature rises and sweats, so that body temperature drops; When it is cold, sweat glands and pores contract, thus stopping sweating and preventing body temperature loss.

Sweat is the "air conditioner" of our body. Chinese medicine believes that sweating is a kind of detoxification in summer. There are two ways for people to detoxify: one is urination, and the other is sweating. Sweating is the most effective way to detoxify. Only in summer can you sweat naturally all year round, which will be good for human metabolism, meridian balance and immune system health. If you don't sweat for a long time, your skin won't breathe, which will eventually cause many disorders in your metabolic system, and the detoxification function of this skin will be transferred to your kidneys and liver.
