In fact, the human body can regulate its body temperature by sweating. For example, in a particularly hot environment, the human body may dissipate heat by sweating a lot to achieve the effect of cooling the body. In addition, sweating can also excrete metabolites, resist bacteria and moisturize. Therefore, sweating is a physiological phenomenon beneficial to the body under these circumstances.
However, in some pathological conditions, the human body will also sweat abnormally, or some abnormal sweating will also prompt some diseases. For example, diseases such as tuberculosis can cause patients to have afternoon hot flashes and night sweats. Hyperthyroidism patients will also sweat a lot, but hyperthyroidism patients will also have other accompanying symptoms such as exophthalmos and increased heart rate. More than 60% of diabetic patients will have perspiration disorder. It can also be said that abnormal sweating is often an important signal of diabetic autonomic neuropathy, such as hemiplegia.
In short, normal sweating is a physiological phenomenon, and in some cases, abnormal sweating is indeed a hint of some diseases. If it does appear, we must pay attention to professional hospitals for inspection.
There are many reasons why people sweat, and it is far-fetched to explain sweating with a single constitution.
In most cases, sweating is a normal physiological phenomenon. It is true that some people sweat more easily, but there are many reasons to regulate human sweating, some of which are not the human body's own reasons at all.
For example, it is easy to sweat after eating Chili, because capsaicin can open an ion channel in the human body, which makes people feel that they will naturally sweat in very hot summer.
Sweating after eating pepper can be said to be pepper constitution, which is a common phenomenon. What I want to say today is that this is a common phenomenon. What I want to say today is an unusual sweating: hyperhidrosis.
You may have heard of the legendary bloody BMW. It is said that after running, the sweat is as bright as blood. Unfortunately, this kind of blood horse is only recorded in ancient books, and now it can't be found.
But people with hyperhidrosis can still see it from time to time, although it is rare.
There is a case (1), a 22-year-old Indian male, who can dye his vest blood-red elegance as soon as he sweats. Of course, this bloody man was not born like this, but only started in the last six months. After a series of inspections, the hospital found no problems. After the doctor carefully asked the sweaty man about his eating habits, he suddenly realized.
It turns out that sweaty men drink cranberry juice for a long time. Recently, a slim female singer said that she drinks 8 cups of milk tea every day. As a result, someone uploaded a video and found that the female singer took two drinks and threw the milk tea into the trash can. However, if a sweaty man drinks eight cups of cranberry juice, he really drinks every drop. As a result, he felt that the whole person had turned into walking cranberry juice, which leaked when he sweated.
How to prove that the sweat secreted is cranberry juice instead of blood? The researchers analyzed the sweat of sweaty men with a spectrophotometer and found that the absorption peak was consistent with that of cranberry juice.
Therefore, if you want to ask what constitution a bloody man is, you can only say that he is clinging to Mei's constitution.
Of course, there are other sweat colors similar to hyperhidrosis, such as blue (2) or blue-green (3).
The blue-green case also comes from India. The patient is a middle-aged man who has been eating some kind of "elixir" for a long time. It is found that there are more copper ions in elixir and the concentration of copper ions in sweat is also high.
After stopping using "elixir", the blue-green sweat disappeared.
So if you want to ask the Indian middle-aged man what his constitution is, you can only say that he ate elixir and became a copper ion constitution.

In hot summer, you will sweat if you are not careful. Sometimes just a little exercise or a meal will make you sweat. Sweating is a normal physiological phenomenon. The human body is a warm-blooded animal, and sweating can keep the body temperature stable.
But sometimes it is found that some people live in love sweating and some people don't live in love sweating. Why? There are several main reasons:
1. Sweat itself has individual differences: sweat is secreted by sweat glands, and the number of sweat glands varies from person to person, which is also related to gender.
2. Sweating is related to the amount of body fluids in the body: people who love drinking water sweat more, while people who don't live in love sweating drink less. If you don't like drinking water at ordinary times, it is easy to dehydrate after a lot of exercise. We can judge whether the body is short of water by observing the color of urine. Generally, urine is light yellow, which proves that the body is not short of water.
3. It is related to the intensity of exercise: during exercise, muscles contract, blood circulation accelerates and body temperature rises. In order to keep body temperature and dissipate heat, the body will sweat. The more intense the activity, the greater the intensity of exercise and the greater the amount of sweating.
Through sweating, the body can regulate body temperature, dissipate heat, and sweat also has the functions of excreting metabolites, resisting bacteria and moisturizing. The most important factor affecting the amount of sweating is the environment. The higher the temperature, the more you sweat, and people with fat or high sebum content are more likely to sweat. Physiological sweating is a normal physiological phenomenon, so there is no need to worry about it, but some sweating may be caused by some diseases and need our attention.
1. Metabolic patients such as diabetes love sweating: If the blood sugar of diabetes is not well controlled, symptoms of hyperhidrosis and polyuria will occur; Hyperthyroidism patients will also suffer from love sweating due to abnormal thermal metabolism.
2. Hyperhidrosis: Hyperhidrosis patients will involuntarily sweat a lot even in the cool season. Hyperhidrosis has little to do with environmental factors, but is mostly influenced by emotions.
Abnormal sweating needs to be examined and treated in a professional hospital.
Sweating is the process that sweat glands excrete sweat through skin pores. It is a way to adjust one's own temperature, which is popularly called heat dissipation.
Sweating when the weather is hot and the amount of exercise is large, and sweating caused by eating some irritating foods, such as pepper, garlic, ginger, cocoa and coffee, is mostly a physiological phenomenon.
If the weather in love sweating is to lower the skin temperature, then the inexplicable sweating in winter is probably caused by physical weakness. Sweating caused by pathological reasons is the most common:
1. External manifestations of diseases, such as hyperthyroidism, autonomic nervous dysfunction, rheumatic fever, tuberculosis, etc. Patients often have abnormal phenomena such as spontaneous sweating and night sweats. After these systemic diseases are controlled, hyperhidrosis can be solved.
2. Mental sweating caused by mental stress and emotional excitement is caused by the increase of sympathetic nerve excitability. Dr. Xu met such a patient. In winter, the palms and soles of his hands were sweaty, and even sweat dripped down his hands. It is necessary to use some anti-sympathetic drugs, or sympathectomy and other treatment methods.
The above are some situations related to sweating that Dr. Xu thought of, hoping to help everyone!
People often sweat easily after exercise or when the weather is hot, which is the need of human body to expel heat. Sweat evaporation takes away body heat and maintains normal body temperature. Generally speaking, fat people sweat more easily than thin people, but it is not normal to sweat a lot when the weather is not hot and there is no exercise or to sweat a lot after falling asleep.
What is the constitution of people who sweat easily? Traditional Chinese medicine often says that people who sweat easily have weak constitution, while western medicine has no constitution. Abnormal hyperhidrosis may indicate some kind of disease. First of all, patients with hyperthyroidism have strong metabolism, are more prone to sweating than ordinary people, and may also have symptoms such as large neck, prominent eyes and large appetite. Diabetes or hypoglycemia patients are more likely to sweat, and hypoglycemia patients are often accompanied by symptoms of palpitation, dizziness and cold sweat.
After falling asleep, we call it night sweats. Except for some children who have physiological night sweats, adult night sweats are generally abnormal. For example, tuberculosis patients will have night sweats, and there will be symptoms of low fever and emaciation in the afternoon. Therefore, for people with long-term night sweats, it is recommended to go to the hospital to further clarify the cause.
Sweating easily has nothing to do with physical fitness, and it may be sweating.
Under normal circumstances, sweating is not a bad thing, but the human body is adjusting its temperature. When the body temperature rises, the nervous system sends a sweat signal to the sweat glands, so it sweats.
There is a loophole in this function, because the nervous system is responsible for sending signals. When a person is in a state of tension, the nervous system may send out wrong signals, which may lead to sweating, and it is often the palms that sweat. Although this situation does not belong to regulating body temperature, it is normal.
An adult may sweat 2-4 liters per hour, with a maximum of 10- 14 liters every 24 hours. If the temperature is not high, you don't exercise, you don't feel nervous, anxious or stressed, but you still sweat a lot, which may belong to hyperhidrosis, and its incidence rate accounts for 2-3% of the total population.
Hyperhidrosis patients still sweat instead of sweating to lower their body temperature, such as staying in air-conditioned rooms, sitting and watching TV, and even sweating in swimming pools. Sweating usually occurs on hands, feet, armpits and face, at least once a week, usually when awake, sweating often on both sides of the body.
There are two kinds of hyperhidrosis, primary hyperhidrosis and secondary hyperhidrosis. The cause of primary hyperhidrosis is unknown, and many people have hyperhidrosis since childhood, which is probably a genetic factor. Secondary hyperhidrosis can find out the causes, such as taking certain drugs, diabetes, hot flashes in menopause, hypoglycemia, hyperthyroidism, certain tumors, heart disease, nervous system abnormalities, infectious diseases and so on.
If it is really hyperhidrosis, take a bath every day and keep your skin dry, especially between your toes and under your arms. Wear shoes, socks and clothes with natural texture. Don't wear the same pair of shoes for two consecutive days. Change socks frequently, use sweat-absorbent powder, and take every opportunity to go barefoot. Solve the cause of secondary hyperhidrosis and treat severe primary hyperhidrosis with antiperspirant.
As for all kinds of physique, it belongs to pseudoscience, so don't pay attention and don't believe it.
Chinese medicine and western medicine have completely different theories about sweating. Here I mainly talk about it from the perspective of western medicine.
Our bodies generate heat, just as machines work to generate heat. Our bodies and machines also need to discharge the excess heat generated to ensure that the temperature of our bodies and machines is not too high. If the machine is very hot, it will burn out. Similarly, when the body heat is too high, it will also lead to convulsions, coma, liver and kidney failure, and even death.
What does our body rely on to dissipate heat? One of the most important ways is sweating. Sweat can take away the heat in our body. Everyone should have this impression in life. When we have a fever, if we break out in a big sweat, then our body temperature will drop-the fever will drop. If you have a fever, you don't sweat all the time, and your body temperature can't drop. It's very uncomfortable and dangerous, especially for children. Because the nervous system is not fully developed, it is easy to twitch because of high fever.
When the weather is hot, our body will increase the amount of perspiration, thus ensuring the normal temperature in the body. When a person lives in a place that is not too hot, such as Yunnan people (it is spring all year round, and it is a little hot this year), and suddenly goes to a very hot place, such as Hainan, he will feel very hot at first, sweat less, feel uncomfortable, and suffer from heatstroke. But after about two weeks, our bodies adapted, the amount of sweating increased, and we adapted. Therefore, sweating is very important to our human body.
However, in some diseases, the amount of sweating will increase. Let me give you a list.
(1) Tuberculosis
A typical manifestation of tuberculosis patients is night sweats, that is, sweating at night or during lunch break. The patient also has symptoms of long-term cough, expectoration and hemoptysis.
(2) hyperthyroidism
Hyperthyroidism patients have increased basal metabolic rate due to the increase of thyroid hormone secretion in the body. The patient is very, very afraid of heat, prone to sweating, and has symptoms of palpitation, bad temper, irritability and sudden eyes.
(3) heart failure
Patients with heart failure are also prone to cold sweat, accompanied by asthma and fatigue, and panting when they are slightly active.
Others belong to sympathetic nerves and are more likely to get excited. Such people tend to blush and sweat when they are nervous.
People who perspire easily must have deficiency syndrome.
1, people with qi deficiency and hyperhidrosis are often accompanied by symptoms of qi deficiency such as limb weakness, mental fatigue and pallor.
Qi deficiency score: 1) Heart-qi deficiency. Symptoms of heart-qi deficiency include palpitation, chest tightness and shortness of breath. 2) lung qi deficiency, lung qi deficiency symptoms, asthma and cough weakness, fear of wind, easy to catch a cold. 3) Deficiency of spleen-qi. Symptoms of deficiency of spleen-qi include abdominal distension, which is worse after eating, eating less, being too lazy to talk, loose stools and yellowish complexion.
The treatment of qi deficiency and hyperhidrosis is mainly tonic such as ginseng and astragalus.
2. Spontaneous sweating due to yang deficiency, the clinical manifestations are soreness and cold pain in the waist and knees, chills and cold limbs, listlessness, long urination or frequent urination at night, and complexion. White or slightly black, pale tongue, white and slippery fur.
Yang deficiency syndrome is mainly treated with yang-warming drugs. Such as aconite, cinnamon and so on.
3, yin deficiency and night sweats, mostly accompanied by symptoms such as five upset fever, hot flashes and night sweats, dry throat and red cheeks, yellow urine, dry stool and so on.
Yin deficiency syndrome is mainly treated with Radix Rehmanniae Preparata, Cornus officinalis and tortoise plastron glue.
There is also a kind of climacteric hyperhidrosis, mainly due to yang deficiency. If it is excessive heat and sweating, it is kidney-yang deficiency with liver depression and qi stagnation, and Sini decoction will soon recover.
I am a person who often perspires easily. I didn't understand it at first. I was told that it was kidney deficiency. I went to buy a lot of Liuwei Dihuang pills. I ate them for more than a year, but it didn't work. I still sweat, sleep and feel weak. Later, I went to the old Chinese doctor and told him that I had kidney yin deficiency and a lot of moisture in my body. I should drink more Poria cocos, soak in water, eat Lycium barbarum, oatmeal, coix seed and so on. I'm much better now. I need to strengthen my exercise.
I am a special person from love sweating, and I have been in love sweating since I was a child. I usually sweat when I have nothing to do, sweating like rain. It really rains when it comes out more.
So, what is the constitution of people who are prone to sweating?
My conclusion: healthy, strong, full of yang, transparent physique.
Specific experience and reasons:
First, it is easy to sweat, which proves that metabolism and circulation function are good. I ate a hot meal and took a sip of hot soup. I didn't wait a minute, and I immediately sweated. The heat of the meal flows to the whole body and reaches the distal toes below. There is sweat and steam on it.
Second, it is easy to sweat, the skin is good, and it is easy to "white back". Sweating can effectively take away the dirt in the pores of the skin, in addition, it can also discharge and take away the moisture, cold and evil spirits in the body. In addition, it may easily take away excess "melanin". Because I often bask in the sun for a period of time every year, my skin is quite tanned. But if you stay indoors for a while and don't go out to bask in the sun, your skin will easily come back white.
Third, it is easy to sweat, which proves that the heat is high. On a hot summer day, I came back to the office from outside, sweating all over. Then I immediately stood in the vertical air conditioner and was blown by the coldest wind of 18 degrees for ten hours. Then the sweat dried up. It's also cool. Never catch a cold. Because "Yang" is strong.
My constitution is very healthy, and I don't smell. It's not how much I am afraid of the heat that makes me sweat easily. My nerves can withstand high temperatures. Sweating is due to the automatic cooling effect of drinking water or sweating in hot days. In addition, sometimes it is easy to sweat even if you are anxious.
Sometimes it belongs to habitual sweating of local sweat glands. For example: sweating on the nose. Not because of the heat, but also because of sweating. When the temperature is below zero in winter, my nose sometimes sweats.
So I think love sweating is a good thing. Prove that metabolism and circulation are good. Generally speaking, I am prone to sweating and belong to: healthy, strong, full of yang and transparent constitution.
Other supplements:
Note: I have "hot sweat", but I know some people are weak and have "cold sweat" I feel wet and sweaty even when I sleep in the middle of the night. These people are not included in my above description. Because they belong to the constitution of "weak night sweats")
