So

Which of these rumors are true and which are false?

Sweating is a common occurrence

But sweating more or less is a science.

today

Let's talk about sweating.

Make it clear once

Why do we sweat?

Sweating is a physiological function of the human body to excrete and self-regulate body temperature. Sweating methods are mainly divided into four types : thermal sweating, mental sweating, taste sweating, and exercise sweating .

Generally speaking, the sweat discharged by the human body is colorless and transparent, and has no strong odor.

What are the main components of sweat?

The components of sweat include water, sodium chloride, potassium, lactic acid, urea, ammonia, amino acids, protein, proteolytic enzymes, histamine and prostaglandins , among which the water content is as high as over 99%, and other substances account for 0.5% to 1%.

What determines how much you sweat?

How much a person sweats is mainly determined by many factors, including ambient temperature, genetics, metabolism, weight, mood, etc. Certain special periods, such as menopause and pregnancy, can also affect the amount of sweat a person produces.

1

Ambient temperature

The human body temperature is generally between 36 and 37 degrees Celsius. If the external environment temperature is too high, it will cause the body temperature to rise. At this time, the human body will regulate the body temperature by dissipating heat through sweating through the skin to avoid health damage caused by high or low body temperature.

2

Genetics

The amount of sweating is closely related to sweat glands, but the number and distribution of sweat glands are different for each person. Generally, people with more and more developed sweat glands are more likely to sweat.

3

Metabolism

People with a fast metabolism who exercise a lot generally sweat more than people with a slow metabolism who don't exercise. Also, young people sweat more easily than older people.

4

Fat or Thin

Fat people have a high fat content, which has a thermal insulation effect, but has poor thermal conductivity, making it difficult to dissipate heat. The thicker the fat, the more difficult it is to dissipate heat. When the heat generated by metabolism in the body is difficult to dissipate, the human body will dissipate heat through sweating.

5

mood

When people are nervous or excited, their sympathetic nerves will become excited, and the secretion of sweat glands will increase, causing the body to sweat more.

6

Special Period

In addition to the above factors that affect how much the human body sweats, the amount of sweating the human body also changes during special periods such as pregnancy and menopause.

For example, during pregnancy, the sweat gland function of pregnant women will be enhanced, and the vigorous secretion of sweat glands will lead to increased sweating.

During menopause, some women experience changes in their sex hormone levels, which may also cause symptoms such as excessive sweating, fever, and rapid heartbeat.

As mentioned above, most people's excessive sweating is physiological and has nothing to do with disease. However, it should be noted that abnormally heavy sweating, not sweating no matter how hot it is, or a significant change in the color or smell of sweat may also mean a precursor to certain diseases and need to be taken seriously↓

1

Abnormal sweating

Because everyone's physical constitution is different, there is no uniform standard for "how much sweating is considered excessive."

But if you suddenly experience a surge in sweating, or if you're sweating profusely in an environment where you shouldn't be sweating, you should be alert.

For example, you are quietly sitting in an air-conditioned room, eating watermelon, watching TV series, but your nose is sweating, your head is hot, and your hair is soaked, or you sweat so much that the sheets and quilts are soaked at normal room temperature. At this time, you can see that the sweating is somewhat abnormal. It may be hyperhidrosis or certain diseases in the body, such as hyperthyroidism, diabetes, pheochromocytoma, hypoglycemia, etc. Most patients with these diseases have symptoms of sweating easily. If these abnormal conditions occur, it is recommended to go to the hospital for examination in time.

2

No matter how hot it is, I don't sweat

For people with fewer or underdeveloped sweat glands, it is usually normal to sweat less.

However, if your body is hot but you don't sweat in high temperatures or after strenuous exercise, you need to consider whether you have anhidrosis, hypohidrosis, hypothyroidism, or other diseases .

In addition, you should also be alert to whether you have suffered from the fatal heat stroke , which is severe heatstroke. If rescue is not timely, the mortality rate can reach about 70%.

3

Sweat odor, color

Under normal circumstances, the sweat discharged by the human body has no strong odor and is colorless and transparent.

If there is color in the sweat, such as yellow sweat, red sweat, green sweat, black sweat , or if there is a strong fishy odor or it is particularly sticky , it is recommended to go to the hospital for examination in time, and the doctor will make a comprehensive judgment and make a diagnosis and treatment.

in conclusion

The amount of sweating has nothing to do with the strength of your physical constitution. 99% of what you sweat out is water, and it has no effect on detoxifying or beautifying the skin.

If you sweat a lot at one time due to exercise or certain environmental factors, it is recommended to replenish water in time to avoid electrolyte imbalance in the body, which may lead to dehydration, hyponatremia, shock, etc.

If you sweat profusely even when sitting still at normal room temperature, you should be alert to diseases such as hyperthyroidism, diabetes, pheochromocytoma, hypoglycemia, etc.

If you feel hot but don't sweat in high temperatures or after strenuous exercise, beware of hypohidrosis or anhidrosis, or be even more careful of fatal heat stroke.

In short, if abnormal sweating becomes severe or accompanied by other serious symptoms, seek medical attention immediately.
