Sweating more vs. less sweat, who has a better body? 3 things you need to know about sweating

The weather is getting hotter and hotter, and the sweat is getting more and more profuse. However, the amount of sweat varies greatly from person to person:

When it's hot, people tend to sweat profusely

But some people, no matter how hot, even if they exercise, they don't sweat much.

What's going on here? Sweating more vs. less sweating, which is better? First we need to understand a problem

Humans are warm-blooded animals, and their body temperature must be maintained at 36.0°C-37.0°C (armpit temperature) in order for the body to function normally.

However, factors such as temperature and exercise in the external environment will increase the body temperature, so in order to keep the body temperature in a constant state, the human body has "developed" a protective mechanism for sweating to dissipate heat.

That is to say, sweating is an instinctive means by which the body regulates body temperature.

Does sweating have other effects, such as detoxification, is it true? fake!

No matter which part of the body sweats, the composition of sweat is similar:

99% is water, and the other 1% includes sodium, potassium, calcium, chlorine, and urea nitrogen.

Although it is said that urea nitrogen is related to the so-called "poison", urea nitrogen is mainly excreted from the human body through urine, and the amount in sweat is almost negligible.

Ps: It is also a rumor that you can lose weight by sweating more. After exercising frantically and sweating, you lose a few pounds immediately, and you lose water in your body, not fat. Drink a few more sips of water, and your weight will come back.

In fact, except for the following differences:

Gender differences, such as men sweating more than women;

Differences in body weight, such as fat people with thick fat, difficult to dissipate heat, and easy to sweat;

Differences in the amount of exercise, for example, people who exercise regularly tend to sweat more than people who don’t exercise;

……

The main reason that determines the amount of sweat that people sweat is the number and development of sweat glands.

There are about 4 million sweat glands in the human body, 75% of which are distributed on the body surface, mainly concentrated in the palms, soles, armpits, chest and face.

However, there are individual differences in the number and main locations of sweat glands:

Those with more and more developed sweat glands tend to sweat easily, and vice versa, they sweat less;

The concentration of sweat glands is different, which will cause some people to sweat easily on the forehead, while others are more likely to sweat on the neck.

Therefore, more sweating and less sweating are mostly caused by the difference in the number and degree of development of sweat glands. As long as you are comfortable, sweating more or less is normal, and there is no so-called difference between good and bad.

However, sometimes even though the weather is not hot and people don't move much, the sweat just rushes out. What's going on?

In addition to excessive sweating caused by temperature, exercise, etc., there are 4 common physiological sweating:

Sweating while eating (taste hyperhidrosis) Taste buds on the tongue have many receptors that, when exposed to food, send signals to the brain to promote perspiration.

When people are nervous and anxious, they sweat more (mental sweating). When people are nervous and anxious, the sympathetic nerves are excited, which leads to more sweating.

Pregnant women sweat more because of changes in the nervous system, increased body temperature, and enhanced sweat gland function. Women are prone to sweating during pregnancy and even one month after childbirth.

Menopause sweating is related to hormonal changes in menopause. Although it is not a disease, if it affects your life too much, you can ask a doctor for help, and there are drugs to relieve it.

The above 4 kinds of sweating are normal

don't worry

Excessive sweating:

After excluding temperature, exercise and the above 4 physiological reasons for sweating, the amount of sweat suddenly increased:

Sweat and fever

At normal room temperature, I don't sweat so much that my clothes get wet

Obviously not hot, but after sleeping, the sheets are wet (night sweats)

It may be caused by diseases, such as hyperthyroidism, hypoglycemia, sudden myocardial infarction or angina pectoris, nervous system diseases, tumors, etc. It is recommended to go to the hospital for further examination.

Ps: In a state of tension and anxiety, sweating is like running water, which may be hand hyperhidrosis (may be related to sympathetic nervousness). It is also recommended to see a doctor.

Abnormally low sweating:

I have been sweating very little all the time, and my body is not uncomfortable. It may be due to congenital lack of sweat glands or underdevelopment, but if the amount of sweat suddenly decreases, especially after hot weather and exercise, be careful that it is a disease. influence. like:

Skin diseases: ichthyosis, reflex dermatitis, skin atrophy, etc.;

Nerve damage: damage to sympathetic nerve, medulla oblongata, pons, etc.;

Vitamin A deficiency, hypothyroidism, etc.;

……

All of them may cause systemic anhidrosis or reduced sweating. Needless to say, see a doctor immediately.

Of course, for most people

Sweating more or less is usually caused by physical differences

Don't be paranoid, fear it's a disease

However, if the amount of sweat changes suddenly (for no reason)

Just be vigilant~
