Reasons for Sweating | Is it a good thing to sweat easily? Sweating can cool down/detoxify/lose weight | am730

On a hot day, you will sweat profusely even if you move even a little bit. Even if you take a shower many times, you will be sweating all over. Some people sweat profusely and lightly; some people sweat less easily; some people sweat thickly and emit strong body odor; some people’s sweat is refreshing and odorless. Sweating is a normal physiological phenomenon of the human body. It can regulate body temperature, take away waste from the body, consume calories and discharge water to achieve weight loss.

Normally speaking, “not sweating” is not a good thing. Does sweating so easily mean health? It turns out that different sweating locations are hiding disease warnings; however, sweat itself can be divided into “good sweat” and “bad sweat”. In addition, through sweat gland training, can sweat be made “better”? Known as “Dr. Sweat”, a Japanese medical doctor who specializes in the study of sweating syndromes will analyze the doubts about sweat with everyone.

Sweating protects the brain

Sweating is a very important physiological phenomenon for humans. The main function of sweat is to prevent the body temperature from rising due to the heat of vaporization during evaporation and to keep it constant. Thermoregulation is about protecting cells and organs in the body, especially the brain, from the effects of high temperatures. Because the brain is very sensitive to heat, when you feel hot, your body will sweat to regulate body temperature and prevent overheating and damage to the brain.

There is a difference between good and bad sweat

When a person is born, there are about 5 million sweat glands in the body, but not all sweat glands are actually “active”. For the Japanese, the average number of sweat glands that produce sweat is about 2.3 million. In other words, more than half of the sweat glands are dormant.

Sweat comes from blood. Sweat glands absorb plasma, but not blood cells, and excrete it out of the body in the form of sweat. Sweat glands have an important filtering function, expelling excess salt, minerals and other waste from the body. At the same time, sweat is reabsorbed by the body to prevent excessive excretion of ingredients. Theoretically, if the sweat glands perform their filtering function effectively, most of the remainder of the sweat will be water. This smooth and odorless product is “good sweat.”

On the contrary, if the filtration function of the sweat glands is not good, thick and sticky “bad sweat” will be produced, which is due to the residual plasma components in the sweat. This kind of sweat is not conducive to preventing heat stroke because it is difficult to evaporate and reduce body temperature. Moreover, “bad sweat” makes it easier for bacteria to breed, causing odor to occur immediately after sweating.

Come up with “good sweat” to train sweat glands

Sweat is sticky and thick, reflecting abnormal function of the skin’s sweat glands. Sweat glands need to be used regularly to prevent them from losing their function. If you often stay in an air-conditioned room because you don’t want to sweat, or if you rarely sweat due to lack of exercise, your sweat gland function will decline rapidly.

In order not to hinder the development of sweat glands, it is important to allow them to function properly and sweat profusely. By performing “sweat gland training”, weakened sweat glands can be restored to a certain extent. The method is to pour hot water of 42 to 43°C into the bathtub and soak only the elbows and knees for about 15 minutes. In this case, you should sweat within about 5 minutes, and then rely on the fan to evaporate the sweat and naturally lower your body temperature. Repeatedly every day, the function of the sweat glands will gradually increase, making it easier to produce “good sweat”.

Sweat odor and sweating location are “barometers” of health

Men have more sweat glands than women, and male hormones activate the secretion of sebaceous glands, making sweating more troublesome for men. In addition, men over 40 years old tend to have an “old man’s smell” when they sweat. This is due to oxidation of sebaceous glands. These are called “metabolic odors” and reflect that cholesterol in the body may be oxidized, increasing the risk of diseases related to lifestyle habits. Therefore, if you often have body odor, there must be something wrong with your body.

Sweating location

In addition, different locations of sweating also reflect warning signs of different diseases. For example:

1. Only sweats on the face:Hormonal changes in women during menopause lead to autonomic nervous system disorders, resulting in hot flashes and profuse sweating on the face. In addition, people with Parkinson’s disease suffer from autonomic nervous system disorders and low body temperature regulation function, resulting in cold limbs. On the contrary, the areas above the chest, especially the face, are prone to sweating a lot.
2. Sweating at the hairline on the back of the head:Sweating at the hairline on the back of the head is a “cold sweat” caused by hypoglycemia. It is often accompanied by shivering, dizziness, and nausea. At this time, eat candy immediately to replenish sugar.
3. Sweat is concentrated in the armpits:It represents mental stress and worries, which need to be relaxed to relieve.
4. Drenched and sweating:Suffering from hyperthyroidism (hyperthyroidism) will make the whole body prone to sweating, intolerance to heat and fatigue, and symptoms such as heart palpitations and weight loss may occur.
5. Sweat concentrated in the upper body:Diabetes can cause neuropathy, causing the lower body to be unable to perspire normally, and sweat will be transferred to the upper body, causing excessive sweating in the upper body.
6. Sweating during night sleep:This condition is also called “night sweats.” If you continue to sweat during deep sleep, it means that long-term exposure to emotions or stress has oppressed the heart, stimulating the sympathetic nerves, causing involuntary cold sweat, and making the body weak after sweating. If the condition persists, it reflects the risk of leukemia, tuberculosis or even cancer.
