Is sweating more really good for your health?

The weather is getting hotter and hotter. I sweat a lot as soon as I go out. I feel uncomfortable all over. But some people say: sweating more is actually good. It is good for detoxification and weight loss. Is it really so?

Why do people sweat?

The hypothalamus in our brain is the body temperature regulation center. When the ambient temperature is low, it will instruct brown adipose tissue to produce heat, skeletal muscles to shiver (shiver when feeling cold), and constrict blood vessels to start the "heat production mode".

When the ambient temperature rises, it will start the "cooling mode" by accelerating the evaporation of water and dilating blood vessels. The sweat glands will continue to sweat, and when the sweat evaporates, it will take away heat and cool the body down.

In addition to cooling down, sweating can also maintain the harmony of the body, for example, balancing trace elements in the body and maintaining skin health.

Can sweating more help detoxify?

It is said that sweating can speed up the excretion of toxins from the human body, and some people want to prevent illness by sweating more, but until now there has been no evidence to support these claims.

99% of sweat is water, and less than 1% is sodium chloride, potassium, urea nitrogen, etc. It can almost be regarded as pure water.

To a certain extent, sweating can indeed excrete some metabolic waste and toxins from the body, but the effect on other excretion routes of the body (such as excretion from the liver, kidneys, and gastrointestinal tract) is very small and is not the main excretion route of the human body, so sweating more will not have a significant detoxification effect.

Can sweating more help you lose weight?

When sweating quickly, the most lost substance is water, followed by electrolytes, sodium chloride and a small amount of potassium. Sweating too much in a short period of time may affect the balance of water and electrolytes in the body, leading to uncomfortable feelings such as lack of strength, dizziness, cramps, etc.

In addition, sweating will lead to a decrease in urine volume. If you do not drink water, it will lead to the accumulation of some "toxic" substances that are mainly excreted from the kidneys, such as uric acid, creatinine, etc.

Why do some people sweat more and some less?

How much each person sweats depends mainly on the activity of the body's sweat glands to the sympathetic nerves and the strength of the body's response to the stimulation of the sympathetic nerves. It is mainly related to genes and one's own physical condition.

Generally speaking, men sweat more easily than women; the heavier a person is, the more they sweat.

Some sweat cannot be released at will

Sweating is a physiological phenomenon that is beneficial to the body and is used to regulate body temperature. However, some abnormal sweating may be caused by certain diseases and you need to consult a doctor as soon as possible.
