It's so hot, people sweat a lot or people sweat less, who is healthier?

Summer is hot, everyone feels uncomfortable and tired when the temperature rises. Under high temperature, the difference between people becomes more obvious.

Some people sweat profusely as soon as they step out of the house, and after just a few steps, their clothes are soaked with sweat. But there are also people who seem to sweat very little, and their bodies stay dry no matter how much they exercise. People who sweat a lot tend to be jealous, because those who sweat less seem to have more leisure. Meanwhile, those who sweat less sometimes worry about whether there is something wrong with their bodies, why they don't sweat even in the hot weather.

People who sweat a lot are especially sensitive to temperature.

Sweating regulates body temperature

People who sweat a lot are especially sensitive to temperature, when it gets a little hotter they feel it right away. Walking a few steps makes you sweat, finishing a meal feels like going to a sauna. But don't worry, because sweating is a mechanism to increase the body's ability to withstand heat. Sweat is the body's way of dissipating heat and stabilizing temperature to avoid heat shock and heatstroke. The heat removed by 1 drop of sweat the size of a bean is equivalent to cooling 1 liter of blood (reducing 0.5 degrees Celsius).

You can imagine the human body as a pot, as long as the water continues to evaporate without boiling dry, the pot will not burn. For those who like to sweat in hot weather, this is a pot with more sensitive temperature control and more efficient evaporation and heat dissipation.

Sweating makes the human body more resistant to extreme heat than we thought. One study asked four long-distance runners to walk briskly in dry heat (squares), moist heat (circles), and cool air (triangles). They walked for four hours, ate within half an hour, and then walked for two to three hours. Body temperature, heart rate, and weight loss, or changes in water evaporation, were recorded hourly.

Sweat is the body's way of dissipating heat and stabilizing temperature to avoid heat shock and heatstroke.

The results showed that during a "hurried march" across the hot, dry desert with temperatures reaching 49.6°C, the human body evaporates an average of 1.2 liters of water per hour. As long as they stay hydrated, anyone can survive a whole day in this environment.

In a hot and humid environment (wet air temperature 33.1°C), the evaporation capacity of sweat is weakened, with only about 0.7 liters of evaporation per hour. Although the ambient temperature is lower than the dry air temperature, the body temperature increases more and more rapidly, even exceeding 39°C by the sixth hour, indicating that the body is about to suffer from heatstroke. Simply put: if you can sweat, you can withstand the heat better.

Most people may not challenge their limits by walking fast in the desert, but they still have to go out to work in extremely high temperatures of 39-40°C... If you sweat, your body is trying to save itself. The human body's large air conditioner driven by sweat can be said to be a "limited human reward".

Is sweating more beneficial?

Why do you sweat so much? Because your body feels hotter. Some of the heat is actual body heat: the hotter the weather, the more heat your body produces and the more likely you are to sweat.

Active, muscular, overweight people, as well as teenagers, pregnant women, and people with fast metabolisms tend to sweat more. After exercising and bodybuilding, many people find that they gradually become more sensitive to heat and sweat more. Sedentary people feel naturally cool and rarely sweat.

Part of the heat is the heat that the body feels. The human body also has a temperature set by the temperature-regulating center of the hypothalamus. This temperature is different for each person, as is the sensitivity of the brain and skin temperature as well as the body's ability to regulate temperature. Some people hardly sweat even in hot weather due to nerve damage, blocked sweat glands, etc. (anhidrosis).

The human body has about 2 to 4 million sweat glands.

These conditions of not sweating are actually due to the body's poor regulation function , making you susceptible to heatstroke, which can even be life-threatening.

The human body has about 2 to 4 million sweat glands, and the number can vary from person to person. The level of body temperature regulation also varies.

In addition to environmental heat, spicy foods, severe pain, nervousness, excitement, etc. can also stimulate sweat glands to work. Sweating on the face, chest, and back is often due to heat, while sweating on the palms and soles of the feet is mainly related to emotions.

In general, sweating is a good thing because it helps the body's "air conditioner" work more efficiently. Staying in good shape and getting more exercise can help improve your "sweating" and prevent heatstroke.
