Is it good to sweat a lot in the dog days of summer?

The dog days of summer are the hottest part of the whole summer. In such weather, it is particularly hot and stuffy, and everyone will sweat unconsciously. Some people like to turn on the air conditioner during the dog days of summer, because only the coolness of the air conditioner can save the sultry weather. However, sweating during the dog days is normal, but some people sweat excessively. For example, clothes, hair, and face are often wet. I will be very worried about this issue: Is it good to sweat a lot during the dog days of summer?

1. What are the benefits of sweating more during the dog days?

1. Maintain the balance of various organs and tissues

Professional doctors believe that proper sweating is the result of the body's regulation and helps maintain the balance of various organs and tissues in the human body.

2. Detoxification and cancer prevention

Research data show that sweat is one of the ways to excrete harmful substances such as arsenic, cadmium, lead, and mercury from the body. Heavy metal components can be detected in sweat at concentrations comparable to those in urine, and sometimes even higher than in urine. Therefore, sweating is also an effective way to detoxify and prevent cancer.

3. Good for the skin

In summer, oil secretion is vigorous, and many people often get acne on their faces, backs, etc. Sweat can remove toxins that clog the pores. Sweating more in the summer can help you eliminate blackheads and pimples on your skin, making your skin firm, delicate and shiny.

4. Improve immunity

Studies have found that the antimicrobial peptides contained in sweat can effectively resist viruses, bacteria and fungi. Exercise for 30-45 minutes every day, let your body sweat slightly, and persist for a period of time, which can effectively enhance your own immunity and improve your ability to fight bacteria and viruses.

5. Improve memory

Studies have confirmed that sweating during exercise can have a positive effect on the brain, significantly improving memory and concentration. Moreover, sweating will keep the body's cells in an exuberant state, maintain mental concentration, enhance memory, and make the brain more active.

6. Prevent colds and other diseases

The antimicrobial peptides contained in sweat can effectively protect against viruses, bacteria and fungi; they can enter the cell membrane of bacteria and break them down. Therefore, proper sweating can enhance the body's immunity and prevent summer colds.

7. Prevent stones

Sweating can effectively excrete salt from the body and retain calcium in the bones, preventing inorganic salts such as magnesium phosphate from crystallizing and depositing in the body, thus avoiding the formation of stones.

Dog Days

2. Misunderstandings about Health Preservation in the Dog Days

1. Sweating a lot is good for your health

On the one hand, sweating in the summer can evaporate heat and maintain a constant body temperature; on the other hand, it can excrete a variety of harmful metabolic wastes, such as lactic acid, carbonic acid, creatinine, urea, and bacterial toxins. Therefore, as long as you can sweat a little and have smooth urination in the summer, you are less likely to get sick. If there is no sweat and little urine, it is often a precursor to heatstroke. The sweat glands of the elderly atrophy, so they are more susceptible to heatstroke.

2. Open doors and windows for ventilation and coolness

On hot summer days, the temperature outside is very high, and sometimes even the wind outside is hot. At this time, opening the doors and windows will make the temperature indoors and outdoors the same. Therefore, if the outdoor temperature is very high in summer, the doors and windows should be closed before 14:00 when the temperature is highest to keep the indoor temperature at a low level. Open the doors and windows in the evening and the room will feel cooler.

3. Drink plenty of water after exercise

Exercising in summer will inevitably cause a lot of sweating. If you exercise for a long time, your body will lose a lot of water and you will inevitably feel dry mouth and tongue. Some people drink a lot of water after exercise. First, they feel refreshed. Second, they think drinking a lot of water can replenish the body's needs as soon as possible and balance the body fluids. In fact, this approach is wrong. When people exercise, a large amount of blood in the body is retained in the muscles of the limbs. If you drink a lot of water immediately after exercise, it will inevitably cause some blood vessels in the gastrointestinal tract to contract sharply, weaken the absorption capacity, make people feel heavy and bloated in the stomach, hinder the activity of the diaphragm, and affect normal breathing. Therefore, after summer exercise, you should replenish some water, especially salt water, and avoid drinking large amounts of water quickly.

4. Go shirtless to keep cool

During the hot and humid dog days of summer, some people always like to expose their backs, thinking that it will keep them cool, but this is not necessarily the case. From a physiological point of view, human body temperature regulation depends not only on skin evaporation, but also on skin radiation. It has been measured that in an environment with a temperature of 18-28 degrees Celsius, 70% of human body temperature is dissipated through skin radiation, convection and conduction; when the temperature reaches 35 degrees Celsius, body temperature is mainly dissipated through skin evaporation; when the temperature continues to rise, the skin not only cannot dissipate heat through radiation, but also absorbs heat from the external environment. Therefore, if you go shirtless at this time, it is easy to absorb heat, and instead of feeling cool, you will feel even more stuffy.

5. Don’t stay up late on summer nights

Some people believe that in summer, going to bed when the temperature drops in the second half of the night and getting up late the next day can help people get better rest. However, according to the rules of the human body's "biological clock", the best time to sleep is 10-23 o'clock. 5-6 o'clock in the morning is the "climax" of the biological clock, and it is best to get up at this time. Therefore, you should still get up and live on time in summer.
