Is it good to sweat easily in summer?

Everyone's physical condition is different. Some people sweat frequently in the hot summer, but some people don't sweat easily. When the weather is hot, it is normal for people to sweat. However, some people worry whether excessive sweating will have adverse effects on the body. Therefore, people often have doubts about the problem of sweating in summer. Will physical weakness also lead to excessive sweating in the summer? Is it good to sweat easily in the summer?

Sweating can be divided into physiological and pathological types. For example, sweating in hot weather or when doing a lot of exercise is mostly a physiological phenomenon. There are two most common pathological causes of excessive sweating:

One is night sweats, which occurs when you sweat involuntarily during sleep. The other type is spontaneous sweating, which occurs during the day without any cause for labor, thick clothing or heat, or profuse sweating after a little exercise. The main reasons for spontaneous sweating are physical weakness or after a serious illness. Traditional Chinese medicine believes that this is caused by "insufficient lung qi and weak Wei Yang". The treatment should be based on the principle of "tonifying the lungs and replenishing Qi, consolidating the exterior and nourishing Yin". You can choose to take Buzhong Yiqi Pills and Shengmai Drink to nourish the soil and produce gold, replenish qi and restrain sweat, or chew American ginseng and ginseng, etc. You can also choose Shengmai Powder and Yupingfeng Pills with modifications.

Sweat gland secretion is closely related to exercise intensity: the general rule is that the greater the exercise intensity, the more sweat you produce. Because as the intensity of exercise increases, muscle activity becomes more intense and more heat is produced. In order to maintain normal body temperature, the human body must increase sweating to dissipate excess heat. Therefore, the greater the intensity of exercise, the more sweating will inevitably increase.

How much you sweat is primarily related to individual differences:

As we all know, sweat comes from the secretion of sweat glands, and there are a lot of sweat glands. Millions of sweat glands can be roughly divided into two categories:

One type is the eccrine sweat glands, which are widely distributed under the skin all over the body, with an average of about 300 per square centimeter and a total of about 2.3 million in the body. When exercising or the external temperature rises, the human body mainly relies on these sweat glands to sweat. Physiologists call this type of sweating thermal sweating.

The other type is the apocrine sweat glands, which are distributed under the skin in the armpits, nipples, vulva and other parts. When people are frightened, excited or humiliated, it is mainly this gland that sweats. Physiologists call this type of sweating neurogenic sweating. Physiological studies have found that the number of small glands and large glands varies not only between genders, but also between individuals. Therefore, under the same conditions, some people sweat more and some people sweat less. In addition, individual differences are also reflected in the amount of body fluids. Some people have more body fluids and sweat more when exercising; some people have less body fluids and sweat less when exercising. The amount of body fluid often depends on the body fat content. Because adipose tissue contains relatively less water, fat people have relatively less body fluid than thin people. Although fat people sweat a lot during exercise, their ability to tolerate water loss is relatively poor. In other words, if they do not exercise for a long time, fat people will become tired prematurely due to water and salt metabolism disorders. Whether or not you drink water before exercise also affects body fluids. If you drink a lot of water before exercise, the amount of sweating will increase due to the increase in body fluids.

Therefore, the amount of sweating varies from person to person, so there is no need to worry. It is normal to sweat a lot during exercise. Sweating is the body's way of maintaining a normal body temperature by secreting body fluids through the sweat glands under the skin to evaporate and take away the excess temperature in the body in order to prevent problems caused by excessive body temperature. The temperature is high in summer, which causes the human body's internal and external body temperatures to be too high. Organs are prone to edema when they are at too high a temperature, which is life-threatening. Therefore, in summer, the human body secretes a large amount of body fluids to maintain normal body temperature. Some people sweat more or less for many reasons. For example, obesity. Body fat is like a sponge for keeping warm and has a strong thermal insulation effect. The human body also generates a lot of heat due to exercise, and the fat in the body just hinders the dissipation of this heat. In order to dissipate heat as quickly as possible, the body sweats profusely. But this is not necessary for thin people.

But there is another reason, which is calcium deficiency. Many people know that sweat contains a lot of sodium chloride, so salt should be supplemented if you sweat a lot, but some people ignore the need to supplement calcium after sweating. According to research, every 1000 ml of sweat contains 1 mg equivalent of calcium. Under normal circumstances, the loss of calcium in sweat is only 15 mg per day, which is not very important. However, people working in high temperature environments in summer lose more than 100 mg of calcium in sweat per hour. This amount accounts for almost 30% of the total calcium excretion, which can easily lead to hypocalcemia, manifested as cramps in the patients' hands and feet, muscle twitches, and long-term calcium deficiency can cause adults to suffer from rickets, easy fractures, and frequent back and leg pain. In order to prevent hypocalcemia after sweating, workers who work in high temperatures should take in enough calcium in their daily lives. Foods rich in calcium include milk, dairy products, green leafy vegetables, fish, seafood and other foods. Vitamin D promotes calcium absorption. Foods rich in vitamin D include cod liver oil, animal liver, egg yolk, etc. Increased exposure to sunlight can also increase vitamin D levels in the body. In short, in the summer, exercising more and strengthening your physical fitness can help you avoid physical weakness and excessive sweating.
