What is the reason for sweating in summer

Sweating itself is a way to regulate body temperature and dissipate heat, for example, sweating is normal after labor, exercise, emotional excitement and tension. People will sweat, sweating is a physiological function of the body excretion and regulation of body temperature. However, if the way of sweating or the amount, color and smell of sweat changes, it can be an indication of certain diseases and should be taken seriously. So what is the cause of sweating in summer?

Normal physiological phenomenon

It is easy to sweat in summer because of the high temperature in summer, the body metabolism block, the body heat consumption, vascular expansion, skin sweat hole open, body fluid excretion easily, so easy to sweat, this is a normal physiological phenomenon.

The number of small and large glands factor

Physiological studies have found that there are not only gender differences in the number of small glands and large glands, but also individual differences. Therefore, under the same conditions, some people sweat more, while others sweat less.

More autologous body fluids

Individual differences are also expressed in the amount of body fluids. Some people have more body fluids and sweat more when they exercise; others have less body fluids and sweat less when they exercise. The amount of body fluids often depends on the amount of body fat, because fatty tissue contains less water, so fat people have less body fluids than thin people. Although fat people sweat more when exercising, but the ability to tolerate water loss is poorer, that is, the exercise time is not long, fat people will be premature fatigue due to water and salt metabolism imbalance.

Drink a lot of water before exercise

Some people like to drink a lot of water before exercise. Whether or not to drink water before exercise also has an impact on body fluids, and if you drink a lot of water before exercise, you will also increase the amount of sweating due to increased body fluids.

Related to the intensity of exercise

Sweat gland secretion is closely related to the intensity of exercise: the general rule is that the greater the intensity of exercise, the more sweating. This is because as the intensity of exercise increases, muscle activity is more intense and more heat is produced. In order to maintain a normal body temperature, the body must increase sweating to get rid of excess heat, therefore, the greater the intensity of exercise, the more sweating is bound to increase.

Secondary hyperhidrosis

Generally speaking, most people sweat a lot in the summer as a normal physiological phenomenon, but there are a few people who have increased sweating due to physical illnesses, which are called secondary hyperhidrosis, such as hyperthyroidism, endocrine disorders, mental illnesses, etc. This kind of excessive sweating caused by disease must seek treatment for the disease itself, and it is recommended to go to the hospital for examination to clarify the cause before treatment.
