Why do I sweat when I exercise?

In real life, many people sweat after exercise, especially those who do not exercise for a long time. They will sweat a lot. Exercise will consume some water and excess fat in the body, and fat and toxins and waste in the body will be discharged from the body with sweat. While exercising, it will constantly stimulate every part of the body, causing the body to feel hot and sweaty. So why do you sweat when you exercise? Let’s take a look at it together below.

It is normal to sweat a lot during exercise

Sweating is a way for the human body to maintain a normal temperature. In order to prevent the body temperature from being too high and causing problems, the sweat glands under the skin secrete body fluids, which evaporate and take away the excess temperature in the body.

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.

This is the end of the introduction about why you sweat when you exercise. I believe that you all understand why you sweat when you exercise. When exercising, you should replenish your body with sufficient water in time. Due to excessive sweating, the body will become dehydrated, so at this time you should drink some water before exercising.
