The high temperature in summer affects the body's internal and external body temperature, and the organs are prone to edema, which is life-threatening. Therefore, in summer, the human body will secrete a lot of body fluids to keep the body temperature normal. And some people sweat more and sweat less for many reasons. Like obesity. Body fat is like a sponge used to keep warm, which has a strong insulation effect. The human body also produces a lot of heat because of exercise, and the fat in the body just hinders the emission of these heat. In order to dissipate heat as soon as possible, the body uses a lot of sweating to dissipate heat. Thin people don't have to do this.
But there is another reason, and that is calcium deficiency. Many people know that sweat contains more sodium chloride and should be supplemented with salt when sweating, but they ignore the need to supplement calcium after sweating.
According to research, every 1000 ml of sweat contains 1 mg equivalent of calcium. In normal times, only 15 mg of calcium is lost from sweat every day, which is not very important. However, people who work in high temperature environment in summer lose more than 100 mg of calcium from sweat every hour, accounting for almost 30% of the total calcium output, which easily leads to hypocalcemia.
In order to prevent hypocalcemia after sweating, high-temperature workers should take enough calcium in their lives. Foods rich in calcium include milk, dairy products, green leafy vegetables, fish, seafood and other foods. Vitamin d can promote the absorption of calcium. Foods rich in vitamin D include cod liver oil, animal liver and egg yolk. Increasing sunlight exposure can also increase the content of vitamin D in the body.
In short, in summer, you can avoid weakness and sweating by exercising more and strengthening your physique.
