First of all, the human body is prone to sweating when working in high-temperature places. The sweat contains salt. When the human body loses too much salt, the physical strength will decrease and the concentration of cell fluid in the human body will increase. , at this time, light salt water is needed to replenish the water lost in the cell fluid and replenish the salt needed by the human body. Carbon dioxide will play a certain supporting role. Carbon dioxide absorbs heat from the human body and is eliminated, making the person feel cool.

Secondly, sweating will take away salt, such as sodium ions, and drinking salt soda can replenish salt.

Hope it helps you...
