Saline soda is basically the same as the osmotic pressure of body fluids in the human body, and the electrolyte content, especially the salt content, is very similar. Drinking saline soda will not burden the circulatory system of the body. If a large amount of water enters the body, then in order to maintain the electrolyte balance of the whole body fluid, on the one hand, the body will increase excretion and reduce water, on the other hand, it will bring electrolyte from cells, organs and other places to increase the electrolyte concentration of newly added water and maintain the balance of the whole internal environment. However, this adjustment ability is limited. If it exceeds the upper limit, the body will have edema, depending on the situation.

After exercise, the body originally eliminated a lot of electrolytes, as long as it was salt. At this time, it can supplement with salt soda water, which not only supplements water but also supplements salt. Simply drinking water only supplements water, but it will dilute the electrolyte concentration in the body and cause a certain burden to the body. However, if you are in good health, you can drink a proper amount of water, and your body can generally adjust.

However, if you exercise regularly, it is recommended to drink salt soda, which is more thirst-quenching than water.
