In the sultry summer, if you are not careful, you will "sweat like rain". Sweating means losing water, so many people think of hydrating first. However, besides water, there is also potassium necessary for human health.

Potassium is an important nutrient and electrolyte in human body, which is mainly stored in cells and plays a very important role in maintaining acid-base balance and osmotic pressure, cell metabolism and neuromuscular excitability.

The safest and most effective way to prevent potassium deficiency in hot weather is to eat more foods rich in potassium, mainly beans, vegetables and fruits. Soybean has the highest content in beans; The vegetables with the most potassium are spinach, potato, yam, celery and lettuce. Among fruits, bananas and oranges have the highest potassium content.

In addition, excessive sweating in midsummer will increase the discharge of water-soluble vitamins, especially vitamin C, which will easily lead to insufficient vitamin content in the body. Therefore, the demand for vitamins in summer is higher than that in other seasons. People can eat more foods rich in vitamin C and vitamin B. Generally speaking, when the body sweats a lot or the body temperature is too high, it is best to replenish water a few times, which can slow down the body's perspiration and reduce the evaporation of water, while sodium supplementation depends on the amount of perspiration.
