Hualong.com reported at 12:40 on August 24 (correspondent Zeng Li) Chongqing issued a red high temperature warning for ten consecutive days. Some outdoor workers dried pictures of various “salt stains” on their sweaty clothes in their circle of friends. Professor Zhou Renjie, director of the emergency department of Xinqiao Hospital of the Third Military Medical University, pointed out that such “saltiness” is caused by a large amount of salt loss in the human body. Outdoor workers should drink water in time and skillfully to replenish salt in time.
“In hot weather, the human body sweats a lot. In the process of sweating, the human body loses not only water, but also a variety of water-soluble minerals. These water-soluble minerals include trace elements such as sodium, potassium, chlorine and calcium. After the water in the sweat evaporates, these inorganic salt components will dialysis and adhere to the surface of clothes, just like the salt we usually use.” Director Zhou Renjie introduced.
Simple supplement Salt water can’t Health Salt supplement
When the human body is sweating a lot, it also has a great loss of electrolytes in the body. The loss of sodium salt in the body will be accelerated in the sweat. It needs to be replenished in time. Light salt water can not only quench thirst but also replenish energy elements such as potassium and sodium. In this regard, Zhou Renjie pointed out that the trace elements lost in human sweat are not completely equivalent to the salt we usually eat, namely sodium chloride.
Director Zhou Renjie further added that after a lot of perspiration, drinking a glass of light saline can indeed quench thirst and replenish energy, but it is only applicable to workers working at high temperatures or athletes performing outdoor high-intensity sports. Their perspiration level reaches the level that their clothes are all wet, the salt concentration in the blood decreases, and even serious conditions such as muscle spasm may occur, At this time, we should pay attention to supplementing with sports drinks or light saline in advance.
For ordinary people, there is no need to deliberately eat more salt. According to the recommended intake of salt formulated by China Nutrition Association, the daily intake of adults should not exceed 6G, and the salt intake of middle-aged and old people should be about 3G. Excessive salt intake will have adverse effects on the health of blood vessels, heart and kidney. Excessive intake will increase the amount of blood, cause blood pressure to rise, and increase the burden on the heart. People with a history of heart disease may also have myocardial infarction and coronary heart disease.
Therefore, when our daily salt intake has met the normal needs of the human body, if it is not for a lot of sweat, it is unnecessary to deliberately drink more salt water to supplement energy. Cool boiled water and tea can also relieve summer heat and thirst.
expert advice: drinking water requires skill
1. Drink a small amount of water many times
Determine the amount of water to drink according to the amount of water volatilized from the body, such as sweating and urinating. It is appropriate to drink 100 ml to 200 ml each time. The total amount of water replenishment per hour should not exceed 800 ml.
2. Supplement salt in time
You can drink some light salt water or sports drinks containing electrolytes and sugar.
3. Try to drink less ice water
Water at about 10 ℃ can not only reduce temperature and quench thirst, but also won’t hurt the intestines and stomach. It is forbidden to drink water for a long time when working, exercising or going out, and then drink water violently.
