The correct way to drink water:

First, it is best to drink warm boiled water

On the one hand, the intake of cold drinks will make the gastrointestinal mucosa suddenly cold, which will make the originally open capillaries contract and make the smooth muscles spasm, which may cause gastrointestinal discomfort or colic or even diarrhea.

On the contrary, some people like to drink boiling water. Too hot food entering the esophagus will destroy the esophageal mucosa and stimulate mucosal proliferation, and induce esophageal cancer, which has been the conclusion of the medical profession.

therefore, the optimum temperature of drinking water is 1℃-3℃.

2. Don't gulp water

When thirsty, many people are used to "gulping" and drinking heavily. Little did they know that this drinking method is not good for health. Small amount, multiple times and slow drinking are the three basic principles for drinking water correctly.

a reasonable way to drink water should be to put a mouthful of water in your mouth and swallow it slowly several times, so as to fully moisten your mouth and throat and effectively relieve the feeling of thirst.

Third, the amount of water to drink varies from person to person

Healthy people can judge when to replenish more water by urine color: the normal urine color should be light yellow, and if the color is too dark, it should be replenished; If the color is very light, it may be too much water.

for patients, drinking water needs to be different from person to person. For example, patients with heart disease should increase their intake of water every day when they show insufficient coronary blood supply, so as to avoid the occurrence of myocardial infarction due to high blood viscosity. However, when patients show heart failure, they should not drink too much water. Because drinking too much water will increase the burden on the heart, leading to aggravation of the disease. In order to avoid increasing the burden on the kidneys, patients with acute nephritis and renal failure should not drink too much water. When a cold has a fever, the water lost from the respiratory tract is more than usual. In addition, the temperature of the fever increases, and the water evaporated from the skin also increases. It is necessary to replenish more water appropriately.

Fourth, don't drink boiled water overnight

This is because the nitrogen-containing organic matter in boiled water for a long time will be continuously decomposed into nitrite, and at the same time, it is inevitable that the intervention of microorganisms will accelerate the decomposition of nitrogen-containing organic matter. The harm of nitrite to the body is well known. It has a strong ability to combine with hemoglobin in the body, which will hinder the normal oxygen transport function of blood. Therefore, it is best to drink boiled water the same day.

In addition, many families are used to drinking bottled water now, and seemingly well-sealed bottled water should be drunk within three or four days. Because the bottled water is opened for a long time, bacteria will sneak in along the water inlet, and the water dispenser will form negative pressure when it comes out, and it will inevitably suck in some air, and bacteria and microorganisms in the air will also "take advantage of it". If you don't drink it in a short time, the bacteria will exceed the standard and the pure water will no longer be pure.
