Water is very important to human body. Water is indispensable for human cells. Water participates in metabolism, which can regulate body temperature and stabilize the internal environment. Drinking water correctly will bring benefits to the human body, and drinking water incorrectly will bring harm to the body.

How to drink water healthily

1, want to drink fresh water

You can't drink water that has been left for too long, because water left at room temperature for about three days will produce a lot of nitrite. Water left in the blood for a long time will affect the blood's ability to transport oxygen, so choose fresh water and leave it for more than two days before dumping it.

2. drink a glass of water before eating

Drink a glass of water an hour before meals. Drinking water at this time can nourish all tissues and cells of the body. After eating, you can have a lot of digestive juice to help digestion and prevent indigestion and bloating.

3. Drink a glass of water after getting up in the morning

Drink a glass of warm water on an empty stomach after waking up every morning, because there will be water shortage in the body after a night's rest. At this time, drinking water reduces the viscosity of blood, makes the cell function of the body more active, promotes the blood circulation of the whole body, enhances the elasticity of cerebral vessels, and prevents cardiovascular diseases. Besides, getting up in the morning and drinking a glass of water can promote gastrointestinal peristalsis and prevent constipation.

4. Pay attention to the temperature of drinking water.

The temperature of drinking water should be controlled at about 25℃ as far as possible. The water at this temperature has high biological activity, which can directly cross the cell membrane and help moisten the cells. Too hot or too cold water has an impact on health. In addition, you can't gulp it, otherwise it will induce edema.

These three situations remind you not to drink more water.

Patients with severe viral cold should not drink more water.

Keep drinking water after a cold, but don't drink a lot at a time. Drink water intermittently. Drink about one cup at a time, no more than 300 ml, and then drink it after a while. Don't drink one cup after another, it's too heavy for the kidneys. The amount of drinking water a day should not exceed 2000 ml. This can not only maintain the demand for drinking water for the common cold, but also have no effect on respiratory tract infection.

If the heart is not good at drinking water, it is advisable to drink a small amount of water many times.

Experts point out that many heart patients are found to drink a lot of water every day, which is actually very dangerous. Because a large amount of water enters the human body and is absorbed, it will lead to a significant increase in body fluid volume, which will dilute blood and increase blood volume, thus increasing the load on the heart, and the heart has to increase the intensity and speed of blood delivery. It is not a big problem for normal people to increase the workload of the heart, but for heart patients, their originally unsound hearts are often unable to bear such changes, so it is likely to induce or aggravate the condition.

It is not advisable to drink more water for half an hour after a meal.

It is best not to drink a lot of water half an hour after a meal, so as not to dilute gastric juice, dilute gastric acid and damage digestive function. Drinking water after meals and soup between meals can mix digestive juice with food, which has a good effect on digestion and absorption. However, it is unscientific for some people to drink plenty of water after meals. After people eat, food occupies most of the space in the gastrointestinal tract. Drinking plenty of water will fill the stomach and make people feel bloated. In addition, if people eat too much and drink a lot of water, the food in their stomachs will be heavy and their stomachs will sag or swell.
