People can't live without water. No matter what's wrong with their body, it seems that experts recommend drinking more water. It's better to drink eight glasses of water every day. How many milliliters is it? What's the best time to drink eight glasses of water a day?
How many milliliters is drinking eight glasses of water every day
Eight glasses of water a day generally refers to the total amount of 2000 ml, usually we buy the cup is 250 ml, so it is said to drink eight glasses of water.
But in recent years, some foreign reports put forward different opinions. Some experts point out that you don't have to drink eight glasses of water every day. Drinking too much water can also bring trouble to your body.
The most effective way to drink water in a day is to drink a whole glass of water (about 200-250 ml) in one breath (or once), instead of just two drinks. Only in this way can the body really absorb and use it
Drinking water is the same as caloric intake (supplement as much as you need). At present, there is no scientific evidence that drinking more water can lead to more detoxification. Moreover, if you drink too much water, you will have problems such as electrolyte imbalance (a large number of sodium and potassium ions are lost), and water-soluble vitamins (such as group B and C) are easily lost.
Scientific research has pointed out that the body loses about 1800-2000 ml of water from urine, perspiration or skin evaporation every day. Therefore, healthy adults need to supplement about 2000 ml of water every day. However, 2000ml of water is not necessarily obtained by drinking water, and the water in food should be included. In fact, the foods we eat every day contain a lot of water. For example, more than 90% of most vegetables and fruits are water, and about 75% of eggs and fish are water. Roughly estimated, we eat a meal, at least from food or soup intake to 300 ~ 400ml of water. Therefore, after deducting 1000 ~ 1200ml of water intake from food in three meals, we only need to drink another 1000 ~ 1200ml of boiled water every day, with an average of 2 cups in the morning and 2 cups in the afternoon, even if we do basic work well. However, the demand for water must depend on everyone's environment (temperature, humidity), amount of exercise, physical health and food intake. There is no standard value.
