The human body needs a proper amount of water. However, some people mistakenly believe that the more water you drink, the better, so that more harmful substances and residues can be excreted. In fact, in addition to residues, there will be a lot of nutrients and trace elements excreted with water.
How much water does a person drink a day? The calculation formula is as follows: 35 ~ 40ml of water should be added to each kilogram of adult's body weight. In other words, people weighing 50 kg should be supplemented with 1750~2000 ml of water. This figure also includes water obtained from foods such as soup, fruits and vegetables. Of course, the water demand will increase in hot days and decrease in cold days. However, in the winter heating season, because of the dry climate, you should drink more water, so you should pay attention to replenish water in time in cold days to maintain the balance of water, not to mention that the body needs to heat and moisturize the inhaled cold air. Women who are breastfeeding their children need to drink plenty of water, and pay attention to replenish water after eating, especially those with high fever.
