We have to drink water every day, so how much is enough? First ask Dr. Zhang Yi of the Department of Nephrology of the First Affiliated Hospital of Henan University of Traditional Chinese Medicine to debunk the rumors with you, and then tell the truth!
Eight glasses of water a day is actually an empty phrase!
A popular saying a few years ago, widely spread to this day, is that people want to be healthy, they have to drink eight glasses of water a day. The point is, a lot of people believe it! So the question is, how to drink these eight glasses of water? How big is the cup? No one knows. So, eight glasses of water a day is not said!
Drink more water when you urinate yellow, and drink less water when you urinate white?
Later, there was a new saying, how much water should people drink in a day, can not be fixed, why? People are tall, fat and thin. There should be a standard for drinking water, and you can watch urinating. If the urine is yellow, it means that there is a fire in the body, so you need to drink more water. If the urine is white, it means that there is more water in the body, so you must drink less water.
First, the yellow urine does not necessarily mean that there is fire or heat in the body, and secondly, even if there is heat in the body, can you drink unlimited water every day?
How much water to drink in a day, see what The Doctor of Nephrology says!
Why do people drink water every day? Because people need water for all physiological activities. To put it bluntly, water is involved in the body's metabolism. How much water to drink can be measured according to how much urine a person excretes in a day. Under normal circumstances, a person's daily urine output is 1500-2500 ml. Therefore, drinking more water will increase the burden on the kidneys and easily hurt the kidneys. Drink less water, the kidneys are easy to be lazy, and it is not good for the kidneys for a long time.
Therefore, the amount of water required by the kidneys to work properly every day should be "normal urine output + 500 to 700 ml", note that this is the amount of water needed for the whole day, including the amount of water in food. If you're drinking more porridge today, drink less water.
In addition to being involved in metabolism, water can also regulate body temperature, help detoxify, and so on. Therefore, it is not an exaggeration to say that water is the cheapest and most magical medicine in the world! For the sake of our health, so it is better to drink water every day in a normal amount.
