61% ~ 71% of the components in the human body are water. If a person doesn't drink enough water, all aspects of his physiology will be damaged. This kind of damage is often not easy to detect for a while, and when it is discovered, it has become a serious injury and a disease has occurred. In fact, people are often dehydrated, but they just don't notice it. Middle-aged obesity is the chief culprit of many diseases, and losing weight is a necessary prerequisite for treating various diseases. International obesity treatment experts have come to the conclusion that proper drinking water is the key to lose weight. They pointed out that many people will gain weight and lose muscle if they don't drink enough water, because the body can't metabolize fat because of insufficient water. So, how much water is appropriate to drink a day? The drinking water quantity standard issued by international sports medicine experts shows: drink 1/2 ounce of water per 1 pound of body weight. 1 pounds is about 1.45 kilograms, and 1 ounces is 28.35 grams. According to this calculation, people weighing 65 kilograms should drink 2111 grams of water every day, and those who weigh more should increase their weight, and those who are insufficient should reduce their weight. In this way, in addition to the water content of three meals a day (each person's eating habits are different, the water content is more or less), and drinking 6 ~ 8 cups of water from ordinary glasses is almost the same. This water should be evenly distributed during the day and night, and don't drink too much and too hard for 1 times. Before going to bed, after getting up, 1 hour before lunch, 2 pm and 5 pm, drink 1 cups each. These 5 glasses of water are timed. Especially 1 cup of water in the morning, exercise after drinking, which can dilute the blood and clean the stomach. The rest are irregular and unlimited. Some people may have doubts: will you continue to urinate after drinking so much water? Yes, it's only temporary. Soon, the bladder will adjust itself. At that time, it will increase the amount of urination and reduce the number of urination, and at the same time, the body will get better. Finally, one thing needs to be explained. People with kidney disease and abnormal renal function should not increase the amount of drinking water at will. Whether or not to increase the amount of drinking water should be in accordance with the doctor's advice. The best time to drink water ★ After getting up in the morning, you may get a little dehydrated because you haven't replenished water for some time.
