Generally speaking, the amount of water people drink every day should at least be in balance with the amount of water they consume in their bodies. The amount of urine excreted by human body in one day is about 65438±0500ml, and the total water consumption is about 2,500ml when the water evaporated from feces, breathing or skin is added. However, the water that the human body can replenish from food and body metabolism every day is only about 1000 ml. Therefore, normal people need to drink at least 1500 ml of water every day, about 8 cups. How much water a person needs to drink every day varies with activities, environment and even the weather. Drinking more water for normal people will not have much impact on the body, but it may lead to increased urination and inconvenient life.
For some special people, we must pay attention to the amount of drinking water. Patients with edema, heart failure and renal failure should not drink more water. Because drinking too much water will increase the burden on the heart and kidneys, which will easily lead to aggravation of the disease. How much water should these people drink? They should listen to the doctor's specific advice according to their illness. For patients with heatstroke, cystitis, constipation, dry skin and other diseases, drinking more water has a certain effect on relieving the disease. People should also drink more water when they have a cold and fever, because rising body temperature will cause water loss. Drinking plenty of water can promote body heat dissipation and help patients recover. People who exercise a lot will consume a lot of water and should drink more water.
Many people often think of drinking water when they are thirsty, and often gulp water, which is wrong. Drinking water too fast and too hard is bound to swallow a lot of air together, which is easy to cause hiccups or bloating. It is best to put water in your mouth first, and then drink it slowly, especially for people with weak stomach and intestines.
Drink water if you are thirsty. Drink water in moderation between meals, preferably every 1 hour/cup. You can judge whether you need to drink water according to the color of urine. Generally speaking, human urine is light yellow. If the color is too light, you may drink too much water. If the color is dark, it means that some water needs to be added.
