The purpose of drinking water is to replenish the water lost by human metabolism. Adults excrete about 2500 ml of water from urine, feces, sweat and exhaled breath every day, taking away all kinds of toxins and wastes produced by metabolism in the body. Therefore, only when people drink more than1500ml of water, plus the water contained in meals, can the balance of water intake and outflow be achieved. The human body is short of water for a long time, and the toxins and wastes produced in the metabolic process are not discharged in time, which will endanger health, such as constipation, dry skin, dry hair and bad breath. , but also prone to urinary calculi. Lack of water leads to the increase of blood viscosity, promotes arteriosclerosis and increases the chance of cardiovascular and cerebrovascular embolism.
The amount of water you drink every day depends on factors such as temperature and exercise. The reliable indicator of whether the human body is full of water is urine volume. If the urine discharged within 24 hours is greater than 1000 ml, the amount of drinking water is appropriate, otherwise it is insufficient.
The most beneficial drinking water for health is: light tea and boiled water at 20 ~ 50℃, because their tension, density and biological activity are closest to blood and cell fluid. Don't drink water when you are thirsty, and don't binge drink after exercise. Get into the habit of drinking water regularly.
