The amount of urine excreted by the human body in one day is about 1 1,500ml, and the total water consumption is about 2,500ml, while the water that the human body can replenish from food and metabolism in the body is only about 1 000ml, so normal people need to drink at least 1 1,500ml of water every day to maintain our normality.
However, if you engage in strenuous exercise, you need to consume more water to prevent dehydration. This is not only to prevent your body from collapsing due to excessive water shortage, but also to ensure that your body is always in the best exercise state. 2~3 hours before exercise, you should drink 2~3 cups (500~700 ml) of water to ensure that your body is not short of water before exercise.
If you are always saturated with water, you don't need to take in too much water, because your body can't store too much water. However, if it is summer, the weather is hot and the consumption is large, the frequency of water replenishment should also be increased appropriately.

Drink plenty of water after exercise;
Exercise and sweating can make the body lose water and electrolytes. Proper hydration is of great benefit to maintaining body fluid balance and promoting physical recovery. However, if you drink a lot of water, it may cause "water poisoning", such as dizziness, vomiting, fatigue, rapid heartbeat and other symptoms, and even muscle spasm in severe cases. In addition, if the water temperature is too low, it will also cause gastrointestinal discomfort and abdominal pain.
For people who exercise for a long time, it is suggested to supplement sports drinks several times before, during and after exercise, and the water temperature should be controlled at 10℃ ~ 20℃. If it is a large amount of exercise, it is necessary to replenish drinks containing oligosaccharides and peptides within 2 hours after exercise, which is conducive to the re-synthesis of muscle glycogen and fatigue recovery.
