Experts suggest that drinking water at one time should not exceed 200ML, but the survey results show that 84.6% people drink more than 200 ml on average. In addition, 74.9% people drink less than 6 times a day, and nearly13 people drink less than 1200ml a day.

Never drink water when you are thirsty. Drink a small amount many times. According to experts, besides regular drinking water, irregular drinking water is also very important. Because the body's thirst response mechanism is not very sensitive, generally when the body lacks 2% water, it will feel thirsty. Therefore, it is necessary to drink saliva from time to time, but it is not advisable to drink too much water at a time, and it is advisable to drink about 200 ml each time.

In addition, the amount of drinking water will be different because of everyone's physique, environment, climate, exercise and work. For example, people who work outdoors in summer have to drink at least 2000-3000ml of water because they sweat a lot, while 1, 200- 1, 500 ml is enough in winter.
