The recommended amount of water intake per person per day is a complex issue related to factors such as an individual's weight, age, gender, physical condition, and lifestyle. In general, adults need to consume about 2 to 3 liters of water per day, but this is not set in stone. For example, an adult weighing up to 80 kg needs to consume about 25 to 3 litres of water, while an adult weighing up to 100 kg would need to consume about 3 to 4 litres. In addition, factors such as age, gender, and physical condition can also affect the amount of water required each day.
In addition to total daily water intake, we also need to pay attention to when and how we drink water. Drinking a glass of water in the morning can help you detoxify your skin, drinking a moderate amount of water in the morning and afternoon can help keep your body active, and in the evening you should drink a moderate amount of water to avoid affecting your sleep. Also, don't wait until you're thirsty to drink water, because thirst is already a sign of dehydration in the body, and at this point the body has already been damaged to some extent.
In terms of drinking water, we should follow the principle of "small amount and many times", and divide the amount of water we drink in a day into several drinks, and the amount of water we drink each time should not be too much. At the same time, we should avoid drinking unhealthy water sources such as raw water, boiling water, and aged water to avoid negative effects on the body.
In short, the recommended water intake per person per day is a matter that varies from person to person, and we need to arrange the drinking time and drinking method reasonably according to our actual situation. Only in this way can we maintain good health and improve the quality of life.
