If you feel thirsty when you study in college, it means that your body is already in a state of water shortage. Someone on the internet has compiled an optimal drinking schedule. In fact, there is no need to take time to drink. Drink water at least once every 2 ~ 3 hours from getting up to going to bed. Cups are placed in desks, desks and backpacks. Remember to drink two cups often.

According to the dietary guidelines of China Nutrition Society, you should drink about 1.5 liters of water every day, which is almost the so-called "8 glasses of water". But this is just a suggestion. The demand for water varies from situation to situation. When the weather is hot, you are sweating like a pig after exercise, with heavy physical labor, excessive water loss and quick thirst, so naturally you should supplement more. Except for a few cases such as poor cardiac function or renal function before operation, most patients also recommend drinking more water. Especially when college students need water, you should meet it and don't be too rigid about quantity.
