For a long time, I believe that everyone has heard that the human body needs eight glasses of water every day. Regardless of whether it is scientific or not, we need to know that according to the recommendation of Chinese residents' dietary guidelines, each person should take at least 1200ml of water every day, but this 1200ml is not to say that they should drink it twice at a time, but in different periods of the whole day, 100-200ml at a time. That is to say, drinking water is a person's physiological need. Don't drink water when you feel thirsty, and consciously replenish water on time.
Many people are used to drinking a glass of water before going to bed at night. In response to this practice, some people say that drinking water before going to bed will increase the burden on kidneys and the number of nights; however, some people think that not drinking water before going to bed will increase blood viscosity and easily induce cardiovascular events. In fact, the pros and cons of drinking water before bedtime don't need to be too complicated. For the vast majority of people, drinking water before bedtime is not bad, the key is proper amount. What's more, have you noticed that the advantages and disadvantages of drinking water before going to bed are mainly discussed around the heart and kidney. Now let's see which people are suitable for drinking water before bed and which are not.
For patients with severe renal failure and dialysis treatment, drinking a lot of water before going to bed will increase the load of water in the body, which may lead to swelling and even induce heart failure. People with poor heart function also have the risk of heart failure if they drink too much water before going to bed. However, this is only limited to people with poor heart and kidney function, and it can only happen if they drink a lot of water.
In general, drinking water at night will not increase the burden on the kidney, especially in the hot summer, water loss in the body is fast, and it is very important to keep enough water. However, just because people don't drink water before going to bed doesn't mean that other people's water at night is just enough and healthy.
For some cardiovascular and cerebrovascular patients and some elderly people, if they don't drink water all night, their blood viscosity will increase. If the blood is too thick and concentrated, it will easily lead to thrombosis and cause cardiovascular and cerebrovascular diseases (such as angina pectoris, myocardial infarction, cerebral thrombosis, etc.). Therefore, for the high-risk population of cardiovascular and cerebrovascular diseases, we can drink a glass of water before sleeping and at night to dilute the blood concentration and reduce the incidence of cardiovascular and cerebrovascular diseases. In addition, for diabetic patients, maintaining a certain amount of water is also conducive to the control of blood sugar.
In a word, water is an important part of diet, a necessary material for life, and plays an important role in life activities. And the amount of drinking water will be different because of different people's constitution, environment, climate, amount of exercise and work. For example, people who work outdoors in summer should drink at least 2000-3000ml because they sweat a lot, while in winter, 1200-1500ml is enough. Insufficient or excessive drinking water will do harm to human health. As a healthy person, if you have the habit of drinking water before you go to bed, it's OK to have a proper amount.
