In fact, there is no need to worry too much about the advantages and disadvantages of drinking water before going to bed. For most people, there is no harm in drinking water before going to bed. The key is appropriateness. But what groups can drink water before going to bed and what can't? Patients with severe renal failure and dialysis treatment should not drink water before going to bed; Cardiovascular and cerebrovascular patients, diabetics and some elderly people can drink water before going to bed, which helps to slow down the viscosity at night.

First, drinking water is a human physiological need.

All along, I firmly believe that everyone has heard the saying that the body must drink eight glasses of water every day. Whether it is a scientific research or not, we must understand that according to the strong recommendation of Dietary Guidelines for China Residents, each person should consume at least 1.200ml of water every day, but this 1.200ml does not mean that you should drink it twice at a time, but it is only divided into 24 hours and 65,438 at a time. In other words, drinking water is a human physiological need. You don't have to feel thirsty to drink water, but you should replenish water on time with a purpose.

Second, is drinking water before going to bed up to standard?

1. For patients with severe renal failure who have started dialysis treatment, drinking plenty of water before going to bed will increase the water load in the body, which may lead to edema and even chronic heart failure.

2, people with poor cardiopulmonary function, drinking too much water before going to bed is also the risk of heart failure. But this is limited to people with poor heart and kidney function, and it can happen in many cases of drinking water.

3. Drinking water properly before going to bed at night is not easy to improve the pressure of renal function, especially in hot summer, when the body's water flows out quickly, it is very important to keep good water. However, most people don't drink water before going to bed, which doesn't mean that others drink more water at night, which is good for their health.

4. For some cardiovascular and cerebrovascular patients and some elderly people, if they don't drink water all night, their blood night viscosity will increase. If blood night is too thick, it is easy to cause thrombosis and cardiovascular diseases (such as myocardial infarction, myocardial infarction, cerebral hemorrhage, etc.). Therefore, for the key targets of cardiovascular diseases, we can drink a glass of water before going to bed and at night to dilute the blood concentration at night, thus reducing the prevalence of cardiovascular diseases.

For diabetic patients, keeping a certain amount of water is also beneficial to control blood sugar.

In a word, water is a key component of diet, an essential chemical substance for all life and plays a key role in life activities. How much water to drink every day will be different because of everyone's physical quality, natural environment, climate, exercise intensity and work. For example, people who work in the fields in summer have to drink at least 2000-2500l of water every day because they sweat a lot, while 1200- 1500Ml in winter is enough. Drinking too much or not is harmful to health. As a normal person, if you have the habit of drinking water before going to bed, you can do it properly.
