Is it good to drink water before bed?

Many people believe that drinking water before going to bed will cause them to get up at night or have a "swollen face" the next day, so they try to avoid drinking water before going to bed. But in fact, drinking a few sips of water before going to bed is good for our health. When we are asleep, the body loses water, which causes the blood viscosity to increase. Drinking some water before going to bed can improve blood viscosity, thereby reducing the risk of cardiovascular and cerebrovascular diseases such as myocardial infarction, cerebral thrombosis, and stroke caused by blood vessel blockage. In addition, in the dry autumn and winter seasons, drinking water before going to bed can also moisturize the respiratory tract, keep breathing unobstructed, and improve sleep quality.

The following types of people are more suitable for drinking water before going to bed.

01Patients with cardiovascular and cerebrovascular diseases

For some patients with cardiovascular and cerebrovascular diseases, if they do not drink water all night and sweat while sleeping, the blood viscosity will increase, which can easily lead to the formation of blood clots and induce cardiovascular and cerebrovascular diseases such as angina pectoris, myocardial infarction, cerebral thrombosis, etc.

Therefore, for people at high risk of cardiovascular and cerebrovascular diseases, drinking some water before going to bed and when getting up at night can dilute the blood concentration and reduce the incidence of cardiovascular and cerebrovascular diseases. It should be noted that for people with poor heart function, drinking too much water before going to bed also has the risk of heart failure, so don't drink too much water before going to bed.

02People with prostate hyperplasia

People with prostate hyperplasia often have frequent urination at night and are more likely to be dehydrated than normal people. They should also drink water before going to bed and replenish water after getting up at night to ensure that the body has just enough water.

03 Elderly people

Elderly people should drink a sip of water before getting up at night, because they have less activity at night, blood flow is slow, and blood is more viscous, which increases the incidence of myocardial infarction, cerebral thrombosis and other diseases. Drinking water in the morning and evening can help reduce blood viscosity and is very helpful in preventing cardiovascular and cerebrovascular diseases.

Tips: For patients with severe renal failure and those undergoing dialysis treatment, drinking a lot of water before going to bed will cause water retention in the body, which may lead to edema and even induce heart failure. Everyone should drink an appropriate amount of water before going to bed according to their own situation.
