1. It is suitable for cardiovascular patients, diabetics and the elderly to drink water before going to bed

One of the causes of cardiovascular disease is high blood viscosity. Drinking water at night can reduce blood viscosity in patients with cardiovascular disease and alleviate the condition. For diabetics, drinking an appropriate amount of water at night is helpful to maintain blood sugar balance.

The functions of the elderly are somewhat different from those of the young, such as decreased kidney function and sensory function, which may cause the elderly to be unaware of their lack of water. In addition, sweating, breathing, urinating, etc. during sleep at night will reduce the water content in the body and increase the blood viscosity in the body, which may cause blood flow to be blocked, leading to sudden dangers such as myocardial infarction, angina pectoris, and cerebral thrombosis. Therefore, drinking water at night can dilute the blood viscosity in the body and prevent cardiovascular diseases in the elderly.

2. People with prostate problems, heart disease, and poor kidney function are not suitable for drinking water before going to bed.

People with prostate problems who drink water before going to bed will suffer from frequent urination, and frequent waking up at night is not conducive to sleep quality. In order to ensure the sleep quality of this group of people, they should not drink water before going to bed.

For heart patients or people with poor heart function, drinking water before bed will increase the workload of the heart, making the heart more "busy" and there is a risk of causing heart failure, so it is not suitable for such people to drink water before bed.

People with poor kidney function cannot regulate the water in their body as well as normal people. Drinking too much water at night may cause edema and heart failure. Therefore, people with prostate problems, heart patients, and people with poor kidney function are not suitable for drinking water before going to bed.

3. Ordinary people can drink an appropriate amount of water before going to bed

According to a study, an adult consumes about 500 ml of water during sleep at night, while an adult needs about 2000 ml to 3000 ml of water a day. The water loss in the body during sleep at night, plus the water loss after dinner, will increase the blood viscosity in the body if the body does not replenish water, which may lead to a series of diseases. Therefore, it is good for ordinary people to drink appropriate amount of water before going to bed.

Will drinking water before going to bed cause edema the next day?

Generally speaking, there are two types of edema: localized edema and systemic edema. Systemic edema is a type of edema that occurs throughout the body. There are many reasons for this condition. People with poor heart, kidney, and liver function, as well as malnourished people, may suffer from edema. Localized edema only occurs in a certain part of the body, and its causes are also diverse, such as local inflammation, varicose veins in the lower limbs, and so on.

The swelling of the face and eyes when ordinary people wake up in the morning may be caused by poor sleep at night or excessive drinking before going to bed. Of course, when our own ability to drain water decreases, it is also easy to cause edema. Therefore, we should drink a moderate amount of water before going to bed according to our own situation. However, for people with poor kidney function, drinking water before going to bed will cause too much water in the body, which is extremely dangerous and may not only cause edema, but also cause more serious consequences.

How to drink water healthily in daily life?

Water is the source of life. Drinking water properly is good for our health. How to drink water properly? We need to pay attention to details such as drinking time, drinking amount, and drinking method.

1. Drinking time

Research shows that there are three best times to drink water, namely before going to bed, after going to bed, and before meals. Drinking water half an hour before going to bed, after getting up in the morning, and one hour before meals is most helpful to the body. Drinking water before going to bed is to store water for sleeping at night. Drinking water after getting up in the morning can better replenish the water lost at night. One hour before meals, there is not too much food in our stomach. Drinking water at this time will not put too much burden on the liver and kidneys, and it can promote digestion and increase appetite.

2. Water intake

According to the "Dietary Guidelines for Chinese Residents (2022)", under mild climate conditions, adult men with low physical activity levels should drink 1700 ml of water per day, and adult women should drink 1500 ml of water per day to maintain the water needed by our bodies. However, the water we need in our bodies does not refer to various beverages, but ordinary boiled water. Therefore, in life we ​​should drink more boiled water, drink less or no sugary drinks, and also supplement water by eating vegetables, fruits, etc.

3. Drinking water method

There are two ways to drink water: fish drinking and cow drinking. Fish drinking means drinking water in small sips, while cow drinking means drinking water in large gulps. In daily life, we should drink water more in the fish drinking way, because this way of drinking water will not bring more burden to the kidneys and liver, and is conducive to the body's absorption of water. Because of this, this way of drinking water is also very suitable for patients with cardiovascular diseases. People with constipation are more suitable for cow drinking , because cow drinking can stimulate intestinal peristalsis, thereby improving constipation to a certain extent. However, when we are very thirsty, we should not drink water in a cow drinking way, as this may cause us to be choked by water.

In daily life, drinking water that is too hot or too cold is not good for our health. Drinking water that is too hot will irritate the throat, and drinking water that is too cold is not good for the stomach. Water at 18℃ ~ 45℃ is most suitable for us to drink .
