How much water should you drink a day? What are the benefits of drinking water?

Water is the source of life. People drink water every day, and the body's normal metabolism is inseparable from water. But do you know how much water you should drink in a day? Today, I will talk about this issue specifically for you, and also let you know the benefits of drinking water.

How much water should you drink in a day?

Under normal circumstances, it is best for healthy people to drink eight glasses of water a day. This number comes from the recommendation of the American Food and Nutrition Association in 1945. In 2007, world nutritionists such as Carroll and Velleman also publicly stated that healthy people need to drink at least six to eight glasses of water a day.

What are the benefits of drinking water?

1. Lose weight

Normally, when people are on an empty stomach, drinking more warm water can dilute the gastric juice in the stomach, and can satisfy the stomach's need for food and reduce the body's food intake. In addition, water can also participate in the burning and metabolism of fat in the human body and can reduce the accumulation of fat in the human body. Therefore, drinking water has a certain weight-loss effect.

2. Protect your heart

If people drink more water on a regular basis, they can protect their hearts and reduce the incidence of heart disease, because most warm water is rich in magnesium ions, which can directly act on the human heart, improve heart function, and prevent stroke. Scientists have long discovered that people who drink more than eight cups of water a day have a lower incidence of cardiovascular and cerebrovascular diseases.

3. Prevent and relieve bad breath

The water content in human cells decreases with age. It is said that when people are in their 20s, the water content of their cells is as high as 42%, but when they are in their 70s, the water content of their cells will drop to 35%. At this time, the body's metabolism will slow down, and waste in the body cannot be discharged in time, so people are prone to bad breath. If you can ensure that you drink more water, you can speed up your body's metabolism, promote the discharge of these wastes, and relieve the symptoms in people's mouths.
