Drink more hot water? Drinking water correctly is a technical job

"Drink more hot water" is a simple and caring expression, but now it has become a popular online meme to tease boys. Water is the source of life, and 70% of the human body is water. It can be said that drinking more water is often the right thing to do.

Water is essential for the maintenance of life. Water is responsible for transporting various oxygen, nutrients, enzymes, hormones and immune cells in our body. It also helps us excrete toxins and metabolites, enhance gastrointestinal digestion and absorption, regulate body temperature and lubricate joints.

In addition, water can regulate blood concentration, help normal blood circulation, maintain skin elasticity, reduce the formation of pigmentation, and promote fat metabolism. Therefore, if you want to beautify your skin and lose weight, you must drink more water.

For ordinary people, drinking water is a low-cost way to stay healthy.

Instead of spending a lot of money and going through a lot of trouble to buy various health products and paying the IQ tax, it is better to drink more boiled water, which is cheap and healthy.

Although we need to drink water every day, you may not always know how to drink water.

If you don't believe it, let's take a look. First of all, "drink more hot water" does not mean "drink more scalding water". Drinking water that is too hot can cause burns to the oral mucosa. Research results show that drinking overheated beverages (temperature above 65°C) may cause esophageal cancer.

The hot soy milk that you drink hurriedly in the morning, the hot tea that veteran cadres love the most, the hot wolfberry tea in the thermos, etc., every sip you drink is burning your esophagus.

So, how much water is enough per day?

We often hear people say "drink eight glasses of water a day", but some people use large sports cups, while others use small coffee cups. So, even if the same eight glasses are consumed, the amount of water consumed is very different. So, how much water is eight glasses of water?

According to the dietary guidelines of the Chinese Nutrition Society, men are recommended to drink more than 1700 ml of water per day, and women are recommended to drink 1500 ml, which is about the amount of three bottles of ordinary mineral water.

Drinking water does not require a fixed schedule. When the body is dehydrated, it will automatically send out signals to remind us to drink water. Thirst and yellow urine are the most typical signs of dehydration. At this time, we should pay attention to replenishing water.

However, drinking too much water is not recommended. Drinking too much water will increase the burden on the heart and kidneys, and even cause water poisoning.

If you are seriously dehydrated, drinking a lot of water in a short period of time may cause hyponatremia. A safe amount of water to drink is within 700 ml per hour, or about 400 ml each time.

When it comes to how to drink water safely, some people will come up with some unknown drinking experience such as "don't drink overnight water" and "don't drink repeatedly boiled water". In fact, the same eight hours interval,

These friends don't dare to drink the water that is left from 11 pm to 7 am the next morning, but they often drink the water from 7 am to 3 pm, saying it's "really delicious."

It can be seen that the saying of overnight water has no basis.

The nitrite content in the water after multiple boiling is still far below the national standard for drinking water, so there is no need to worry about safety issues such as "poisoning" and "cancer".

In fact, as long as you drink the right amount and at the right temperature, you can get 99 points for drinking water!
