What harm does it do to drink cold water on an empty stomach in the morning? What harm does it do to drink cold water on an empty stomach in the morning?

Water is a very important substance for us human beings, and drinking water is also one of the essential drinks in our daily life. Drinking a cup of warm water on an empty stomach after getting up every morning can not only replenish the water needed by the body in time, but also help to regulate constipation. However, some friends say that it is good to drink cold water on an empty stomach in the morning, but this statement is wrong. Drinking cold water on an empty stomach in the morning is harmful to your health. So what are the dangers of drinking cold water on an empty stomach in the morning? What harm does it do to drink cold water on an empty stomach in the morning?

Myth: It is harmful to get up early and drink cold boiled water on an empty stomach.

"Anyone who gets up early and has the habit of drinking cold water on an empty stomach basically has symptoms of chest tightness, heavy breathing, palpitation, pallor, memory loss and lack of energy. Most women who drink cold drinks in the early days have black menstruation and are prone to menopausal symptoms or long spots on their faces in advance. "

In "Being cheated for 20 years, getting up early and drinking cold water on an empty stomach"! In the article, the "expert" who claimed to have been practicing medicine for 20 years put forward many incredible views: early drinking cold water is not only "women are prone to cold in the palace", but also "almost no heart patients who have the habit of drinking water on an empty stomach in the early days can be cured." "Thirst in the morning is unbearable, which is mostly caused by kidney deficiency. At this time, drinking cold water is more likely to make people weak. "

This runs counter to the traditional idea that "a glass of water in the morning helps to clear the intestines, detoxify and refresh the mind". Although many people know that many absolute statements in this article are not credible, the harm of such a serious degree will still make people feel that it is good to avoid it and would rather believe it! How to drink this water, at that time also confused.

Expert: Drinking cold water for a long time first hurts the spleen and stomach.

"These statements are too unreliable." Feng Chonglian, director of the Chinese Medicine Department of the Third Affiliated Hospital of Guangzhou Medical College, said that Chinese medicine practitioners who don't drink water will cause palace cold and affect fertility. Especially for the problem of uterine cold that women are concerned about, after drinking water into the human body, it must pass through the digestive tract, reach the spleen, stomach and kidney, and then be sent to the whole body through blood, without going straight to the uterus. Even cold water "heated" by human body temperature will warm the water. How can you say that the palace is cold?

Besides, drinking cold water can't cure heart disease. Drinking cold water in the morning will make you feel chest tightness and tightness. The causes of these diseases are often very complicated, not only because of drinking water, but also because of your own physique and living habits. This absolute statement is still not credible.

However, it is really not recommended to get up early and drink cold water or frozen water. Long-term drinking is easy to damage the spleen and stomach, leading to physical decline. The human body is 70% composed of water, which is an important substance to maintain the normal operation and metabolism of the human body. It is most suitable to drink warm boiled water close to body temperature, which can best meet the natural needs of human body. But there is no need to ask that the water you drink is 37 degrees Celsius, which is too picky. Of course, drinking cold water at room temperature will not harm your health, so there is no need to panic.

How to drink water is healthy?

Drink water only when you are thirsty! A glass of water in the morning is unnecessary.

"A glass of water in the morning to clear the intestines and detoxify, refresh the mind" has been recognized as a way of keeping in good health. However, Feng Chonglian said that a glass of water in the morning is not necessary. First of all, drinking water has no detoxification effect, and there is no so-called function of accelerating metabolism. At most, it helps to promote urination and discharge "waste" in time.

The human body is the most sophisticated "instrument". When the body is short of water, it will naturally stimulate the nerves to have a thirst reaction. This is the body reminding you: it's time to drink water! Drink water only when you are thirsty. This is the most correct way to drink water. There is no such thing as "the best drinking time".

Many people feel thirsty in the morning because some water will evaporate when they sleep at night. They haven't urinated all night, so they need to replenish water after getting up early to urinate. This is a normal physiological reaction.

Drink eight glasses of water a day? Food also contains water.

"Eight glasses of water a day" has almost been recognized as the "truth" concept of health preservation. However, experts do not agree with this. There is no absolute amount of water to drink every day. However, drinking water is closely related to urination, and how much water to drink in a day can be calculated by the amount of urination.

Normal people's daily urine output is 65,438+0,500 ml-2,000 ml. With the evaporation of water such as breathing and sweating, the human body excretes about 2,000 ml of water every day (workers who exercise vigorously and sweat heavily excrete more water). This means that the daily intake of water is about 2000 ml, which is the legendary eight glasses of water (250 ml a cup). However, besides drinking water, we also consume water in our daily food. Rice, vegetables, meat and fruits all contain a lot of water, which should also be included in the daily water intake. Therefore, there is no need to be smart enough to force yourself to drink eight glasses of water every day.

The more you drink, the better you drink. Too much water will lead to "water poisoning"

On the basis of the understanding that "drinking water can help to detoxify and maintain beauty", many women desperately drink water every day in order to make their skin more "moist". But is it a problem to drink too much water? The answer is yes.

Drinking too much water can also lead to "water poisoning". The maximum continuous urination speed of human kidney is 16 ml/min. Once the water intake speed is too fast, the excess water will expand the cells and cause "water poisoning". Water poisoning can lead to dizziness, fatigue, vomiting, edema and other symptoms, which may be fatal in extreme cases. Of course, the amount of drinking water to achieve water poisoning is very large, which is difficult to achieve under normal circumstances. Studies have shown that even people who sweat as much as 4000 ml a day, people who drink a lot of water every day will not suffer from water poisoning. Therefore, there is no need to panic too much.

A2。 Physiological saline close to human physiological concentration is really more suitable for human needs, and drinking proper physiological saline will not affect health.
