Does it make sense to “avoid cold drinks when the weather is hot”?

It's the beginning of autumn, is the hot summer about to pass? In fact, the autumn heat is well-deserved, so the coolness you think may not be that fast. In this summer, have you ever been entangled in whether to drink ice water and eat cold drinks? After all, there are "good advice" everywhere to discourage ice water and cold drinks. Even your mother often tells you to drink more hot water and eat less cold drinks and ice water. Especially girls, they are often discouraged... Why is ice water described as a scourge by everyone?

So is it true that ice water cannot be drunk? Let’s talk about it today.

01. Good advice on ice water

"People pour 0℃ water into a 37℃ stomach, but the urine is hot. The human body temperature is 37℃. Who converts 0℃ ice water into 37℃ urine? It is the spleen and stomach. The spleen and stomach can't stand it after drinking it, so they transfer the essence (vital energy) from the kidneys into heat energy to boil it to 37℃. In the long run, your kidneys will be weakened. Drinking ice water, ice beer and beverages all the time will definitely cause kidney deficiency, affect memory, and increase the risk of bone necrosis. In order to nourish the kidneys and nourish the yang energy! Warm reminder: It's hot, so stop drinking ice drinks."

I believe that such words have appeared a lot in your circle of friends, especially now that we are still in the hot season, but ice water is really cool, especially when you are walking on the street under the scorching sun in summer, a glass of ice water is so comfortable, but every time I think of this passage, I have to discourage myself.

02. Is ice water really a terrible thing?

This ice is commonly known as kidney essence ice. Of course, the above jokes are also deceptions of some WeChat joke makers. Why do we say that? Let's start with the temperature homeostasis of the human body.

The normal body temperature of a person is about 36.8, and this temperature is maintained in balance by the body's energy metabolism, which is a very precise regulation of the human body.

Take breathing as an example: an adult breathes more than 20,000 times a day, inhaling about 20 kilograms of air, which is more than 10 times the food and water intake in a day. And air is not easy to control. How can our air be exactly 36.8? Especially our temperature changes throughout the year, so the air will be adjusted to this temperature when it enters the body, and it is the same when it is exhaled.

But why don't the jokesters say that we need to breathe constant temperature air? This is more frequent and more necessary than drinking water. If this is true, then people's vitality will be exhausted.

In addition, our diet is also not accurate to 36.8, which is also ignored by the joke maker. The same is true for the environment we come into contact with, such as beds and chairs.

Therefore, moderation is very important. After all, "talking about toxicity without considering the dosage is just hooliganism." However, one thing to remind you is that too much is as bad as too little. The human body has a limited tolerance. Don't consume cold food too quickly or in excess.

Eating too cold food can easily cause too large a local temperature difference, leading to discomfort, such as gastrointestinal cramps and pain; consuming too much cold food can cause an imbalance in the body's temperature homeostasis.

So, ice water is not a terrible thing, but it must be used in moderation.
