Why is it that the more you drink cold water when you are thirsty, the more thirsty you will be?

In hot summer, people will sweat a lot even if they are not active. In this case, many people blindly drink cold water or cold drinks, thinking that this is the most pleasant and thirst-quenching. In fact, when people sweat a lot and feel thirsty, they will only drink cold water or cold drinks more and more, which will lead to reflective sweating, which will lead to more water loss in the body and is very harmful to health.

Excessive sweating can also lead to salt deficiency in the body, leading to heat spasm and life-threatening. The correct way is to form the habit of drinking warm water, and try to drink less or no cold water or cold drinks. According to the research of scientists, the skin of two volunteers who drank warm drinks and cold drinks was measured by infrared temperature recorder in hot climate. The results show that warm drinks can reduce the skin temperature 1℃~ 2℃, while cold drinks can only cool the mouth.

At the same time, the self-feeling of the two groups is different. People who drink warm drinks feel cool and comfortable, and their thirst disappears completely. People who use cold drinks will feel weak and thirsty again. Warm water molecules close to body temperature can enter the intestinal wall neatly and quickly, so they can quench their thirst. In addition, drinking warm water can take away some heat in the body, so drinking water is harmless to the body. On the contrary, cold drinks will absorb a lot of heat from the mouth and stomach, and the internal organs will suddenly become cold, which will affect the digestive function and even cause stomach cramps and diarrhea in midsummer.

It is cold in winter, so drinking cold water directly will cause irritation to internal organs. Hot water quenches thirst faster than cold water or ice water. After hot boiled water enters the body, it can quickly penetrate into cells, so that the dehydrated body can be replenished with water in time.
