In the scorching summer sun, many people sweat profusely even if they are inactive, and in this case, many people blindly drink cold water or cold drinks, believing that it is the most enjoyable and the most thirst-quenching thing. In fact, when people sweat a lot and feel very thirsty, they will drink cold water or cold drinks desperately, and the result will only be more and more thirsty as they drink, resulting in reflex sweating, which makes the body lose more water, which is very harmful to physical health. Heavy sweating can also lead to a lack of salt in the body, causing heat cramps that can be life-threatening.
The correct way to do this is to develop the habit of drinking warm boiled water, and try to drink less or no cold water or cold drinks. According to the research of scientists, the measurement of the two volunteers who drank warm and cold drinks in a hot climate with an infrared temperature recorder showed that warm drinks can reduce the temperature by 1 2, while cold drinks can only make the mouth colder.
At the same time, the self-perception of the two groups was different, and the warm drinkers felt cool and comfortable, and their thirst was completely eliminated. Those who drink cold are not well-organized, and the thirst comes again. Warm water molecules similar to body temperature can enter the intestinal wall relatively quickly and neatly, so they can quench thirst. In addition, drinking warm drinks to sweat a little can take away part of the body heat, so drinking water is harmless to the body.
On the contrary, cold drinks absorb a lot of heat from the mouth and stomach, and the internal organs are suddenly cold, which will affect the digestive function at least and cause stomach cramps and diarrhea at worst. Therefore, it is better to drink warm in midsummer.

In the hot summer, people always feel thirsty and want to quench their thirst. And when it comes to drinking water, people always have the question: should they drink hot water or ice water? This issue has been controversial, so let's take a look at it.
First of all, drinking hot water can reduce the feeling of thirst to a certain extent. Because when hot water enters the human body, it will activate the nerves of the gastrointestinal tract and promote gastrointestinal peristalsis, so that people can feel that there is water moving in the stomach, resulting in a sense of satiety and satisfaction, and reducing thirst. In addition, drinking hot water can also promote blood circulation, increase metabolism and detoxification effects.
However, for the hot summer months, ice water is more popular to drink. Because ice water can quickly lower the temperature of the mouth and throat, reducing thirst and sore throat. In addition, drinking ice water can also lower body temperature, make people feel more comfortable, and can also relieve the discomfort of hot weather.
In general, both hot and cold water have their own advantages and disadvantages. If you are in a dry environment and when you are very thirsty, drinking hot water can reduce the feeling of thirst and promote gastrointestinal motility, but if it is a hot summer, drinking ice water can lower the temperature of your mouth and throat more quickly, relieving thirst and the discomfort of heat.
Of course, it is also important to note that drinking ice or hot water too often may have some effect on the body. Therefore, when choosing a way to drink water, we need to comprehensively consider our actual situation and environment, and choose a suitable way to drink water. At the same time, we also need to master the correct drinking water method to ensure the hygiene and safety of drinking water.
