How good is drinking water in summer?

You should drink more water in summer.

The hot sun is in the sky, and the heat is unbearable. People try to wear less clothes, drink ice water, stay indoors, or hide in air-conditioned rooms all day. Some of these methods are very harmful to human health.

When the weather is hot, the heat generated in the human body is not easy to dissipate, and the gastrointestinal temperature will be higher. After drinking soda, soda can take away the heat in the human body and make people feel cool. However, if you suddenly drink a lot of cold soda, your stomach will be stimulated by supercooling, and the muscles and blood vessels in the gastrointestinal tract will contract hard, causing gastrointestinal spasm and stomach pain. At the same time, the sugar content of soft drinks is high, and if you drink too much, your stomach will swell and reduce your stomach's ability to digest food. Therefore, when the weather is hot, don't be greedy for cold and drink more ice water. Ventilation has a cooling effect, but it is easy to cause headache and backache, especially for the elderly and the infirm. Long-term living in an air-conditioned room is not the best choice. Because the temperature changes greatly, people are prone to catch cold when they go in and out. Of course, on a hot day, it is even more inappropriate to drink alcohol and coffee, because alcohol will dilate people's blood vessels and may cause fatal harm to patients with cardiovascular diseases.

The best way to cool off summer heat is to drink plenty of water. Even if you are not thirsty, it is best to drink tea and mineral water. Drinking tea in summer is especially thirst-quenching. Because tea contains a variety of nutrients, it can chemically react with the digestive juice in the mouth, moisten the mouth and eliminate the feeling of thirst. In addition, caffeine and other substances in tea will affect body temperature regulation, accelerate heat dissipation, promote the excretion of waste in the body, and make the whole body feel cool and comfortable.
