The reason why room temperature is said is mainly for some particularly hot water (including drinks and soup). Drinking too hot water for a long time will increase the risk of esophageal cancer, such as kungfu tea. However, most people don't need to worry too much about hot water. Drinking water with an average temperature of 30-40 degrees is no problem. You think it is better to drink hot water in the future. The same is true of ice water, as long as it is hygienic, it is not a big problem. Everyone's living habits are different, as long as you don't feel uncomfortable drinking. It is incorrect to say that people who drink ice water are unhealthy. In fact, many people have the habit of drinking ice water, and there is nothing unhealthy.
Generally speaking, as long as it is not particularly hot water, hot water, warm water and ice water are neither healthy nor very healthy. Just choose your favorite temperature, regardless of what others drink.
Of course, occasionally people will drink ice water, cardia tear and myocardial infarction. But I noticed that these people have an extreme situation when drinking ice water. For example, after exercise and a lot of physical labor, patients drink a lot of ice water in one breath. Although these extreme cases are rare, I suggest that it is safer to drink ice water here.
As for hot water. Just don't drink hot water. People who like and want to drink can still drink. No problem. However, it should be noted that drinking hot drinks above 65℃ for a long time may increase the risk of esophageal cancer. Too hot diet for a long time will burn the esophageal mucosa repeatedly, causing repeated repair and proliferation of local mucosa and forming chronic inflammation. Over time, it will lead to pathological changes of esophageal mucosa. Different people have different perceptions of hot and cold. People who are used to drinking hot water for a long time may not feel that the water they drink is too hot.
In order to avoid this situation, it is recommended that you drink "warm water" instead of "hot water". Simply put, it is to ensure that the inlet water temperature is lower than the oral temperature. This can effectively avoid the risk of scalding the esophageal mucosa by drinking water.
