But I believe many people have heard that westerners never drink hot water, even adding two pieces of ice does not affect their health. Almost only people in China can drink hot water, so can drinking hot water really keep you healthy?
Drinking hot water has a long history in China. As early as Huangdi Neijing, it was recorded that "treating diseases as soup" and other ancient books "drinking soup in winter and drinking water in summer", among which "soup" refers to hot water. In traditional medicine, drinking hot water is also a way to warm the stomach. Drinking cold water makes people feel easy to have diarrhea.
In fact, drinking boiled water was originally advocated because boiled hot water can reduce microbial pollution. After the outbreak of cholera in western countries, in order to ensure the cleanliness of drinking water, a pipeline water supply system was built, but at that time, China did not have the conditions to build a direct drinking water system, so it advocated drinking boiled hot water.
In addition, because the water quality is too hard, many areas burn hot water. After boiling, it can reduce some calcium and magnesium ions in water and improve the taste. In this way, everyone's stomach is more suitable for warm water, and some people with weak spleen and stomach will suddenly feel uncomfortable when drinking cold water. Westerners are used to drinking cold water, and it is no problem to drink cold water all day.
Moreover, the statement that foreigners don't drink hot water is actually biased, because foreigners will drink hot soup when eating, as well as some hot coffee and hot cocoa. When it is cold, they don't drink hot drinks at all. But for drinking hot water to treat colds, most of them belong to psychological comfort. Because light colds are generally within the range of people's immune ability, most cold medicines only relieve uncomfortable symptoms and can't cure the problem, so even if they don't take medicine, they will heal themselves in a week or so.
In a word, our body is more adaptable to hot water, so drinking hot water will be more comfortable, but it generally plays a psychological comfort role in relieving discomfort. The temperature of hot water is not as hot as possible. According to the International Agency for Research on Cancer, drinking hot drinks above 65℃ frequently may increase the risk of esophageal cancer. The World Health Organization also lists hot drinks above 65℃ as Class 2A carcinogens. Simply put, it is a substance that is easy to cause cancer, and it belongs to the same category as malaria and heavy metal lead. If you want to drink hot water, 40 to 50℃ is the most suitable.
