In the list of carcinogens published by the World Health Organization's International Agency for Research on Cancer, " drinking hot drinks above 65°C may increase the risk of esophageal cancer " is listed as a 2A carcinogen (probably carcinogenic).

When people eat, if the temperature is too high, it will cause a certain degree of burns to the oral cavity and esophageal mucosa . The burned surface of the esophageal mucosa will fall off and be renewed in time. Repeated heat damage will accelerate the rate of cell proliferation and cause mutations, which may lead to cell cancer.

So don’t drink hot water!

First, it burns your mouth; second, it may cause cancer.

When should you drink water?

For most people, by the time they feel thirsty, the water in their bodies has already been lost (1%-2%), so we advocate that you should actively drink water even when you don’t feel thirsty .

You can also observe your own urination. If the amount of urine is small and the color is dark yellow , this reminds you that it is time to drink some water.

For some people who drink less water for a long time, their sense of thirst will become lower, in other words, they are less likely to feel thirsty, which leads to less water drinking. Therefore, drinking water should be done in small amounts and multiple times to develop a habit.
