The International Agency for Research on Cancer (IARC), which is affiliated with the World Health Organization, has ruled hot drinks above 65°C as carcinogenic.
This news has caused hot water panic among the public, but in fact the truth is not so simple.
As we all know, the human body is in a certain range under the role of temperature regulation mechanism, when the temperature is higher or lower than the range represents the generation of disease, but also means that there is a limit to the temperature tolerance of the human body.
Studies have found that the tolerance temperature of the oral mucosa and gastrointestinal mucosa to food in the human body is 30-40 degrees Celsius, and some people may reach 50 degrees Celsius.
And when the human body ingests hot drinks, the temperature of the esophagus will rise 6-12 degrees Celsius for a short time, and the danger is that once it exceeds 65 degrees Celsius, the oral and gastrointestinal mucosa may be damaged.
Although hot beverages are the most popular, what is emphasized in this view is actually the temperature, which means that long-term intake of hot water above 65 degrees Celsius may indeed contribute to the risk of esophageal cancer.
In addition, hot beverages such as coffee and tea drinks that contain irritating factors can also cause inflammation and irritation after damaging the gastrointestinal mucosa at high temperatures, thus increasing the risk of cancer, which is also a factor to consider.
The range of hot water is actually very wide, 100degrees Celsius is hot,20-30 degrees Celsius is also hot, but can drink hot water generally refers to 30-50 degrees Celsius, and is boiled to reduce the temperature of the formation of low-temperature water, if the boiling water to drink and cool white water to drink, there is generally no problem.
If the ordinary warm water and raw water to drink, it may cause diarrhea, abdominal pain and other symptoms, the reason is that raw water may contain microorganisms, harmful substances, coupled with the role of hot water, may produce stimulation and damage to the stomach and intestines.
Hot water can bring some benefits to the human body, but it is not a panacea, the efficacy is limited, at most can play some relief effect, and no treatment effect of disease.
Generally speaking, often drink hot drinks can increase the body's ability to fight viruses, drink hot drinks, water vapor will also enter the mouth, moisten the upper respiratory tract, promote blood circulation, enhance the ability of white blood cells to, virus phagocytosis, to prevent the invasion of germs.
For women, the body is prone to cold, drinking hot drinks can warm the stomach, drive away the cold, with the role of conservation of human stomach gas, hot drinks into the body, can warm various organs, so that the whole body feels relaxed and comfortable.
But can not be long-term intake of hot water with too high a temperature, as long as the water is clean and hygienic, it will not harm health. Prefer to drink cold water or hot water mainly related to their dietary habits.
There is also no argument that people who drink hot water regularly are necessarily healthier than those who drink cold water regularly.
