Water is indeed the source of life, a healthy adult, the body water occupies about 70% of body weight! Our daily intake of water, not only to meet the body’s needs, while the excess water is also involved in the body’s metabolism, urine production is inseparable from water, metabolic waste will be excreted with urine, so more hot water is really good for the body.
Many people’s definition of hot water, is just after boiling water, that only boiling water can promote blood circulation, so that the body sweats a lot. But I do not know, in the oral cavity, esophagus and the surface of the stomach, are covered with very soft mucous membrane, their ability to accept temperature is very limited, in general, the temperature of the mucous membrane is mostly maintained at about 36.5 to 37.2 ℃;.
And the most acceptable temperature limit of the mucous membrane, is only 60 ℃! Therefore, from a scientific point of view, the most suitable eating temperature is between 10~40℃. If a large number of eating temperature exceeds 60 ℃ or more, the delicate mucous membrane will be food burns!
However, the good thing is that the mucous membrane is surrounded by rich blood vessels and the blood circulation is relatively good. So, even if the mucosal tissue is injured, it can be quickly shed, proliferate and repair, so eating hot food once in a while will not affect the organism too much!
But, for people who often eat hot food and drink hot water, the situation can be very bad!
The mucosa will wander back and forth in damage and repair under constant thermal stimulation, and the mucosa keeps growing and thickening, and its own response to thermal stimulation will gradually decrease, leaving hot food lovers in a vicious circle. Moreover, the nerve reflexes of the esophageal mucosa are relatively sluggish, and often there is no pain signal even when it is injured.
So the brain will mistakenly think: the mucosa is very healthy, let the heat come more violently!
However, the mucosa will gradually develop inflammation in the day to day damage, which includes esophagitis, chronic gastritis, etc. In addition to the mucous membrane, the gums also have a great opinion of hot water, the food is too hot gums will easily be scalded, over time, easy to cause gum ulcers, dentin allergy, thus forming allergic toothache;.
Moreover, the most terrible thing is that in the process of injury-proliferation-repair of mucous membrane, cell division will gradually produce some bad molecules, that is, cells with abnormal morphology and DNA structure, and when these cells reach a certain number and are not recognized by the immune system, “cancer” may appear and take root in the body.
Whether the cancer occurs in the esophagus or stomach, it is often difficult to be detected by patients in the early stage, or even without any abnormality. Many patients only go to the hospital for examination when they have symptoms such as pain and difficulty in swallowing, and are finally diagnosed as cancerous! Who would have thought that it was just because of their love for hot food that they left the opportunity for cancer to take advantage of at the beginning?
Therefore, it is not accurate to say “drink more hot water”, rather, we should drink more warm water, when the water is cooled to below 40℃, it is the most suitable temperature for drinking. In addition, we should also avoid eating hot pot, hot and spicy hot, noodles, so as not to cause mucosal burns.
