In addition, minerals and other trace elements that are beneficial to the human body originally contained in the water are precipitated into scale due to high temperature. The scale contains heavy metal substances harmful to human body, such AS CD, Al, PB, As and HG. Most of these heavy metal ions can accumulate in human body, which will easily lead to cancer lesions for a long time.
A survey by the World Health Organization shows that 80% of diseases and 50% of cancers are related to water pollution.
When drinking water, it is the shortest way to get minerals and trace elements beneficial to human body from water. What is more harmful, serious and influential to human body is that with the increase of temperature, chlorine gas generates several times of chloroform in water. Drinking boiling water for a long time is not good for your health (there is accumulation of toxins). This is the reason why cold water can't water flowers and fish can't live. People are just "a big fish"
At the same time, drinking boiled water often means giving up the source of trace elements needed by the human body. People who drink tap water and boiled water for a long time will accumulate and precipitate harmful substances such as residual chlorine, rust and nitrite in the human body, which will easily lead to constipation, diabetes and other chronic diseases and blood diseases in middle-aged and elderly people. Especially the residual chlorine in tap water can cause breast cancer. Diseases such as rectal cancer and bladder cancer.
When the boiled water is cool enough for people to drink, its molecular cluster is bigger than before, and its activity is lower. Trace elements change from activity to death, and calcium ions in the water become calcium carbonate and sink to the bottom of the water during heating, becoming dead water. They can't find boiled water in foreign countries, so they only drink raw water.
Extended data
Boiled water, also known as cold boiled water and frozen boiled water, is the most consumed water in daily life. It is light and tasteless and extremely common, but it has a very important conditioning effect on the physiological mechanism of the human body.
Drinking a cup of warm boiled water on an empty stomach in the morning is beneficial to the body. For middle-aged and elderly people, it can not only dilute blood, reduce blood viscosity, promote blood circulation, but also reduce the risk of thrombosis and prevent the occurrence of cardiovascular and cerebrovascular diseases at the peak of heart disease. For young people, it can quench thirst and induce diuresis due to the decrease of water in the body after sleeping at night, and it can also make the skin smooth and tender.
