Boiling water can kill bacteria and remove substances harmful to the human body, because tap water is chlorinated, and chlorine interacts with residual organic matter in the water to form toxic carcinogenic compounds such as halogenated hydrocarbons and chloroform. When the water temperature reaches 90, the content of halogenated hydrocarbons rises to 191 micrograms, and chloroform rises to 177 micrograms, both exceeding the national standard by 2 times. When the water temperature reached 100, the levels of halogenated hydrocarbons and chloroform were 110 micrograms and 99 micrograms per liter, respectively. If you continue to boil for 3 minutes, the two substances quickly drop to micrograms and micrograms per liter, respectively, to meet the drinking standard. Therefore, it is best to boil water for about 3 minutes.
In order to save water, some people often reheat the leftover boiled water, which is a bad habit. Because repeated boiling of water will cause the aging of water, it will not only cause the loss of minerals that are beneficial to the human body, but also may produce some harmful substances such as nitrite. Once nitrite enters the human body in large quantities, it can make the red blood cells in the blood lose the function of carrying oxygen, resulting in tissue hypoxia, people will drink this water for a long time will cause nausea, vomiting, headache, nails and lips purple, palpitation and other symptoms, serious can also cause hypoxia, and may even induce cancer.
After getting up in the morning, drink a cup of cold and white, which is good for health. Many people like to dry a glass of boiling water the night before and drink it again the next morning. This is okay when the temperature is not high; For example, in summer, when the temperature exceeds 30 degrees Celsius, the air humidity is high, and the bacteria multiply quickly, the cold boiled water overnight will lose its biological activity, and it is very easy to be contaminated and cause diarrhea.
You can pour half a small cup of boiled water the night before, then cover the lid, and mix the boiling water with warm water the next morning.
In addition, the time of cooling and boiling should not be too long, and the boiling water boiled on the same day is best drunk on the same day. It is best not to drink it again if it is left cool for more than 3 days.
