why?
Think boiling water is easy?
In fact, there is a lot of knowledge. When ordinary people boil water, they are used to turning off the heat immediately after the water is boiled, but they don't know that this will leave the chloride in the water, which is harmful to health. Some experts pointed out that after the water is boiled, the lid should be opened and boiled for one to two minutes, so as to effectively volatilize the chloride in the water, otherwise it will have an adverse effect on the internal organs, joints and bones of the human body.
When we boil water, the chemistry is change.
Which usually a good thing as it boils out volatile compounds and dissolves gasses. However If water is reboiled again the chemical compounds change for the worst and you are actually concentrating many harmful chemicals instead of getting rid of them.
In many places, drinking tap water needs to be chlorinated in order to be disinfected and sterilized. It is not known that water treated with chlorine will separate two carcinogens: "halogenated hydrocarbons" and "chloroform". Accumulation in the body may affect kidney function and body Joints and bone cheese, the most common is low back pain, severely affects the bone marrow.
When we boil the water, the water temperature reaches 100°C. These carcinogens will be greatly reduced as the water evaporates. Therefore, it is recommended that you do not turn off the fire immediately after the water is boiled. You should open the lid and boil for one to two minutes, or when the water is about to Open the lid when boiling, let the water boil and wait one to two minutes before turning off the fire, so that the chlorides and residual harmful substances in the water can volatilize through the steam.
According to "Daily Health", a research survey found that changing the water temperature will affect the sweating response of participants. Drinking water at 16°C can make people drink more water and sweat less, so they are dehydrated athletes. The best temperature for drinking water.
Some office buildings or families implement the principle of no waste. You can’t finish drinking the water today, and you can re-boil it again tomorrow. Sometimes you just add new water and boil it together. This repeated boiling of water can lead to Harmful substances such as "nitrite" have increased. Toxic "nitrite" can also cause hypoxia in the brain. In severe cases, it may cause coma or even death. In medicine, "nitrite" will produce chemical reactions in the human body to form "nitroso compounds", which are carcinogenic to animals. Therefore, for the sake of the body, it is better to drink less overnight tea.
