Two types of water that are really dangerous for the body

There are many myths associated with water. Sometimes it is difficult to understand whether water is always good for the body and which types of water are dangerous.
There is an opinion that water boiled several times is so dangerous that it causes cancer. But is this true? In fact, despite the fact that chlorine may remain in the water due to repeated boiling, there is not enough scientific data to confirm its danger to humans. Moreover, chlorine is used to disinfect water.
At the same time, repeated boiling can indeed contribute to the fact that nitrates in water turn into dangerous nitrites. But the point here is in the dose of these substances. Therefore, it is also not a fact that you will develop cancer if you drink such water.
As for water left overnight, you can still drink it. Although experts do not recommend doing so. According to some scientific data, if you boil water for half an hour, the amount of nitrites in it remains stable and does not change much overnight.
At the same time, there are two types of water that are really harmful to health.
Mixed water. Such water is obtained by mixing boiled and raw water. The fact is that even when mixing raw water with boiling water, the temperature will not be sufficient to destroy all dangerous bacteria. With prolonged use of such water, a person may develop intestinal infectious diseases.
Very hot water. That is, water whose temperature is above 65 degrees Celsius. According to representatives of the International Agency for Research on Cancer, the use of such water increases the likelihood of developing esophageal cancer. The human esophagus normally tolerates only drinks whose temperature is a maximum of 40-50 degrees.
