Because boiling water contains a certain amount of nitrite, if it is boiled repeatedly, the nitrite in the water will increase. Nitrite is a strong blood poison, which can oxidize the divalent iron in hemoglobin into trivalent iron after entering the human body in large quantities, so that the blood loses its oxygen-carrying function, resulting in hypoxic suffocation in the human body. Another dangerous potential toxicity of nitrite is that it can be combined with amines in the stomach to form nitrosamines, which are strong carcinogens.
Therefore, the water boiled for the second time should not be drunk.
There is also electron radiation and continuous heat emitting. For example, mobile phones, energy-intensive radiators.
It doesn't hurt and it's convenient.
