I would like to know what harms drinking water that has been heated can cause to the human body
Thread Content
I want to heat drinking water to make it warm for washing hands and other purposes. What are the potential harms to the human body from drinking such water?
After drinking water is heated, its taste might improve a bit, and the potential hazards should be reduced. Also, find out what type of water you’re drinking – purified water or mineral water.
After drinking water is heated, its taste might improve a bit, but the potential hazards should be reduced. Also, consider what type of water you are drinking – purified water or mineral water. If the water contains certain minerals, heating can cause changes in the valence of those ions or lead to the formation of precipitates, thereby reducing their effectiveness.

I’m so confused by what the original poster said. What harm could drinking water possibly have? It’s meant for drinking after all
We just drink hot water – are the dangers of heating clearly explained?
Drinking water should be able to be heated, right? Don’t many people do that?
Do you mean the drinking water supplied by the water company through pipes? Short-term heating is harmless.
Since water dispensers heat water repeatedly, they can cause nitrite ions to be present in the water, and this substance is a carcinogen that is certainly harmful to the human body. Therefore, it is advised not to rely on water dispensers constantly
Reheating water repeatedly can produce the carcinogenic substance nitrites, but the question is: \"If water is heated to make it warm enough for washing hands, what are the risks to health from drinking such water?\" ”I don’t understand what it means. The temperature of the hand wash water shouldn’t be that high; there should be no problem with this kind of heating, right?
I’ve been drinking it for a long time now, and it seems like no problems have arisen.
That makes sense, but I wonder if anyone has measured the exact amount? Bottled water is usually disinfected with ozone; could ozone cause nitrite ions to form in the water without it being heated?
Everyone has their own preferences; there are great individual differences among people. Chinese traditions also differ from those abroad, and there is no such thing as right or wrong. It’s just a form of adaptation.
How are nitrites formed? Don’t understand
It’s best not to drink water that has been heated over and over again; it’s fine to use it for washing hands if that’s all you intend to do! I’m just curious, why heat water for washing hands using drinking water? ! Can’t it be washed directly with tap water? !
Heating drinking water to a temperature suitable for washing hands, around 50–60 degrees Celsius, poses no harm to human consumption. It’s the same principle as boiling tap water and then cooling it to 50–60 degrees Celsius before drinking it. If the drinking water is pure water, with even lower ion content, there are still no issues
Heating drinking water to wash hands has the drawback of reducing the body’s adaptability. It’s fine to wash hands directly with drinking water, and it’s even better to do so after heating the water. What harm is there in that? It’s too extravagant; it harms the mental health of the general public.
If drinking water is reheated repeatedly and stored for too long, it’s always a bit concerning to drink it. Water at dozens of degrees is more likely to breed bacteria, right?
