Benefits of using boiled water instead of normal water are known and understood by everyone. But, just like all other processes, boiling water also has some disadvantages.


Each time you boil water, its components do a reverse which makes it unhealthy for consumption. Frequently boiling water increases the amount of arsenic, nitrite and fluoride in it, and this can harm your health.

In addition to this, the vapour produced by boiling water has a tendency to re-enter the vessel, which can be a cause of serious ailments.
Here is some more detail on how boiling water over and over makes it unsuitable for your health.

Toxic nitrite

Boiling of water exposes nitrite, which is one of its components. However, re-boiling water transforms nitrite into a toxin. High temperature turns nitrite into nitrosamine, which can cause fatal cancers.

Arsenic intoxication

When water is boiled multiple times, the amount of arsenic in it increases disastrously. Consumption of this water puts you at risk of fatal conditions such as cancer, heart attack, several mental conditions and even infertility. People who consume arsenic polluted water in excess or for many years can experience skin damage or develop problems with their circulatory system.
