Water turns to steam at boiling point, we know that. The steam coming off of the water is made up of volatile compounds. They burn out of the water and turn into gasses, i.e. the water is turning into steam. When you start re-boiling the already cooled down water, the dissolved volatile gasses and minerals are subjected to the same process once again and the chemical components are changing their structure for the second time. This time the process of the second change is actually very harmful.
The moment water is put for re-boiling, the dangerous components that should escape from the water will stay inside. Suddenly, you are interested in knowing more about those harmful substances, am I right? Most common, re-boiled water contains fluoride, nitrates and arsenic. It is known that healthy minerals are retained in boiled water. By re-boiling it the healthy components are creating a dangerous situation to which we are all exposed because they become amassed in the re-boiled water. For instance, calcium salts can cause kidney stones and gallstones if significant amount is consumed, and calcium salt can definitely collect in the re-boiled water.
The negative effects of re-boiled water
By drinking re-boiling water you are exposing yourself to toxic nitrates, arsenic intoxication and excessive fluoride intake.
Whenever the nitrates in water are exposed to high temperatures i.e. when the water reaches the boiling point, they become toxic. The composition of the nitrates will undergo a complete change, in other words, they are turning into nitrosamines which are carcinogenic.
The bottom line is, stop exposing yourself to ‘invisible’ dangerous toxins just because you’ve decided to save a minute of your time by not changing the boiled and already cooled down water in the kettle. Filling the kettle with fresh water takes less than a minute and will keep your body toxin-free. Avoid things that are harmful for your well-being. It’s worth it!
