MANY of us think nothing of re-boiling water in the kettle to make our morning cuppa, but it turns out doing so exposes us to some serious health risks according to health experts.
Most tap waters contain natural chemical compounds, the make-up of which changes when first boiled. This is a good thing as it kills any germs and bacteria present in the water.
However, when it is re-heated, the dissolved gases and minerals that have undergone a chemical transformation amass and become significantly more toxic.
Julie Harrison from Improve Your Health said:
“The chemicals in the water get concentrated, things like nitrates, arsenic and fluoride.”
“Every time you reboil the water, they get more concentrated, and you really don’t want to be having them in your body.”
Nitrates turn into nitrosamines and become carcinogenic. These chemicals have been linked to diseases like leukemia and non-Hodgkin lymphoma as well as various types of cancer. Meanwhile arsenic accumulates which can result in cancer, heart disease, infertility and neurological problems.
Minerals that are good for us in small doses, such as calcium salts, can be very harmful when re-boiled and can lead to kidney stones and gallstones.
Worryingly, an increase in the level of fluoride can have damaging effects on the cognitive and neurological development of children. Harrison also recommends using filtered water and only as you need it, to avoid the water sitting in the plastic for any length of time.
