Do You Re-boil Your Water? Here's Why You Might Want to Stop...

We are all guilty of putting the kettle on to boil water and before we can use it the hot water cools down, and so we re-boil the water again. Most of us re-boil water without wondering is it harmful to our health. Just asking do you reboil your water doesn't sound or seem dangerous. Well, the World Health Organization (WHO) states that “Drinking-water contains the most significant threat to public health and when you boil it chemicals become concentrated, and whatever salts and impurities are now in the water added with nitrates, arsenic, and fluoride is incredibly bad for our health.

The first reaction to finding out that the water is cold is to turn on the kettle to re-boil it, but what you don’t know is the harm it causes when you do that. Most of us think nothing of re-boiling water in the kettle to make morning coffee or tea. However, we should never re-boil water, and unfortunately, it is something that all of us have never heard ‘why not’ in science class.

The reason you should never re-boil your water is that after water is boiled, the composition of water changes and the volatile compounds evaporate, and gasses dissolve making it safe to drink. However, once it cools and you re-boil it, that’s when you expose the water to, dangerous substances that have accumulated instead of being disposed of. You, unknowingly, put yourself at risk of concentrating a variety of unwanted chemicals in the water that is unsafe to drink.

Three Damaging Effects of Re-Boiled Water...

Reason number one, re-boiling water can make it highly toxic, and it contains nitrates, and once it is exposed to high heat, it transforms to nitrosamines, which are carcinogenic. Nitrates are poisonous and have been connected to diseases like ovarian, colon, rectal, leukemia, bladder, stomach, non-Hodgkin lymphoma, oesophageal, pancreatic and thyroid cancer.

The second reason you should never re-boil water, drinking water carries arsenic material which poses the most significant threat to human health. This is exposed to the water and causes health issues like neurological diseases, infertility, cancer, cardiovascular disease, and developmental disorders.

The third reason re-boiling water is harmful is that water contains fluoride. Scientifically it has been proven to be dangerous, but the US government insists on keeping it in the water supply. Therefore, once water is re-boiled fluoride is exposed to the water and causes damaging effects on neurological and cognitive development in children according to data from Harvard University.

Last words, If the water you boiled is entirely pure, distilled, de-ionized water, it is okay to re-boil the water. However, if it is faucet or tap water, it contains dissolved gasses and minerals. Moreover, when tap water is re-boiled, the chemical compounds change and become harmful. The dangerous substances do not dispose of. Instead, it accumulates.

Also, re-boiled water consists of compounds amassed, that are of considerable risk and contain certain chemicals and harmful substances such as fluoride, arsenic, and nitrates. After water is boiled and gets cold even healthy minerals can become detrimental when amassed; calcium salts can lead to gallstones and kidney stones when consumed in enormous quantities.

Is It Safe to Reboil Water? What You Should Know About Reboiled Water

What happen when you boil water?
Reboiling water will do precisely three things:
If you have perfectly pure distilled deionized water, nothing will happen
It kills any germs and bacteria
Some volatile contaminants in the water that survived the first boiling might be driven out by the second boiling
Re-boil faucet or tap water, it contains dissolved gasses and minerals and you risk concentrating certain undesirable chemicals that are harmful to your health
When you boil water, nitrates turn into nitrosamines and become carcinogenic
Some additional evaporation will occur, causing anything dissolved in the water (salts, contaminants) to be slightly more concentrated.
When you re-boil water, it releases minerals that become detrimental when amassed; calcium salts can lead to gallstones and kidney stones when consumed in enormous quantities
When you boil water, it dissolved gases and minerals that have undergone a chemical transformation amass
Some additional material from the surface of the vessel you're boiling the water in might dissolve into the water.
