If you’re the sort of person who’s conscious of not wasting resources, it’s tempting to fill up the electric kettle once and keep boiling the same water over and over again until it’s empty. Well, you might want to opt instead for just as much fresh water as you need for just that one cup of tea.
But why? It’s just water. Boiling it purifies it, after all. So giving it a second boil should make it all the more sterile, right? Nope, in fact he exact opposite is true.
Let’s take a closer look at what happens when water boils.
At first glance, you see little bubbles and steam, but something else happens at the chemical level. By boiling them several times, the oxygen content changes and hazardous substances begin to accumulate.
One can feel the difference in taste when making tea: the taste of fresh water tea will be quite different than tea with water that were boiled again.
Boiling water is a great way to k.i.l.l bacteria definitely, but when you boil water over and over again, dangerous gases and toxic substances like Arsen, Nitrate and Fluoride can form as a result of changing the chemical structure. Many studies have shown the connection between fluoride and the harmful effect it has on the nervous system and brain.
So after all this, you’re not only drinking water, and the minerals that are actually good for you, like calcium, can cause problems such as kidney stones.
So that’s why you should not boil water twice. Of course, the damage is caused when the water is consumed in large quantities.
A small amount is unlikely to cause serious problems, but you may want to give the remaining water in the kettle to your plants instead – it is not harmful to them at all.
So you should definitely be careful and know the consequences when you boil the same water regularly.
