You should immediately stop re-boiling water if you have a kettle like this

Every day we come across different opinions on how to properly handle drinking water.

Some argue that boiling water several times makes it completely safe to drink, while others insist that repeated boiling can change its composition, making it less healthy and even slightly toxic.

Research conducted by Chinese scientists has shown that boiling water once does not necessarily destroy all the bacteria and microorganisms remaining in it. Some of them can survive and even reproduce after boiling again. However, it should be noted that if the water is initially clean and meets sanitary standards, then the number of boils does not play a big role.

From a safety perspective, it is important to consider the possible risks when re-boiling water. For example, experts have discovered that heating water in plastic kettles can release formaldehyde, which is a potentially hazardous substance. Experiments have shown that in some cases the formaldehyde content increases after each subsequent boiling, Roskachestvo reports.

Having said that, it is recommended to boil water only once before drinking to minimize risks and ensure safety. If there is water left after use, it is recommended to pour it out and add fresh water before the next boil. This is a precautionary measure that will help avoid possible water quality problems and maintain health.
