To heat water in the microwave can be an accessible method of brewing tea or coffee; however, experts from the Food and Drug Administration (FDAfor its acronym in English), warn that doing so exponentially raises the risk of burns.

Why is it dangerous to heat water in the microwave?

According to the chemist and researcher, Deborah García, the microwave heats by radiation, that is, it orients the molecules in a single direction, so the Water it could reach 100 degrees Celsius without obviously boiling. This phenomenon is called “overheating” and may cause burns.

The University of Sydney Faculty of PhysicsAustralia, specifies that overheating is the heating of a liquid at a temperature above its boiling point boiling normal. “It is unstable and can pass very quickly to liquid to the boiling point, generating a substantial amount of steam”, he specifies.

What is the main risk of overheating?

According to the FDAdue to the Water tends to overheat when he gets into the microwave, it does not give the characteristic indications of being boiling. Failing to see these signs, have been reported Burns Severe skin or boiling water injuries to people’s faces and hands as a result of this phenomenon.

“If you use a microwave oven to heat water above the boiling point in a clean container, the slightest disturbance or movement can cause the water to explode violently and jump out of the container.”

How to reduce the risk of microwave heated water?

The FDA itself claims that adding ingredients such as instant coffee or sugar to the water before heating greatly reduces the risk of rash Hot water. Also remember to follow the manufacturer’s instructions when heating water and other substances.

On the other hand, the Australian University recommends not using containers that have no imperfections, for example a cup or a glass of ceramic or glass with little use. It is best to always use containers that have at least a little scratched surface and use non-metallic objects such as wooden spoons.

Finally, according to Deborah García, with objects without imperfections, the bubbles have nowhere to adhere and there is no the boil which, with a vibration, can cause the explosion. Although the main recommendation is never to overheat the water in the microwave or heat it in a pot.
