warmth on the skin: how much is too much?

A toasted Skin syndrome can be avoided quite easily: by not so often exposed to the intense warmth. But how much is too much?

This question is not so easy to answer. According to dermatologist Wagner, a few evenings with a hot water bottle do not lead to chronic hitel anose. However, there is still not enough knowledge about what role the genetic predisposition plays. Or after how many hours of heat a discoloration arises.

Especially people who often fall asleep with hot water bottle or often have a heat patch on their back should therefore check the skin regularly.

triggered heat anose of any kind of deeper and long -lasting warmth, says Wagner. A hot water bottle, heating blanket, seat heating in the car - and of course a hot laptop on the lap. Even if we usually find their heat as pleasant, too often the skin should not be exposed to it.

No phenomenon of current time

The toasted-Skin syndrome is not even a phenomenon of the home office or the increased heating costs. Heatemelanosis was particularly common among forging, train leaders or people who worked on stoves or open fire, says Wagner. In her practice, dermatologist Esther Wißmüller meets the toasted Skin syndrome "every now and then". She suspects that the phenomenon "certainly occurs more often".

As tempting as it may be to snuggle into bed with a heating blanket on the sofa or with a hot water bottle - it is better not to do that every evening, recommends dermatologist Wagner. Especially in small children who cannot communicate if it gets too warm for them, you should be very careful at temperatures from 40 degrees. (dpa/tmn)
