Are children allowed to use the sauna?

KLAFS FAQ for well-being

Children have just as many sweat glands per square centimetre of skin as adults, so they can react to heat just as adequately. The only essential difference between children and adults is the surface area of their skin. Their heads and torsos are larger in proportion to their arms and legs, which mean they absorb and emit heat faster – particularly as they also generally have a thinner layer of fat. Children of all ages – including babies – may use the sauna. And they tend to love the experience! But they should always be accompanied by an adult, and they should never stay inside the sauna for too long.
