“Why do you even need wood impregnation in a steam room?” - some lover of steaming will definitely exclaim. And we agree with him that this question is quite controversial, and therefore everyone answers it himself the way he likes best.
What makes it so controversial? Oddly enough, but the wish for health for yourself, your household and everyone who comes to your steam room. When you know that there is no “chemistry” waiting inside you, the relationship immediately becomes trusting. But the big question is what exactly is considered a harmful chemical . If it is, say, beeswax, is it harmful or not? What about linseed oil? This means you can add it to food.
