Why are most saunas decorated with wood?

Sauna rooms are generally made of wood. These woods have been degreased at high temperature and have no peculiar smell. Pine wood is soft, with medium and high density, slow heat conduction and heat preservation.

If you use metal materials, water vapor will increase its oxidation and corrosion, and plastic products will emit odor. Using wood is an environmentally friendly and safe choice. The traditional Finnish sauna is an all-wood structure. There are three levels of wooden couch built against the wall of the sauna room. The temperature of each level is different.

This is also the reason why we feel that the temperature of our water is higher when we wash our hands in winter. The specific heat capacity of metal is small, and the specific heat capacity of wood is large. If the sauna room is heated, then the wood heating is also slower.
