Strengthens the immune system
Medical research shows that regular use of saunas and steam baths strengthens the immune system. It is the body's reaction to the high temperature that pushes the immune system and gives it extra strength. We get a fever when we get sick, so increased body temperature is our self-defense against viruses and bacteria. By raising the body temperature, viruses and bacteria find it more difficult to survive.
Therefore, it is not illogical that increased body temperature with the help of saunas and steam baths can support the body's self-defense against diseases. The body can benefit from sweating, because the sweat cleanses the skin of insidious bacteria that can otherwise stress the immune system, by flushing bacteria-removing sweat out of the pores.
Scientific research has shown that sauna bathing increases the number of white blood cells and other factors in the blood that are important for the immune system. An article in the European Journal of Epidemiology shows that regular sauna bathing leads to a reduced incidence of colds and flu.
