Have the health effects of sauna use been studied scientifically?
The Finns have always known that going to the sauna is good for you. Because of this, it is perhaps understandable that not much actual scientific research has been carried out in Finland on the benefits of sauna use. Why bother researching something that is obvious!
However, these types of studies have been carried out elsewhere in the world, and Finland has also turned up the heat in science in recent years in particular. In other words, we now have an even better understanding of the effects of sauna use and why these effects are positive.
