Sauna, not just for relaxation

Traditionally, Finnish saunas raise the ambient temperature by heating wood-panelled rooms by burning wood fires. Today, most modern saunas are heated by electric heaters, allowing the indoor temperature to be better controlled within the optimal range of 80-90°C. In recent years, there have also been some saunas that use far-infrared heaters. The operating temperature is usually around 45 to 60°C, and the body can be heated directly by thermal radiation.

In addition, the thermal effect of the high temperature environment of the sauna will activate a series of proteins called "Heat Shock Proteins" (HSPs). HSP proteins are involved in various immune functions, cell signaling, cell cycle A family of regulated proteins, they can protect and repair damaged proteins in cells to prevent protein disorder or accumulation in the body, thereby protecting the normal metabolism of cells, including muscle cells. By activating the heat shock response generated by HSP, it can also increase Increase the number of mitochondria, improve mitochondrial function, and help improve the body's oxidative metabolism. The activity of some HSP proteins, such as HSP70, is also related to anti-cancer and longevity.

Are you a wood burner or an electric one? This is the biggest debate in the sauna world. The heat source for the sauna is obviously a key part, as traditional designs use wood-burning stoves. Electric heaters are cheaper and require less maintenance, but many believe it's like grilling steak on charcoal versus gas. It's a matter of taste. Just know that if you do tend to burn wood, you'll have to acquire wood to burn, be able to tend it while the fire burns, and probably forgo the indoor sauna, lest your homeowner's insurance skyrocket.
