It is not known through what mechanisms sauna may generate health benefits. Sauna is a type of hormetic thermotherapy. Exposure to high heat generates heat shock proteins, which induce mitochondrial biogenesis and have been linked to the regeneration of synapses. It also induces the creation of endorphins, which may reduce pain, and improves circulation.
A 2015 study found that frequent sauna usage lowered men's risk of fatal cardiovascular disease and premature death from other causes. The study's conclusion reports, "Increased frequency of sauna bathing is associated with a reduced risk of SCD, CHD, CVD, and all-cause mortality. Further studies are warranted to establish the potential mechanism that links sauna bathing and cardiovascular health."
