Researchers in Finland have identified a link between regular sauna use and reduced risk of Alzheimer’s disease and other dementias in men.
The authors of the study which you can read in full here concluded:
“In this male population, moderate to high frequency of sauna bathing was associated with lowered risks of dementia and Alzheimer’s disease. Further studies are warranted to establish the potential mechanisms linking sauna bathing and memory diseases”
The researchers speculate that sauna use increases heart rate in a way that is comparable to exercise, which benefits heart health. This same mechanism could also be beneficial for memory, the team suggest.
Compared with men who used a sauna once a week, men who used a sauna four to seven times weekly were found to be at 66 percent lower risk of any dementia and had a 65 percent lower risk of developing Alzheimer’s disease.
