According to researchers at the University of Eastern Finland, sauna visits and improvement in memory diseases tied after following more than 2,300 middle-aged Finnish men for more than 20 years.
According to the study, people who went to the sauna four to seven times a week were found 66 percent less likely to be diagnosed with dementia, and 65 percent less likely with Alzheimer 's disease, than those taking a sauna once a week.
Jari Laukkanen, senior researcher and a professor of clinical medicine at the University of Eastern Finland said, "We have taken into account other lifestyle factors, like physical activity and socioeconomic factors ... There is an independent effect of sauna on these outcomes."
He further said that the study only indicated an association between the sauna and memory diseases, and the findings would have to be fleshed out through further studies with different age groups, other nationalities and women.
"After sauna , you may have lower blood pressure, and blood pressure is an important risk factor in cardiovascular and memory diseases. This may be one possible explanation for our findings," Laukkanen said.
Club members go to the sauna several times a week, and in winter cool off with a swim in the icy Baltic Sea.
