New research indicates that frequent heat exposure from sauna use throughout the week is associated with a lower risk of dementia and Alzheimer’s disease.
This is according to a unique study by researchers at the University of Eastern Finland (UEF), who’s findings were published in the December 2016 journal Age and Ageing.
The research team studied the participants weekly ‘sauna bathing’ habits, and the participants were divided into three groups: those who took about a 15-minute sauna 4-7 times a week, those using a sauna 2-3 times a week, and those who only used a sauna once a week.
The researchers found a clear connection between the frequency of weekly sauna habits and the risk of dementia. The more frequently participants used a sauna each week, the lower was their risk of dementia. For example, for bathers who used a sauna 4-7 times a week, the risk of any form of dementia was 66 percent lower and the risk of Alzheimer's disease 65 percent lower than among participants who took sauna baths just once a week.
