Frequent sauna bathing can protect men against dementia
The more frequently saunas were taken, the lower was the risk of dementia. Among those taking a sauna 4-7 times a week, the risk of any form of dementia was 66% lower and the risk of Alzheimer’s disease 65% lower than among those taking a sauna just once a week.
