There are similar studies showing that regular saunas lower cardiovascular risk and dementia risk up to 63% (a summary here http://outcomereference.com/causes/108 http://outcomereference.com/causes/108 ) Like the hot bath study, these were limited to very specific populations (Finnish). I have yet to see studies of hot bath or saunas on different ethnicities or different locations. At the end of the day though, nothing beats regular moderate exercise. It's the only lifestyle that has no side-effects, cheap, accessible to everyone anywhere, and with demonstrated short-term and long-term effects. Walk, run 5k, hike, bike to work, your heart and your family will be grateful!
