Studies have been done looking at people that go into a relatively hot sauna, so this would be a 163 ºF sauna, if they stay in for 30 minutes, they can raise their heat shock proteins about 50% over their baseline levels. And heat shock proteins have a lot of beneficial effects. So, they're involved with preventing proteins from aggregating and forming plaques in the brain and the vascular system. They also are very important for preventing muscle atrophy.
