This #saunahealth benefit came up during last Sunday's morning sauna, from someone who had heard @foundmyfitness on the @timferriss podcast talking about how sauna use promotes longevity!
- A study published in JAMA journal of internal medicine in 2015 found that frequent sauna use decreased death rates in participants, and the hotter/longer/more frequent, the better. The study looked at 2000 Finnish men (why isn't that a surprise?) over a period of 20 years. 49% of those who sauna once a week died during the observation period, compared to 38% that used sauna 2-3 times a week, and 31% that had sauna 4+ times per week. I'd love to see a study comparing once a week users to non-users. - One major reason for increased longevity is the heart health benefits of sauna. Heart disease is the leading cause of death in NZ, and sauna has been found to help wth blood pressure, cholesterol, and overall heart health.
- There are some fancy studies and theories about sauna increasing Heat Shock Protein levels and FOX03 expression. These mechanisms do a bunch of cool stuff, including fighting off deformed proteins that contribute to neurodegenerative diseases. - I'm no doctor, but that fact that most saunas are full of old people seems like a good sign.
