Benefits of steam sauna

Steam saunas offer several health benefits, primarily in reducing the risk of cardiovascular events and promoting longevity. According to studies discussed by Andrew Huberman, using a steam sauna two to three times per week can reduce the likelihood of cardiovascular events by 27% compared to using it once a week. Further benefits are seen with more frequent use; those using the sauna four to seven times per week were 50% less likely to suffer from such events. This thermal therapy also helps in all-cause mortality reduction, suggesting that regular sauna use notably enhances longevity by lessening the likelihood of various mortal health events 1.

Additionally, Andrew Huberman highlights that deliberate heat exposure increases growth hormone levels when used infrequently (e.g., once a week with multiple short sessions). For cardiovascular gains and better overall health, however, more frequent sessions (about three per week) are recommended, providing heat exposure for 60 minutes spread over these sessions. Heat exposure sessions ideally should be later in the day to aid sleep through natural cooling post-exposure 2.

It's important to be aware of the physical stresses of heat exposure, including intense heart and body responses similar to those experienced during moderate exercise 3. Those with certain health conditions, such as recent heart issues or severe blood pressure problems, should consult their physician before engaging in sauna sessions.
