This episode features a discussion with MedCram co-founder Kyle Allred on the effects of sauna. I had the pleasure of being interviewed by Kyle on all things sauna science and we're posting that discussion for you here. As an exercise mimetic, sauna use has anti-inflammatory, mood-elevating, and detoxifying properties that research increasingly shows may deliver cardiovascular and brain benefits.

The science of sauna use has been a research interest of mine for many years and this discussion is by far one of the most well-rounded discussions I've had on the subject. Thanks to Kyle and MedCram for having me for his interview.
