The intestinal barrier serves as a gatekeeper to the human body. The loss of the health and integrity of this barrier influences multiple aspects of human health – including cardiometabolic function, neurological health, behavior, and more – in surprising and unexpected ways. One of these ways involves lipopolysaccharide, or LPS, a bacterial product that arises in the intestine, and its interaction with far distal tissues and organs via the induction of immune mediators.

Dr. Rhonda Patrick was the keynote speaker for the Metabolic Health Summit, held May 5 – 8, 2022, in Santa Barbara, California. Her presentation described the role that intestinal permeability and bacterial products play in aging, inflammation, and chronic disease.

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.

In this episode, we'll discuss:

  • 00:00:00 - Introduction
  • 00:02:46 - Summary of sauna benefits
  • 00:10:47 - Heat as an aerobic exercise mimetic
