About Dr. Sarah Novak

I’m Dr. Sarah Novak — integrative medicine practitioner, researcher, and someone who became genuinely convinced that infrared sauna therapy has a meaningful place in modern wellness practice.

My background is in internal medicine with postdoctoral work in environmental health. I became interested in thermal therapy through research on cardiovascular adaptations to heat stress — and the more I dug into the literature, the more impressed I was.

I created HeatDepth to share evidence-based information about infrared saunas — what they do, what they don’t do, and how to use them safely and effectively.

My Approach

I apply the same evidence standards to sauna claims that I apply to any clinical intervention. Strong claims require strong evidence. When the research is preliminary, I say so. When something is well-established, I say that too.
