Episode notes

Your study or at least the one that I saw in cell that was male subjects. Have you given any thoughts as to whether these protocols and I appreciate they just may not be evidence but do you think for any reason the protocol or approach to temperature or duration would be different for a female versus a male? Yeah I'm glad that you asked me this question actually because I just want to reflect on that a bitBecause it's something that people have asked me a lot and some actually get a little bit um yeah they want to discuss at least why I recruited only men for my study.

Episode #250. Ice baths and other forms of cold water exposure have gained a huge amount of traction in the past few years. I’m joined by expert Dr Susanna Søberg to examine what the science says – is cold water exposure safe? What does the research say about the bold health claims? Is brown fat just a buzzword? How do you safely and effectively implement hot and cold exposure into your life? Dr Søberg answers these questions and many more in this three-hour deep dive into cold water immersion.
