In this “Ask Me Anything” (AMA) episode, Peter and Bob explore the quality of evidence for hot and cold therapy. In the discussion, they evaluate the safety, efficacy, and opportunity costs of various hot and cold therapy protocols, and Peter ultimately considers the addition of dry sauna to his longevity toolkit. Once again, Bob Kaplan, Peter’s head of research, will be asking the questions. If you’re not a subscriber and listening on a podcast player, you’ll only be able to hear a preview of the AMA.
