Navigating Cold Exposure for Raynaud's Syndrome

This chapter examines the impacts of deliberate cold exposure on Raynaud's syndrome, sharing personal anecdotes and the need for more scientific research in this area. It provides practical tips for coping with cold environments and highlights the physiological responses to cold immersion. The discussion also addresses safety considerations during cold water swimming, especially for vulnerable populations.

Episode notes

In this episode, my guest is Susanna Søberg, PhD. She earned her doctoral degree at the University of Copenhagen in Denmark, researching the effects of deliberate cold and deliberate heat exposure on metabolism and other aspects of human physiology. We discuss how cold or sauna can improve metabolism, cardiovascular and brain health, balance hormones, and decrease inflammation. Dr. Søberg discusses how deliberate cold protocols can improve glucose metabolism and insulin sensitivity and trigger release of neurotransmitters like dopamine and norepinephrine which enhance energy, mood, and focus. We compare cold showers and cold immersion, traditional and infrared saunas, and other variables. This episode provides actionable tools and answers to common questions about the use of deliberate cold and heat to improve health.
