Most of us avoid the cold. We crank up the heating, bundle up in layers, and curse every icy gust of wind. But what if freezing — or even sweating — could be the key to better health?

In this episode, Jonathan is joined by two world-leading scientists to explore a radical idea: that extreme temperatures might unlock powerful benefits for your metabolism, mental health, and even longevity.

Dr. Susanna Søberg is a Danish metabolic scientist and founder of the Søberg Institute. She discovered the Søberg Principle. Her findings? Just minutes of exposure a few times a week could improve insulin sensitivity, activate brown fat, and lower stress.

She’s joined by Prof. Tim Spector - professor of genetic epidemiology at King’s College London, one of the world’s top 100 most cited scientists, and scientific co-founder at ZOE - who explains how these temperature shocks may even impact your gut microbiome.

This episode will change how you think about discomfort, explain the science behind extreme temperatures and might just inspire your healthiest new habit.
