There’s a chill in the air as the winter months come around again. But the cold isn’t always something to fight or guard against. With a little bit of care, you can invite the cold into your life - with real benefits for health and mood. In each episode of this new podcast series, Dr Michael Mosley uncovers the science behind a different way you can harness the power of the cold, alongside the very latest research and atmospheric sound design.

In this episode, Michael goes for a jog on a chilly day, and finds out how exercising in colder weather can allow you to go further than on a hot day, enabling you to work harder, for longer, with less effort.
