Sit back, leave behind the cares of the day and take a sonic journey with Dr Michael Mosley. In this new podcast series, designed to help you let go and unwind, each episode focuses on a scientifically-proven technique for activating the body’s built-in relaxation response, and takes a deep dive to explore what’s happening inside as we find stillness and calm.

Most of us instinctively know that music can have a huge impact on our mood. But it can also be an effective tool to tap into your body’s relaxation response. Plus thought loops, soundwaves and an encounter with the Organ of Corti.

Guest: Stefan Koelsch, professor at the University of Bergen in Norway.
