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.

Deliberately tensing and then relaxing groups of muscles all through the body is a potent technique for engaging your body’s relaxation response. We also encounter the magnificently named Golgi tendon organ afferent nerve cells, and the interconnected nodes of the brain.

Guest: Ian Robertson, professor at Trinity College Dublin.
