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.

What is it about the natural world that has such a positive impact upon our physiology - slowing our heart rate and blood pressure, settling our thoughts and so much more? One theory is that it’s connected to the repeating patterns in nature - fractals - and Michael discovers that we live in a fractal universe.

Guest: Richard Taylor, professor at the University of Oregon.
