Get comfortable, let go of the cares of the day and take a sonic journey with Dr Michael Mosley. In this new sound-filled podcast series, designed to help you drift off, each episode focuses on a scientifically-proven sleep technique and takes a deep dive through some incredible sleep-related bodily mechanisms. It’s something that the great teachers of meditation and yoga have known about and used for millennia, but science has only really just caught up with: slowing the breath. Via a tiny cluster of cells in the brain, this simple act can send you into a more relaxing, peaceful state and towards sleep. Guest: Ian Roberston, Emeritus Professor of Psychology at Trinity College, Dublin. Producer, sound design and mixing: Richard Ward Assistant Producer: Gulnar Mimaroglu Editor: Zoe Heron Specially composed music by Richard Atkinson (Mcasso) A BBC Studios production for BBC Radio 4.
