Welcome to What’s Up Docs?, the podcast where doctors and identical twins Chris and Xand van Tulleken cut through the confusion around every aspect of our health and wellbeing.

In this episode, Chris and Xand will shine a light on…light. They discuss why the sun can help lift our mood, and its effects on our sleep and general wellbeing. Joining them to discuss this is Professor Hester Parr, a professor of Human Geography with an interest in sunlight's effect on mental health and runs the research group Living with Seasonal Affective Disorder.
