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

In this special episode, Chris and Xand are out of the studio and into the woods, exploring something a little different - the connection between nature and our health and wellbeing.

You’ve probably heard claims that just being in green spaces can boost your mood, help you recover from illness, and even lower your stress. But how much of that is really backed by science, and how much is just the latest wellness fad? To do this they are joined by Baroness Kathy Willis, Professor of Biodiversity at Oxford University.
