A new prescription: Kathy Willis on how nature can improve your health

Seeing, smelling and being in nature can directly improve your physical and mental health. We may know this intuitively but it is now also backed up by an emerging body of scientific  research. What are the benefits of a walk in the woods? Why does the scent from certain trees enhance cancer-fighting cells in the immune system? What does birdsong have to do with pain management? And what exactly are your houseplants doing for your microbiome?

Alok Jha, The Economist’s science and technology editor, speaks to Kathy Willis, professor of biodiversity at the University of Oxford and author of “Good Nature: The New Science of How Nature Improves Our Health”.
