Making hospitals less stressful

Hospitals can make you sicker. It's a strange thought for places that also can make you healthier. But think about the constant noise, the distinctive hospital smell, the bright lights.There's lots of evidence that most patients find hospitals themselves very stressful. This stress can lead to slower healing times or even a higher chance of being readmitted to hospital.This week, we look at some interesting work happening around the world to try to improve the hospital environment.We hear from people who are using nature to heal, are redesigning lighting systems and are blocking out the noise. And by learning what stresses humans out, we can learn a lot about how our bodies recover and heal. Presenter: Myra Anubi Reporter/producer: Charlotte Pritchard
