Trust Me, I'm a Doctor

As the sun comes out (or not!) the doctors are back doing science research on our behalf. While we prepare to bare our bodies on the beach, Dr Saleyha Ahsan and the University of Oxford test whether it is really possible to bust belly fat, and skin surgeon Gabriel Weston takes a special camera on the streets to see how protective sun cream actually is. Dr Chris van Tulleken tests how cheap a pair of sunglasses we can buy and still be assured protection from damaging UV light. And as the warmer weather tempts more of us to do some exercise, GP Zoe Williams makes a guest appearance to test what it's really doing for our health, whilst Michael Mosley investigates some surprising ways to get the benefits of exercise without doing any at all.

A special programme dedicated to mental health, with experts answering questions surrounding the impact that lack of sleep, stress and laughter can have on our mental wellbeing. Michael Mosley runs a big experiment to find out the best way to beat stress, from gardening to yoga, while Dr Zoe Williams finds out why laughing can be as good as exercise for improving moods. Elsewhere, Dr Alain Gregoire tests how lack of sleep affects our mental health, Surgeon Gabriel Weston investigates the radical new treatment that could cure schizophrenia, and Giles Yeo asks if you can eat your way to happiness.
