The medical programme this week devotes itself to the subject of mental health.
Host Michael Mosley conducts an experiment to look at the various ways that we could beat stress and which of them is most effective. Giles Yeo meanwhile wonders if your happiness can be made better by what we eat.
Also Dr. Zoe Williams examines whether laughter can improve your mood as much as exercise, Dr. Alain Gregoire looks at what a lack of sleep does to our mental health and Gabriel Weston deals with a possible cure for schizophrenia.
Trust Me, I’m a Doctor is on BBC Two at 21.00.
