It may seem obvious that a lack of sleep can exacerbate poor mental health - whether a symptom, cause or both, the two go hand in hand. But until very recently, there was little scientific research to back this idea up – and as a result, sleep treatments have been overlooked as a potential remedy for poor mental health. Prof Daniel Freeman is a clinical psychologist who's trying to change that. He's leading studies into the effectiveness of sleep treatments for people experiencing psychosis and getting positive results.

In this episode, Alisha speaks to Prof Freeman about the importance of sleep, its potential in fighting the global mental health crisis, and some of the surprisingly simple techniques that can aid a better night's rest. They hear from Ryan, who saw a dramatic shift in his mental health after taking part in one of Prof Freeman's studies.
