Lack of sleep could contribute to mental health problems, researchers reveal

Study finds therapy designed to treat insomnia also reduced paranoia and hallucinations, and improved depression and anxiety in patients

Mental health problems including psychotic experiences could in part be down to a lack of sleep, researchers have revealed.

A new study found that people who had undertaken a course of cognitive behavioural therapy (CBT) designed specifically to treat insomnia not only found their sleep improved, but also experienced reduced paranoia and fewer hallucinations - both psychotic experiences - as well as improvements in depression and anxiety.
