Treating insomnia may reduce mental health problems

Treating insomnia with online cognitive behavioural therapy (CBT) could reduce mental health problems such as anxiety, depression, and paranoia, according to research. The study found that sleep disruption is a driving factor in the occurrence of paranoia, hallucinatory experiences, and other mental health problems in young adults with an average age of 25. The research in The Lancet Psychiatry was led by the University of Oxford with Lancaster University and others. Professor Steven Jones from the Spectrum Centre for Mental Health Research at Lancaster University said: "This very large trial indicates how a digital intervention can improve not only sleep but in doing so can alleviate a range of mental health symptoms including depression, anxiety and psychotic symptoms in University students." The researchers aimed to improve sleep in these individuals in order to determine the effect on mental health problems such as paranoia (excessive mistrust), anxiety, and depression. 3,755 university students across the UK were randomised into two groups. One group received online cognitive behaviour therapy (CBT) for insomnia; the other group did not but had access to standard treatments. This is thought to be the largest ever randomised controlled trial of a psychological treatment for mental health and the first study large enough to determine the effects of treating insomnia on psychotic experiences.
