Digital cognitive behavioral therapy (dCBT), an efficacious treatment for chronic insomnia, also improved daytime functional health, psychological well-being, and sleep-related quality of life, reported a study in JAMA Psychiatry. The findings suggest that mental health and well-being improve when insomnia is successfully treated.

The 1711 participants with self-reported symptoms of insomnia were randomly assigned to dCBT for 12 weeks (six 20-minute web and/or mobile sessions) or to online sleep hygiene education (SHE).
