If you want trustworthy information on insomnia and CBT-I, the best starting points are the NHS, NICE and The Sleep Charity — all free, evidence-based and written for the public. This page brings together reliable UK resources on sleep and its treatment, alongside a note on Dr Kushnir’s own published work, so you can read further from sources you can rely on.
There is a great deal of sleep advice online, and much of it is superficial or simply wrong. The resources below are reputable, evidence-based and a sound foundation for understanding insomnia and how it is treated.
Trusted UK resources
NHS — Insomnia
Clear, practical guidance on the symptoms, causes and treatment of insomnia, including when to see a GP.
NICE
The National Institute for Health and Care Excellence sets the clinical guidance behind NHS care, including the recommendation of CBT-I as the first-line treatment for chronic insomnia.
The Sleep Charity
A UK charity offering free information, support and resources on sleep for adults and children.
American Academy of Sleep Medicine (AASM)
A leading professional body whose guidelines, alongside NICE, recommend CBT-I as first-line treatment for chronic insomnia.
Books by Dr Kushnir
Dr Jonathan Kushnir has authored 17 books on sleep and anxiety, drawing on more than 25 academic publications and many years of clinical work. His book on the cognitive behavioural approach to insomnia (CBT-I) sets out, in plain language, how the sleep system works and how to identify and change the patterns that keep insomnia going — moving well beyond quick tips towards a genuine, practical understanding.
This title is currently available in Hebrew, so it will be of most use to Hebrew-speaking readers. For everyone else, the NHS, NICE and The Sleep Charity resources above are excellent free starting points in English.
