Is cognitive behavioral therapy effective at treating sleep disorders?

To some degree: It depends on the type of sleep disorder you are talking about. If it is part of sleep apnea, bipolar disorder or psychotic disorders where paranoia, hallucinations, racing thoughts and fear keep people awake it is of limited value. In anxiety disorders, obsessive compulsive disorders or situational disorders it very well may help. Sometimes with depression and sleep issues it can be helpful also.

Absolutely: Cognitive behavioral therapy for insomnia (cbt-i) is a wonderful method for treating insomnia without (or with) medications. Techniques used include: stimulus control, sleep hygiene, sleep restriction, relaxation training and cognitive therapy.

CBTI: Studies have shown cbti has more efficacy than medications for chronic insomnia.

CBT for Insomnia: It is considered the gold standard for chronic insomnia. Not an overnight fix, but you probably didn't develop it overnight. I teach a 4 week class with workbooks, sleep diaries, and a ton of great information about how to do one at a time experiments on behavior or environment to find solutions!
