CBT-I works. Almost nobody gets it. Here's the math.

The first-line treatment almost nobody sees

Every guideline on chronic insomnia says the same thing. CBT-I (cognitive behavioral therapy for insomnia) is the first-line treatment. Better than sleeping pills. Better than sleep hygiene advice. The American College of Physicians 2016 guideline spells it out: CBT-I before drugs, always. That's been the recommendation for over a decade.

And only a small fraction of people with chronic insomnia ever receive it. Koffel, Bramoweth and Ulmer's 2018 review of CBT-I access and utilization lays out the mismatch: the treatment works, the guidelines endorse it, and the supply of trained providers isn't close to the demand. That's the access gap in a nutshell. The best treatment we have is almost completely unavailable.

Why the gap is so big

CBT-I requires a trained clinician. The pool of board-certified behavioral sleep medicine specialists in the US numbers in the low hundreds, against maybe 30 million adults with chronic insomnia. Even if every clinician worked 80 hours a week seeing only insomnia patients, the math still doesn't work.

Digital CBT-I programs exist and have decent evidence, but completion rates are low. The standard protocol is 6 to 8 weeks of homework, sleep diaries, and behavioral restriction. Behavioral restriction is the part where you deliberately sleep-deprive yourself to rebuild sleep pressure, and most people quit before it starts working.

So you've got a treatment that works, is evidence-based, and has almost zero availability. The alternatives are sleeping pills (which have their own problems), sleep hygiene advice (which doesn't help chronic cases), and nothing.

Where hypnotherapy fits

Hypnotherapy isn't a replacement for CBT-I. Different mechanism, different target. But it's available, it's cheap, it doesn't require a 6-week commitment, and the evidence for it in sleep is actually decent. For the 99% of people who won't get CBT-I, it's worth a real look.

The thing nobody says out loud in sleep medicine: the treatment you can actually access beats the treatment you theoretically should have gotten.
