Sleep hygiene isn't enough (and here's why that's good news)

If you've struggled with sleep for any length of time, you've probably been handed the same list: cool dark room, no screens, no caffeine after noon, go to bed at the same time every night. That list is called sleep hygiene, and it's a reasonable starting point. Unfortunately, for most people with chronic insomnia it's not enough.

Why sleep hygiene alone falls short

Sleep hygiene is mostly a list of things not to do. For someone whose sleep is basically fine, avoiding caffeine late and keeping a consistent bedtime can make the difference between good nights and great ones. For someone with chronic insomnia, the problem usually isn't habits, it's that the brain has learned to associate the bed with being awake, and long stretches in bed have weakened the body's natural sleep pressure.

Tightening hygiene doesn't unwind those associations. You can do everything "right" and still lie awake.

What actually moves the needle

CBT-I addresses the two things sleep hygiene can't reach: the learned association between bed and wakefulness, and the scattered sleep schedule that has weakened your sleep pressure. Resolving both is what turns chronic insomnia back into restful sleep.

Why that's good news

It means the problem isn't a character flaw or a sign you need to try harder. There's a specific, well-studied treatment that works — and you haven't tried it yet.
