Stimulus control therapy retrains the association between your bed and sleep. You go to bed only when sleepy, get up when you cannot sleep, hold one fixed wake time, and skip naps. The American Academy of Sleep Medicine suggests it can treat chronic insomnia on its own — which sleep hygiene advice cannot.
Six rules: the four Richard Bootzin published in the 1970s, and two added later. The set below is the version described in the 2025 standard-definitions paper, and the wording of the original four is close to his.
Rule three is the one people negotiate with, and it is the one carrying the treatment. Bootzin left the timing deliberately vague — "if you find yourself unable to sleep, get up" — and over the years that hardened into what clinicians now call the 15-minute rule.
It works by conditioning. Your bed is a cue, and cues get their meaning from what reliably follows them. If most nights you get into bed and sleep arrives, the bed becomes a sleep cue and you start feeling drowsy while you brush your teeth. If most nights you get into bed and then lie there running through tomorrow, the bed becomes a cue for alertness — and it works just as reliably in that direction.
That is why the instruction is to leave. Every hour you spend awake and frustrated in bed is a training session, and it is training the wrong thing. Getting up is not giving in; it is refusing to practise.
It is the convention that if you are still awake after about 15 minutes, you get up. It is a useful rule of thumb, and it is not in the original instructions. That matters, because the number invites the exact behaviour the method is trying to stop.
Do not time it. Clock-watching in the dark is its own arousal machine, and a phone screen at 2 a.m. adds light to the problem. The workable version is the feeling rather than the number: if you have gone from lying-there to lying-there-annoyed, that is your 15 minutes.
Because one of them can carry a course of treatment on its own and the other cannot, and the guideline is explicit about it. The AASM's 2021 review suggests stimulus control can be used on its own to treat chronic insomnia in adults. In the same document, it suggests clinicians not use sleep hygiene as the whole treatment.
Those two sentences sit a few lines apart in one guideline, and the difference is not about effort. A cool dark room and a caffeine cutoff are sensible, and they do not change what your bed means to your brain. If you have already fixed your sleep hygiene and still cannot sleep, that is not a failure of discipline — you were doing the one thing the guideline suggests clinicians not use on its own.
Stimulus control is also where the advice you may have read about getting out of bed when you cannot sleep comes from. It is not folk wisdom. It is one component of CBT-I with its own evidence base.
Then you change the instruction instead of dropping it. The 2025 best-practice definitions name four situations where leaving the bed is not realistic: limited mobility, a restricted environment such as a dorm, barracks, or prison, chronic pain that requires extended time in bed, and chronic fatigue or a comorbid disease.
The substitute is called counter control: you stay in bed, but out of a sleeping posture. Sit up, put the pillow and the blanket aside, and read. The bed still stops being a place where you lie awake waiting, which is the part that mattered.
If the rules are not working, or you are not sure which component you actually need, you can talk to a sleep therapist about a full course. What you pay depends on your plan.
Rules five and six are the ones people skip, and they are the ones protecting tomorrow night. A fixed rise time keeps your body clock anchored, and a body clock that drifts is a separate problem from insomnia that produces the same complaint — see resetting your circadian rhythm. Skipping naps and lie-ins keeps your sleep debt where it needs to be at bedtime, which is the pressure that makes rule one possible in the first place.
Read together, the six rules are doing two jobs at once: cleaning up what the bed means, and protecting the drive that gets you to sleep in it.

By conditioning. Your bed is a cue, and it takes its meaning from what usually follows it. Nights spent lying awake in bed teach your brain that bed means alertness. Getting up when you cannot sleep, and returning only when sleepy, rebuilds the pairing so the bed predicts sleep again.
The clearest one is rule three: you have been in bed a while, you are awake and getting annoyed, so you get up, go to another room, read something dull under low light, and go back to bed only when you feel sleepy. If it happens again an hour later, you do it again.
Clinicians often say about 15 minutes, but that number is a later convention rather than part of the original instructions, which deliberately left the timing vague. Do not watch the clock to find out — the checking is its own arousal problem. Use the shift from lying there to lying there frustrated as your signal.
No, and the guideline separates them explicitly. The AASM suggests stimulus control can be used on its own to treat chronic insomnia, and in the same document suggests clinicians not use sleep hygiene as the whole treatment. A dark cool room is sensible advice; it does not change what your bed means to your brain.
Something dull, somewhere dim, with no deadline attached. Reading is the usual suggestion. Keep the lights low and the phone out of it, because bright light in the small hours works against the body clock you are trying to anchor. Go back to bed when you feel sleepy rather than when a set time has passed.
The AASM suggests it can, as a conditional recommendation. Multicomponent CBT-I is the only behavioral treatment in that guideline with a strong recommendation, so the package remains the stronger option. Stimulus control is a reasonable single component if a full course is not available to you.
