CBT-I Stimulus Control — Get Out of Bed
Bootzin's stimulus-control protocol (1972) is the highest-evidence behavioral intervention for middle-of-night waking. It works by breaking the conditioned association between your bed and wakefulness — if you're lying awake, the bed is training your brain to be alert there. Use this when you've been awake roughly 20 minutes and lying there isn't working.

The protocol
Step by step
- 01
Stop watching or checking the clock — estimate 20 minutes of wakefulness, then act. Clock-watching increases arousal and makes the wait feel longer.
- 02
Get out of bed. Do not negotiate with yourself about whether this time might be different. It won't be.
- 03
Go to a different room, or at minimum move to a chair well away from the bed. The physical separation from the sleep surface is the mechanism — do not skip it.
- 04
Keep the lights dim — a single low lamp is enough. Bright overhead light suppresses melatonin and signals daytime to your circadian system.
- 05
Do something quiet and low-stimulation: a paperback novel, a magazine, light stretching, or simply sitting. No phone, no tablet, no laptop — backlit screens raise alertness and the content is engineered to keep you engaged.
- 06
Do not eat a full meal, start a work task, or do anything that rewards being awake. The goal is boring wakefulness, not productive wakefulness.
- 07
Wait for a clear physical signal of sleepiness — heavy eyelids, head nodding, difficulty focusing on the page. This is different from feeling tired or frustrated.
- 08
Return to bed only when that sleepiness signal arrives. Get in, assume your usual sleep position, and let sleep come without forcing it.
- 09
If you're still awake after another estimated 20 minutes in bed, repeat the sequence: get up, dim room, boring activity, wait for sleepiness.
- 10
In the morning, get up at your fixed wake time regardless of how many times you repeated the cycle. Consistent wake time is what rebuilds sleep pressure over the following nights.
Modifications
Variations
Shift-worker adaptation — if your sleep window is daytime, blackout curtains in your designated out-of-bed chair area matter as much as in the bedroom. Use a sleep mask if a separate dim room isn't available. Your 'boring activity' must be genuinely low-stimulation; daytime noise and light make this harder, so earplugs and a white-noise machine in the sitting area help maintain the protocol's intent.
Postpartum compressed version — if you're co-sleeping or can't leave the room without waking the baby, move to the far edge of the bed or a bedside chair rather than another room. The partial separation still weakens the bed-wakefulness association. Accept that full protocol fidelity isn't possible in this phase; even a partial version reduces the conditioned arousal over time.
Small-apartment workaround — if there is no separate room, designate a specific chair as your out-of-bed spot before you go to sleep. Face it away from the bed. Keep a blanket and a paperback there in advance so you don't have to make decisions at 3am. The pre-staged setup removes the activation cost that causes people to skip the protocol when exhausted.
Partner-disagreement workaround — if your partner objects to the light or movement, negotiate a pre-agreed signal (a gentle tap) so they aren't startled, and keep a small clip-on book light and a blanket staged in the hallway or bathroom. Doing the protocol in a bathroom with the door closed and a dim nightlight is suboptimal but functional.
Note
Not recommended as a standalone first-line intervention for people with severe anxiety disorders where getting out of bed at night significantly escalates arousal or panic — the physical act of leaving bed can become its own anxiety trigger. For those patients, the worry-window or cognitive restructuring components of CBT-I should be introduced first. Not appropriate during acute medical illness where getting out of bed carries fall risk (post-surgical recovery, severe vertigo, frailty). People with bipolar disorder should not undertake CBT-I sleep restriction protocols without psychiatric supervision due to mania-induction risk; stimulus control alone is lower-risk but should still be coordinated with their treatment team. Stimulus control is not a substitute for evaluation of underlying sleep disorders — if middle-of-night waking is accompanied by gasping, witnessed apneas, or significant snoring, rule out obstructive sleep apnea before attributing waking to conditioned insomnia.
