Stimulus control for insomnia: reconnect bed and sleep

Stimulus control: reconnecting your bed with sleep

Stimulus control is a set of simple instructions to make your bed a signal for sleep again, rather than for wakefulness and tension: go to bed only when you're sleepy, get up when sleep won't come, and keep a fixed wake-up time. Together with sleep restriction, it is one of the most effective components of CBT-I^[3]^[4].

Key points

After months of sleepless nights, your bed can become a signal to stay awake: the method breaks that link^[2].
The bed is for sleep (and intimacy): no screens, work or rumination in bed^[2].
If sleep doesn't come, get up and go back when you feel sleepy again^[2].
Recommended by the American Academy of Sleep Medicine, and among the most effective components of CBT-I^[1]^[3]^[4].

Why it works

The brain learns by association. For a good sleeper, getting into bed brings on sleepiness. After months of insomnia, the opposite happens: the bed is linked with hours of wakefulness, frustration and worry. You can be nodding off on the sofa, then find yourself wide awake the moment you lie down in bed.

Stimulus control aims to help you relearn the “bed equals sleep” association, by keeping the time you spend awake in bed to a minimum^[2].

The instructions

Go to bed only when you feel sleepy: heavy eyelids, yawning, head nodding. Feeling tired isn't enough on its own.
The bed is for sleep and intimacy, not for screens, work, eating or going over the day.
If you're not asleep after about twenty minutes (an estimate, without looking at the clock), get up, go to another room and do something quiet in soft light.
Go back to bed when you feel sleepy again. Repeat as often as you need to, in the middle of the night as well as when you first try to fall asleep.
Get up at the same time every morning, however the night went, weekends included.
No naps, to save your drive to sleep for the night.

These instructions are set out in the American Academy of Sleep Medicine's recommendations^[2].

In practice: what to do once you're up

A quiet, low-key activity: reading a paper book, listening to gentle music, doing a crossword, folding laundry.
Dim, warm light; no phone or bright screens.
Nothing too rewarding, and no work: the aim is to wait for sleep, not to catch up on your day.
Get ready the day before: a blanket, a soft lamp and a book in the living room make getting up at night easier.

Take care at night

Getting up in the dark, half asleep, puts you at risk of falling: keep a night light on to show the way, especially if you are older or take medication to help you sleep.

Combined with sleep restriction

The two methods complement each other and are often used together: sleep restriction reduces your time in bed to consolidate sleep, and stimulus control reduces the time you spend awake in bed. Together, they form the behavioural core of CBT-I^[3]^[4], the recommended first-line treatment for chronic insomnia in adults^[5].

Note the times you get up at night in your sleep diary: week after week, it shows how your time awake in bed is changing.

Common difficulties

“I'll get even less sleep.” For the first few nights, perhaps. But lying in bed battling it keeps insomnia going; getting up is an investment in the nights ahead.
“It's cold, and I don't want to get up.” Set up your night-time corner in advance: it's easier when everything is ready.
“I can't tell if twenty minutes have gone by.” No need for a stopwatch: as soon as you feel sleep isn't coming and tension is building, get up.

Frequently asked questions

How long should I stay in bed before getting up?

About twenty minutes, estimated without looking at the clock. As soon as you feel sleep isn't coming and you're getting frustrated, get up.

Can I read in bed?

During therapy, it's best to keep the bed for sleep and intimacy. Reading in an armchair before bed, then going to bed when sleep arrives, works better.

What if I wake up at 4 am?

Same instruction: if sleep doesn't come back after about twenty minutes, get up, do something quiet, and go back when you feel sleepy. Keep your usual wake-up time.

How long before it works?

It generally takes a few weeks of regular practice, often alongside sleep restriction, as part of a six-to-eight-week CBT-I programme.
