CBT-I lesson 3: retraining bed for sleep

After months of poor sleep, bedtime can feel like a battle. You lie down, and your mind switches on. The bed has become a place for worrying and watching the clock.

This lesson helps you undo that. You will learn a short set of rules that doctors call stimulus control. They teach your brain to link the bed with falling asleep again, not with lying awake. It works hand in hand with the sleep window from lesson 2.

Why this step matters

Your brain learns by linking things that happen together. If you often lie awake in bed, your brain starts to treat the bed as a place for being awake. Just getting into bed can make you feel alert and tense.

Stimulus control is built to break that link. It also keeps your daily rhythm steady with a fixed wake-up time.¹ Over a few weeks, the bed becomes a strong signal for sleep again.

The American Academy of Sleep Medicine (AASM), a group of sleep doctors, suggests stimulus control as a treatment on its own. Its review found 8 trials, and more people who used it no longer had insomnia afterward. The AASM rated the quality of that evidence as low, because the studies were small or had flaws.¹ It works best as part of full CBT-I, which the AASM and Veterans Affairs both strongly recommend.^1,4

Evidence: stimulus control on its own Moderate evidence full CBT-I Strong evidence

What about older adults? A short program called brief behavioral therapy for insomnia (BBT-I) uses the same core parts as CBT-I, including stimulus control and a sleep window. It leaves out the thinking part.⁴ In one trial, 79 older adults with insomnia and other health problems got either BBT-I from a nurse or printed sleep advice. After four weeks, about 2 in 3 people in the BBT-I group (67%) improved, compared with 1 in 4 (25%) in the advice group. The gains lasted at least six months.⁵

The rules for retraining your bed

1. Go to bed only when you are sleepy. Sleepy means your eyelids feel heavy, your head nods, or you keep yawning. Tired, worn out, or bored is not the same. Also wait until your sleep window from lesson 2 has started.^1,2
2. Use the bed only for sleep and sex. Do not read, watch TV, use your phone, eat, or work in bed.^1,2 If you can, do these things in another room.
3. If you cannot fall asleep, get up. Do not lie there trying harder. If you are still awake after what feels like about 30 minutes, or sooner if you feel wide awake or upset, leave the bed.³ Go to another room if you can.³
4. Do something calm in dim light. Pick a quiet activity that is a little boring. See the list below. Avoid bright screens, work, and anything exciting.
5. Go back to bed only when you feel sleepy again. If you still cannot sleep, get up again. Repeat as many times as you need to.
6. Use the same rule when you wake in the night. If you wake at 3 a.m. and cannot drift back off, follow steps 3 to 5.
7. Get up at the same time every morning. Keep your wake-up time all 7 days, no matter how little you slept.¹
8. Skip naps for now.¹ Napping uses up the sleep pressure you need at night. If you are very sleepy and need to drive, safety comes first. Talk with your clinician about a short planned nap.

Don't watch the clock. Checking the time can make you more anxious. Turn the clock away and put your phone out of reach. Just guess. Feeling alert or frustrated is your signal to get up.

What to do when you get up

Before tonight, set up a "sleepy spot" in another room. A comfy chair, a warm robe or blanket, and a soft lamp are enough. Choose a few quiet activities ahead of time, such as:

• Reading a familiar book or magazine (not a thriller)
• Listening to calm music, an audiobook, or a slow podcast
• Simple handwork, like knitting, or a word puzzle
• A slow breathing or relaxation practice, like the body scan or muscle relaxation

Avoid bright light, email, news, alcohol, and caffeine. If worries keep you awake, write them on a notepad and set them aside. Lesson 4 teaches more ways to calm a busy mind.

Staying safe when you get up at night

What the first weeks feel like

The first few nights can be hard. You may get up several times, feel annoyed, and sleep less than usual. That is part of how the rules work. Less time awake in bed builds sleep pressure for the next night.

Keep your wake-up time steady, even after a rough night. Most adults need 7 or more hours of sleep, and adults 65 and older need about 7 to 8.⁷ You do not need to get there right away. First the sleep you get becomes more solid. Then your sleep window can grow, as in lesson 2.

Common problems

I fall asleep in the chair. Is that a problem?

If you notice yourself nodding off, go back to bed right away. Try not to spend the whole night on the couch or in a recliner. The goal is to fall asleep in bed.

I have always read or watched TV in bed to fall asleep. Do I have to stop?

For now, yes. Moving these habits out of bed is a key part of retraining it.^1,2 Read in your chair until you feel sleepy, then go to bed.

I get up again and again and still cannot sleep.

Keep going, and keep your wake-up time steady. If you are not better after several weeks, see your doctor or a sleep specialist. Sleep apnea, restless legs, pain, or a medicine side effect may be part of the problem. See Sleep apnea, Restless legs syndrome, and Medicines and mood.

I care for someone with dementia who wakes at night. Can I use these rules?

These rules are for your own insomnia. They are not meant for a person with dementia, who may get confused or fall when walking at night. For help with their sleep, see Sleep problems in dementia. For your own rest, see Caregiver stress.

Poor sleep is making me feel hopeless or very low.

Insomnia and low mood often go together, and both can be treated. See Sleep, mood and anxiety and talk with your doctor. If you are thinking about suicide or harming yourself, call or text 988 any time. In an emergency, call 911.

Next step

In lesson 4: calming thoughts about sleep, you will learn ways to quiet worry and the "what if I never sleep again" thoughts that keep you awake. Then lesson 5 covers winding down and staying on track. You can also go back to lesson 2 or the CBT-I overview.
