Get out of bed when you can not sleep

Leave the bed after roughly 20 minutes of wakefulness to avoid reinforcing the awake-in-bed association.

Why it works

Every minute spent lying awake in bed deepens the pairing between the bed environment and the awake state. Getting up breaks the reinforcement cycle and, after a period in a calm, low-stimulation space, allows sleepiness to rebuild before you return. The discomfort of getting up is the mechanism — it makes the bed a place you re-enter only when sleep is likely.

How to do it

1. Set a rough 20-minute window in your mind (do not watch the clock) and get up if sleep has not come.
2. Move to a dim, quiet space and do something calm and non-stimulating — gentle reading, stretching.
3. Return to bed only when you feel genuinely drowsy again.

Evidence

The get-out-of-bed instruction is one of the core stimulus control rules; clinical trials of full stimulus control therapy show it reduces sleep onset latency and wakefulness after sleep onset better than sleep hygiene alone. (rct)

Some people find the rule anxiogenic; brief mindfulness or relaxation in bed is an acceptable adaptation if strict get-up is too distressing. Clinical adaptation is normal.

Common mistake

Getting up and doing something stimulating — bright lights, phone, email — that activates the brain further and makes return to sleep harder.
