Use the bed only for sleep (and sex)

Reserve the bed strictly so the brain learns to associate it with sleepiness, not wakefulness.

Why it works

Through classical conditioning, the brain associates places and contexts with states. When the bed is regularly paired with lying awake, worrying, scrolling, or watching television, it becomes a cue for arousal and anxiety rather than sleep. Restricting the bed to sleep breaks the unwanted association and begins building a new one: bed → drowsy.

How to do it

1. Do all reading, screens, and non-sleep activities in a different chair or room.
2. Go to bed only when genuinely sleepy — not just tired or at your normal hour.
3. If you use a bedroom workspace, face the desk away from the bed or use a divider.

Evidence

Stimulus control therapy is consistently rated among the most effective single-component behavioral treatments for chronic insomnia in clinical reviews and is a first-line component of CBT-I. (rct)

Most evidence is in clinical populations with diagnosable insomnia; benefits for subclinical poor sleepers are likely but less directly studied.

Common mistake

Treating the bedroom as a general relaxation zone — using it to watch calming shows or read stressful news, which undermines the association you are trying to build.
