You lie down tired and within minutes your brain is replaying the day and rehearsing tomorrow. Cognitive behavioral therapy for insomnia (CBT-I) treats this directly: it reshapes the thoughts and habits around sleep so the bedroom becomes a cue for rest, not for problem-solving.
Offload the day before bed
Based on cognitive behavioral therapy frameworks, a brief evening journal externalizes the looping thoughts. Once they're on the page, the bedroom can return to being a place to sleep. According to 2026 psychological research, CBT-I is as effective as medication for chronic insomnia and lasts longer after treatment ends.
- Set the same wind-down time and close screens.
- Write the single thought looping in your head.
- Note one thing that went okay today.
- State tomorrow's first small step so the brain can stop planning.
Two minutes is enough. The point is the association, not the length β bed starts to mean sleep again because the mental offloading already happened on the page.
