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.
