My bedroom is multipurpose but analyze: do I need complete separation? Map my bedroom activities: work, TV, phone, reading, sleep. Calculate: if I ONLY slept in bedroom (no other activities), would sleep improve? Show me the association reconditioning: bedroom = sleep only, retrain the brain. Give me the implementation: remove these activities from bedroom. Include: whether my brain associates bedroom with wakefulness, how to rebuild sleep-bedroom association, and if I need strict separation or if some activities are okay.
