As a health psychologist, I know that our brains excel at making associations between things. As a person with common sense, I know that people tend to really like sleeping and having sex. One of the problems of chronic sleep issues is that the bedroom becomes associated with lots of different activities: watching TV, checking FaceBook, working on a laptop, or laying awake wishing you could sleep.
Clean the slate! Move the TV out of the bedroom and move all non-sleeping or sexing (is that even a word?) activities to other rooms or, if you’re tight on space, at least not on the bed. When getting into bed is only associated with sleepy time (or sexy time), it helps our minds relax and our brains send signals that it’s time to fall asleep.
