Getting enough high quality sleep is important for cognitive productivity. I’ve developed a technique called the cognitive shuffle. This is a technique that you can use in bed to ease you into sleep. I always try to make it clear that it is not a silver bullet. I recently posted an article on mySleepButton about how it can be used with acceptance and commitment therapy. “Acceptance and commitment” is a “third wave” psychological framework that aims to help people better relate to the content their minds generate. (That framework has some dubious “behavioral” theoretical baggage which you can safely ignore.)
