You Have a Dirty Mind

We’re learning more about why sleep is so important. According to an interesting set of recent studies, sleep provides your brain with the opportunity to essentially clean itself. One researcher compares your brain to an aquarium: “Think about a fish tank. If you have a tank and no filter, the fish will eventually die. So, how do the brain cells get rid of their waste? Where is their filter?” I’m an insomniac with seventy-five open browser tabs. My aquarium is a swamp.

+ “We are at the same place that the impact of smoking was on health 50 years ago when finally there was enough evidence that the surgeon general issued a report indicating that smoking was hazardous to people’s health.” That’s Harvard Med School’s Charles Czeisler who calls sleep the third pillar of health, along with exercise and eating well.
