When was the last time you sat by yourself, perfectly still and not thinking about anything for 30 minutes? Heck, when's the last time you did that for two minutes?

We are so bombarded with information and stimulation that most of us are mentally active almost all the time. If we're not working, we're watching TV, going online or otherwise occupying our minds.

When does the brain get to rest? Not when we're asleep, apparently. Scientists tell us that brainwave activity continues unabated through the night. We have plenty of ways to relax our bodies, but how about our overstimulated brains?

One activity that really seems to help is showering.

How many times have you heard about someone coming up with a great idea in the shower? I think that happens because, after you've finished with the soap and shampoo, your brain is relaxing. As you stand there rinsing, the brain has a few moments of blissful rest... and then the ideas begin to flow.

We can all benefit from turning off our brains once in a while. That could mean getting lost in an everyday activity, like showering or some menial task. Or learning meditation. Or just getting away from all the stimuli, breathing deeply and letting your mind drift aimlessly for a few minutes. Find whatever works for you and I think your mental powers will grow exponentially.

One time to not turn off your brain is from 7:30–9:15am, Saturday, May 5, at the AAO in Honolulu. That's when I'll be presenting "Practice Management & Leadership." I hope to see you there. For more information, click here.
