‘Power naps’ may boost right-brain activity

I haven’t noticed that I get any smarter after a nap, but I have noticed that I can often get better ideas by going for a walk where I sort of let my brain run on autopilot for a while. I suspect that the benefit is from relaxing the brain and allowing disparate ideas/concepts to ‘collide’ and reassemble into different patterns that leads to the improvements. Sometimes (perhaps often) logical thinking based on past experience will lead to a successful result, but, to me, the more complex or novel the problem the more creative the result needs to be and the better an approach like this would be. Based on my experience in life, I doubt such naps would help people in the rather mundane labor-intensive work like assembly lines.
Some of the best stuff I read is written on the inside of my eyelids. 😉
