I think this is a very important concept that needs to be better understood. As others have posted in this thread, I tend to work better - at least on certain tasks, when sitting in a busy cafe vs. at home where it's quiet. It's made me realize that certain people may have an optimal minimal amount of stimulus required, otherwise leading to restlessness - boredom. It would make sense that a system, body and mind, designed or optimized for a higher level of sensory input - when active and not sleeping - wouldn't just be able to "rev down" quickly, which perhaps would be more akin to a depressed state - or suppression/repression of where someone's systems naturally want to them to efficiency wise for the amount of stimulus they can process. A quiet classroom may be a terrible environment for some people to learn - yet is common practice for most school systems.
