What Is Insomnia?

The underlying biological basis of insomnia is something called the hyper arousal model. In more common speak, it's that you're jacked, you're wired in terms of your system. And one separation of some of those branches is the separation of what we call the sympathetic from the parasympathetic nervous system. That branch of the nervous system has to disengage for you to fall asleep easily and then stay asleep across the night.
