Stress is one of the most common reasons for visits to the doctors office today. Whenever we are stressed our body produces a hormone known as 'cortisol' that gives us the energy we need to fight or flee from whatever it is that is inducing the stress.
The problem today is that, for the most part, our stress isn't being caused by things that we can punch, run, and hide from, but rather fear mongering, lack of sleep, overworking ourselves, and poor diet.
