Long before humans had developed any kind of civilization, the world was a dangerous place...

Reacting quickly to threats could mean the difference between life and death. That's why human brains are hard-wired to respond automatically to threats.

This automatic response to a threat is called stress. Almost before we are aware of a threat, our hearts are pounding faster, our breath is coming faster, our muscles are ready for action and our senses are on full alert.

In today's world, we are constantly exposed to potential sources of stress and worry. Constant exposure to stress can play havoc with our lives, our bodies and our relationships. Learning how to recognize stress and to cope with it in a healthy way can measurably improve our lives and the lives of those around us.
