A Culture of Stress

This article does a nice job explaining the function and impact of the stress hormone, cortisol, which is helpful if introduced into the body on a limited basis because it prepares the body for action. This process is normal when we experience stress as it pops up from time to time. What is not normal is when we perceive stress all the time by perpetually imagining worst case scenarios. Under these conditions cortisol can become toxic with side effects like agitation, fatigue, poor focus, lowered self-esteem, clinical anxiety, and major depression.
