The mind-body connection is well known to produce physical manifestations of emotional distress. Anxiety, in particular, is expressed through both psychological and bodily symptoms, and has been linked to a range of physical health problems that can seriously affect your quality of life. When you experience anxiety, changes in neurotransmitter activity flood your brain with stress hormones, affect breathing and muscle tension, and re-route blood to the brain, moving it away from abdominal organs as your primitive self-preservation apparatus kicks in and puts you on high alert. Of particular concern is the elevation of cortisol levels:
Cortisol, the primary stress hormone, increases sugars (glucose) in the bloodstream, enhances your brain’s use of glucose and increases the availability of substances that repair tissues. Cortisol also curbs functions that would be nonessential or detrimental in a fight-or-flight situation. It alters immune system responses and suppresses the digestive system, the reproductive system and growth processes. This complex natural alarm system also communicates with regions of your brain that control mood, motivation and fear.
The body’s self-regulating mechanisms typically return your body to a state of equilibrium after feelings of fear have passed. However, the continuous exposure to stress hormones, including cortisol, caused by chronic anxiety can produce adverse health effects affecting your entire body, including your digestive, cardiovascular, and reproductive systems.
