Last week we posted on how worry can affect the lives of injured or disabled workers. In today’s post, we’ll talk about some of the specific effects of worry on the body.
The physical reactions to excessive fear and anxiety (worry) initiate a chain or cascade of pathological events by stimulating the amygdala area of the brain (fight/flight response), releasing neurotransmitters to the cortex. There, the fear or anxiety, whether real or imagined, is analyzed in detail and the analysis is returned to the amygdala where, in normal situations, the fear response is shut off by amino-butyric acid (GABA). GAD worriers may not have high enough GABA levels to shut off this pathway. Consequently, there are constant marked secretions of glucocortocoids and catecholamines that increase blood sugar levels. Marked levels of epinephrine and norepinephrine dilate blood vessels in skeletal muscles and other adrenergic (adrenal) stimulations that in turn create modifications in breathing, increased temperatures, sweating, decreased mobility of the stomach, bowels, and intestines, constrictions of the sphincters in the stomach and intestines.
Simply said, constant fear and anxiety result in debilitating amounts of stress hormones like cortisol (from the adrenal glands) and hormones that cause blood sugar levels and triglycerides (blood fats) to rise significantly. This process, if not shut off or modulated, can cause premature coronary artery disease, short-term memory loss, digestive problems, and suppression of the natural immune system. The scientific literature is now implicating constant stress, such as constant work stress or toxic fear and anxiety, in causing large weight gains in the midriff area which can greatly exacerbate orthopedic injuries, particularly of the spine or knees, and can lead to increased incidences of diabetes and cancer.
Worry causes increased mortality and morbidity. It is that simple.
For information on how to treat and avoid worry, check in with us later this week for the next installment in this 3-part series.
