Humans appear to be hard-wired for modest levels of anxiety as a fear-arousal warning mechanism. Anxiety may be characterized as uneasiness, fear, worry, and apprehension. Anxiety is a common psychological state in which the basic message is "get away from this situation". The state is usually accompanied by numerous physiologic components including surges of the hormone adrenaline, increased heart rate, and elevated blood pressure, and increased blood flow to the major muscle groups as the body prepares for "fight or flight".
These are all normal responses to environmental threats. The overall process is orchestrated by the amygdala and hippocampus, two regions of the brain's limbic system which process memory, emotional response, and spatial navigation. But for many people, if anxiety states become frequent and prolonged by various developmental circumstances in childhood and their teenage years, they may begin to respond to perceived rather than real threats. The anxiety state may persist and even become the default condition for the individual.
Those with chronic anxiety may experience chronic back pain,1,2 chronic muscular tension, fibromyalgia,3 headaches, chest pain, shortness of breath, and heart palpitations. Chronic anxiety may cause a person to anticipate the worst, to have ongoing feelings of dread, to be constantly irritable and tense, and to experience panic attacks. Eventually, the person may become worn out from the constant drain on their inner resources and a likely outcome is a depression. The person simply cannot take any more stress.
Chronic anxiety has a specific impact on the musculoskeletal system. Persistently elevated levels of adrenaline create ongoing tension in the postural muscles of the lower back and the weight-bearing, antigravity gluteal muscles, pelvic musculature, and hamstrings. The long-term results may include chronic lower back pain, inflammation of the sciatic nerve, and lumbar disc disease. Of course, any of these health problems create more anxiety for the person, establishing a vicious circle of anxiety, pain, more anxiety, and more pain.
Solutions for chronic anxiety usually require multidisciplinary holistic approaches. Nutrition, for example, is a key factor in restoring a person's homeostatic mechanisms. Significantly reducing one's intake of simple carbohydrates - soda, muffins, cookies, cake, fast food, and even juice - will often have a substantial impact. Making sure to have five servings of fresh fruits and vegetables every day will also provide great benefits.
Chiropractic care can frequently provide considerable assistance to those with chronic anxiety. By normalizing activity within the musculoskeletal system and reducing muscular stress and tension, chiropractic care helps eliminate an unnecessary source of biochemical and physiologic stress.
