Stress And How It Affects Your Health
by Dr. Shaila Callaghan
It is widely known and supported by research that stress is a key contributor to disease and illness; therefore, the management of stress is essential for optimal health! Stress, simply, is a human survival mechanism and is a normal and healthy reaction. Through a complex interaction of hormones, it acts to protect us from danger, be it internal (I’ve got a cold, again!) or external (That car is coming right at me at 80km/hr!).
In the time of our ancestors, the stress response was integral to survival – they were met with a single “fight or flight” episode, and acted accordingly. This episode would be dealt with immediately, within 90 seconds. In today’s world, life is not so simple. We are bombarded with many smaller, yet chronic, stresses on a daily basis – strict deadlines, lack of sleep, overwhelming chemical stresses due to obesity and fast food intake, etc. Even though our society has advanced in many aspects, our bodies have not adjusted significantly to account for the changes in our stressors.
Humans turn on the stress response for purely psychological reasons, and we are doing it non-stop. We are bombarding our bodies with stress hormones to such a point that the stress response becomes more damaging than the stressor in the first place. When these hormones are present in our system, our body acts “stressed” and turns off other important systems, such as our reproductive system and our immune system, in order to preserve the energy for the stress response. In the simplest terms, stress disrupts our body’s ability to heal and repair itself.
The following are some significant research findings in the areas of stress:
The arteries of stressed people have more plaque than the arteries of non-stressed people.
Stress affected the hippocampus (area of the brain responsible for learning and memory) of rats and caused memory loss – short term memory was more affected and decreased the ability for learning.
People in subordinate jobs have more stress hormones and decreased levels of dopamine (the ‘feel-good’ hormone) in the blood and brain.
Chronic stress results in increased fat/weight deposition, and this fat is more concentrated along the midline.
Maternal stress hormones are passed on to the fetus, creating a footprint for unhealthy habits in the adult.
Stress, by way of stress hormones, increases the rate of DNA breakdown, causing faster aging.
As a chiropractor, I am faced every day with patients who are showing significant signs of stress physically. Chiropractic is one way to alter the way your body handles stress. I recommend meditation and relaxation techniques for the majority of these patients as well. We need to begin to value stress reduction in order to promote a healthy lifestyle and longevity. Now is the time to take significant action
