In these uncertain times, we are all exposed to extra stress at the moment. Stress from not knowing what tomorrow will bring, will I have a job, will someone I know get sick.
We are often asked how we, as chiropractors are able to help with stress, and this is an interesting question; especially at the moment. To answer this question, we are going to look at the impact of the chiropractic adjustment (spinal manipulation) on heart rate variability (HRV). HRV simply put, will measure the intervals between heart beats, and give us information about our sympathetic (fight or flight) and parasympathetic (rest & digest) nervous systems. (1) We need a good balance between theses system for a healthy response. A low variability is associated with increased risk for chronic disease. (2)
When we are stressed, our nervous system goes into a sympathetic dominance which can lead to an increase in our heart rate, increased muscle tone (especially in the neck), but decreases our ability to concentrate. (3, 4)
But back to the main question at hand, how can a chiropractor help me and my body with stress? Well, there have been a number of studies looking into how adjustments to the spine can influence the autonomic nervous system (parasympathetics and sympathetics). They suggest that adjustments to the neck (cervical spine) and low back (lumbar spine) will increase our parasympathetic response, which in turn will help manage that stress induced sympathetic response. (5-8)
So, if you, or someone you know, is struggling with their stress levels, please give our office a call to see how we can help you.
