Chiropractic care aims to reduce sympathetic nervous system (stress or "fight or flight") tone by promoting balance with the parasympathetic nervous system ("rest and digest"). Adjustments, particularly to the upper cervical spine, may decrease brainstem pressure and enhance vagal nerve activity, which activates the parasympathetic system. This improves symptoms of stress, such as high blood pressure, anxiety, and digestive issues, by shifting the body into a more relaxed state.
How Chiropractic Care May Reduce Sympathetic Tone
Restoring Autonomic Balance:
The primary goal of chiropractic care is to achieve a healthy balance between the sympathetic and parasympathetic nervous systems.
Spinal Misalignment and Nervous System Stress:
Misalignments (subluxations) in the spine can put pressure on the nervous system, leading to an overactive sympathetic response.
Upper Cervical Adjustments:
Adjustments to the upper cervical (neck) spine may reduce pressure on the brainstem, which can decrease sympathetic overactivation and help the body transition from "fight or flight" to "rest and digest".
Enhancing Parasympathetic Function:
By relieving pressure on the nervous system, chiropractic adjustments allow the parasympathetic nervous system, particularly the vagus nerve, to function more effectively.
Reducing Stress Hormones:
Research suggests that chiropractic care may help reduce cortisol levels, a key stress hormone, thereby mitigating the negative effects of chronic stress on the body.
Signs of Overactive Sympathetic Tone:
An overactive sympathetic system, often a result of chronic stress, can manifest as:
- Fatigue
- Headaches
- Digestive problems
- Poor immune function
- Pain
Potential Benefits:
By promoting a more balanced nervous system, chiropractic care may contribute to:
- Reduced anxiety and improved emotional regulation
- Better sleep quality
- Improved digestion
- Enhanced overall nervous system function and well-being
