Chiropractic and the Immune System

Maintaining a strong immune system is a key focus for maintaining health today, as a well maintained immune system can protect the body against infections, viruses and day-to-day health challenges. 

While most people are aware of the benefits of healthy eating, regular exercise and restful sleep for maintaining a robust immune system, few people understand that the nervous system is also essential for controlling immune responses. By concentrating on the spine and its alignment, chiropractic care seeks to support the nervous system so that it can operate freely, potentially enabling the body to react to stress and disease more efficiently.

Chiropractors work with misalignments in the spine, which can in turn influence the brain's ability to communicate with the body. As such, enhancing spinal alignment may support the body's natural regulatory processes because the immunological and neurological systems are closely linked. 

The nervous system and immune system connection

There is growing scientific evidence linking immune function to the nervous system. Researchers in the subject of neuroimmunology describe how neuronal and hormonal mechanisms facilitate brain-immune communication. The inflammatory reflex, for example, is a neurological mechanism in which the vagus nerve signals directly to the immunological line of control and modulates cytokine synthesis to assist regulate immune responses.

Similarly, it is recognised that hormones produced by the brain through the hypothalamic-pituitary-adrenal (HPA) axis affect immunological responses, particularly in times of stress. 

Spinal alignment and nervous system function

The idea that the spine serves as both a structural support structure and an essential conduit for nervous system communication is at the heart of chiropractic care. The spinal cord, which transmits signals from the brain to the rest of the body, is housed and shielded by the spinal column.

The goal of gentle chiropractic adjustments is to address these misalignments in order to eliminate nerve interference and restore appropriate alignment. As a result, the neurological system functions more effectively, enabling clear communication between the brain and the tissues, glands and organs involved in immune defence. Simply said, the body may be better supported in maintaining normal communication pathways that help regulate immune responses when the nervous system can communicate without hindrance.

Evidence supporting immune function benefits

Numerous studies suggest that chiropractic adjustments may have a positive impact on certain immunological markers, though research is still emerging and findings should be considered promising rather than conclusive. For example, a 2023 study published in the Journal of Chiropractic Medicine found that within just 30 minutes of cervical adjustments, patients showed significantly higher levels of secretory immunoglobulin A (SIgA), an antibody that plays a crucial role in the body’s first line of defence.

Historical cohort observations also hint at potential links with certain immune markers. Over a three-year period, patients receiving chiropractic care showed differences in some immunological indicators compared with individuals not receiving such care.

Broader clinical observations suggest that spinal adjustments may contribute to overall immune health indirectly. Reviews indicate that chiropractic care may contribute to improved mobility, reduced stress and overall physical wellbeing, which can indirectly support immune health.

Integrating chiropractic into immune supportive hygiene

Here are practical ways chiropractic care may support immune health:

• Improved Nervous System Communication - The nervous system can transmit and receive messages more effectively when the spine is in the right alignment. Enhanced communication may support the body’s ability to regulate how it responds to everyday health challenges. Clearer neural communication may support the body’s ability to regulate its normal immune responses.

• Immune Marker Improvements - Certain biological indicators of immunological health may be impacted by chiropractic adjustments, according to research. For instance, research has shown that following spinal adjustments, there are temporary increases in secretory immunoglobulin A (SIgA), an antibody that guards against infection on the body's surfaces. Additionally, historical accounts indicate that those who received chiropractic care on a regular basis have observed differences in immune markers, although more research is needed to fully understand these effects. These results suggest some physiological benefits, but additional research is required.

• Holistic Support for Stress Reduction - Chiropractic therapy addresses the effects of stress on the body in addition to the spine. By raising levels of the stress hormone cortisol, emotional and physical stress such as tense muscles or bad posture both gradually impair immunity. Adjustments from a chiropractor can assist to calm the nerve system and relieve pressure, which may reduce stress and help support normal immune system function.

• A Complementary Role in Healthy Living - Chiropractic care shouldn't be seen as a substitute for tried and true immune boosting habits like eating a healthy diet, exercising frequently, getting enough sleep listening to your doctor. Rather, it can be used as an extra instrument to support these initiatives. Chiropractic adjustments may help the body fully benefit from other healthy lifestyle choices by maintaining the nervous system's optimal performance.

Mechanisms at play: Stress reduction & holistic health

One of the most important things that can impair immunity is stress. The body produces more cortisol, the main stress hormone, when it is experiencing extended physical or emotional stress. The body finds it more difficult to fight off infections when cortisol levels are high because they inhibit immune cell activation. Furthermore, long-term stress maintains the sympathetic nervous system in a "fight or flight" mode, which depletes resources for immune defence, healing and repair. 

By enhancing the nervous system's functionality, chiropractic therapy may help offset these consequences. Chiropractors can ease muscle tightness and nerve discomfort by gently realigning the spine. These conditions are frequently brought on by stress. In addition to enhancing mobility and posture, this also lessens the body's stress reaction. A transition from sympathetic dominance ("fight or flight") to parasympathetic balance ("rest and repair") may be encouraged by chiropractic adjustments, as many patients report feeling more at ease afterward.

This change is significant because the parasympathetic nervous system promotes digestion, immunological function and restful sleep all of which are critical for resilience. Reducing stress also lowers cortisol, which improves the performance of immune cells including lymphocytes and natural killer cells. In this sense, by assisting the body in better managing stress, chiropractic adjustments may indirectly support immunity. A comprehensive strategy for boosting the immune system and preserving long-term wellbeing may include chiropractic adjustments in addition to lifestyle choices like mindfulness, consistent exercise and a healthy diet.

Final thoughts

The relationship between the immune system, neurological system emphasises how crucial it is to consider factors other than the obvious when considering health. Growing data suggests that chiropractic care may support aspects of immune system regulation by potentially enhancing nervous system communication, lowering stress levels assisting the body in maintaining balance, though more research is still required. Crucially, chiropractic care can be a beneficial supplement to a healthy lifestyle that consists of regular exercise, a balanced diet and enough sleep, but it cannot take the place of medical care.
