Have you come across the term "nervous system regulation" lately? It seems to be popping up more frequently, at least in my corner of the internet. On one hand, this increased attention makes me quite happy, but on the other, it raises some concerns.
I'm thrilled to see a broader audience becoming familiar with the science behind the mind-body connection. Understanding how our nervous system works can profoundly impact our approach to managing burnout, chronic illness, trauma, and other stress-related symptoms. For those who have felt lost or dismissed by traditional healthcare systems, gaining insight into nervous system regulation can offer a glimmer of hope and a sense of control over their health journey.
Hope and a sense of control are powerful agents of change. Research consistently shows that when individuals believe they can influence their health, positive outcomes often follow. For example, studies on multiple sclerosis reveal that up to 71% of health-related quality of life is linked to the degree of perceived control over the illness experience [1].
Even without immediate changes in behavior, simply fostering hope can positively alter our physiology [2]. And when hope is paired with a belief in personal control, it naturally encourages health-promoting actions. For instance, if I believe that eating a nutritious diet will boost my immune system, I'm more likely to prioritize such foods. Conversely, if I lack hope or doubt my ability to make healthy choices, I’m less likely to engage in beneficial behaviors, depriving my body of essential nutrients.
Despite the benefits, I'm also concerned about the oversimplification of nervous system regulation in popular discourse. The narrative often boils down to "just reduce your stress through breathing" or "retrain your brain, and things will improve." While these strategies can be part of the solution, they are not a one-size-fits-all remedy. Some health coaches promote quick fixes to "master your nervous system" for superficial benefits like glowing skin, which can be misleading and potentially harmful. Unlike psychologists or psychotherapists who are bound by professional ethics, self-proclaimed nervous system coaches may not face consequences for their marketing strategies, which can sometimes do more harm than good.
Much of the current discussion about nervous system regulation focuses on the autonomic nervous system (ANS), a crucial component of our body's stress response. The ANS has two main branches: the sympathetic nervous system (SNS), responsible for "fight or flight" responses, and the parasympathetic nervous system (PNS), which promotes "rest and digest." However, labeling the SNS as "bad" and the PNS as "good" oversimplifies the reality. The truth is, we need a balance between these systems for optimal health.
Constantly activating the PNS isn't always beneficial. Excessive PNS activation can depress bodily functions, disrupt mood, impair immune function, and negatively affect digestion [3]. Similarly, chronic SNS activation can lead to adverse physiological changes. The goal should not be to favor one system over the other but to achieve a harmonious balance between the two.
