Immune Response to Stress: How Stress Impacts Your Immune System and What You Can Do About It


Have you ever wondered if stress could be a major cause of immune dysfunction? Is getting sick a signal from your body that something—whether physical, emotional, or mental—needs to shift in order to reset and fight against illness? Our bodies have an innate ability to combat diseases as long as they are in a state of homeostasis. However, when this balance is disrupted, the body manifests signs of imbalance, whether they are physical (like colds or headaches), emotional (anger, fear, frustration), or mental (anxiety, depression, panic).

The body's inner wisdom acts as an alarm, prompting us to address underlying factors that might be leading to physical, emotional, or mental distress. Understanding the physiological mechanism of stress and immunity can offer insight into how these two are deeply connected.


The Gut-Immune-Stress Connection

There is a complex communication network between the gut microbiota, mucosal lining of the intestines, endocrine system, immune system, and central nervous system (brain) via the gut-brain axis. This connection means that stress and immune function are bidirectional; a change in local immune function can affect stress levels, while prolonged stress can lower immune responses, particularly in the gut.


When stress first occurs, the immune system slows down as the body focuses on managing the stressor. If stress persists, immune deficiency sets in, making the body more susceptible to infections. This ongoing cycle often results in swelling and inflammation in various tissues, increasing overall discomfort and vulnerability.


Case Study: Immune Dysfunction in a Young Patient

A 14-year-old female patient visited the clinic with recurring headaches, sinus congestion, a history of frequent colds, and environmental allergies. Her mother shared that she had been a forceps delivery and had experienced these symptoms since infancy, with no relief from traditional medical interventions.


Upon assessment, it was found that her cerebrospinal fluid production and reabsorption cycle was compromised, limiting fluid drainage from her cranium. After four sessions focusing on regulating her autonomic nervous system and restoring proper drainage of fluids in her cranium and spine, the patient experienced significant improvements. She reported fewer headaches, no colds since beginning therapy, and enhanced focus and concentration in school. Her mood improved, and she felt happier and less irritable.

This case exemplifies how both internal and external stressors can profoundly impact the immune system. A thorough evaluation aimed at identifying root causes, rather than masking symptoms with medication, can lead to long-lasting improvements in health.


Holistic Ways to Boost Your Immunity

1. Mindfulness

Mindfulness helps you stay in touch with your true essence, allowing you to listen to the messages of your body and maintain a healthy balance. By focusing on the present moment, you can reduce stress and improve your immune response.

Method: Take 3–5 conscious breaths, focusing from your feet up through your pelvis, diaphragm, chest, shoulders, and head. Check in with these major areas and observe what your body feels like. Repeat this practice when you notice stress building.


2. Movement and Diet

Movement, even as simple as a short walk in nature, can boost your immunity and lower stress. Breathing fresh air and connecting with nature has been shown to drastically reduce stress and strengthen the immune system. Additionally, a diet rich in whole foods like vegetables, fruits, nuts, and lentils supports gut health and boosts immunity, while cutting down on processed foods.


3. Manual Therapy

Manual therapies that target organs involved in immune function—such as the skin, thymus, lymph nodes, spleen, and mucous membranes—can help improve organ mobility and function, restoring the body to homeostasis. These therapies are designed to enhance the body’s natural immune response, relieving stress and promoting overall health.


Conclusion

Stress is a powerful factor in immune dysfunction, and learning to manage it effectively is crucial for maintaining health. Whether through mindfulness, movement, diet, or manual therapy, there are several ways to support your body’s natural immune response and help it return to homeostasis. Rather than just suppressing symptoms, addressing the root cause of stress can lead to lasting health and well-being.


The immune response to stress is more than just an isolated issue—it is a window into your overall health.
