How Acupuncture Works Part 2. Acupunctures Influence on the HPA Axis: A Pathway to Stress Relief

How acupuncture works, its impact on the stress response is largely modulated in the HPA axis — How acupuncture works: the stress response

By Dr Luke McPherson (TCM), Acupuncturist Crows Nest

Have you ever wondered how acupuncture works? Here i will guide you through how acupuncture modulates stress.

Acupuncture, an ancient practice rooted in traditional Chinese medicine, has garnered modern scientific interest for its potential to influence the hypothalamic-pituitary-adrenal (HPA) axis—a central part of our body's stress response system. But how exactly does the gentle insertion of needles into specific points on the body impact this crucial biological pathway? Let's explore the fascinating mechanisms at play.

1. Reducing Stress Hormones

One of the primary ways acupuncture influences the HPA axis is by lowering levels of cortisol, the stress hormone produced by the adrenal glands. When we're stressed, our bodies produce cortisol to help manage the situation. However, chronic stress can lead to elevated cortisol levels, contributing to various health issues. Research indicates that acupuncture can help reduce cortisol levels, thereby easing the overall stress response and promoting relaxation.

2. Regulating Neurotransmitters

Acupuncture has a profound effect on the brain's chemistry. It can stimulate the release of neurotransmitters and neuropeptides, such as serotonin, dopamine, and endorphins. These chemicals are crucial for mood regulation and stress response. By balancing these neurotransmitters, acupuncture helps normalise the activity of the HPA axis, making us feel more balanced and less susceptible to stress.

3. Modulating Hypothalamic Activity

The hypothalamus is a small but mighty region of the brain that plays a critical role in the HPA axis. It releases corticotropin-releasing hormone (CRH), which initiates the stress response. Acupuncture can affect hypothalamic activity, altering the release of CRH and thus modulating the entire HPA axis. This adjustment helps in managing stress more effectively.

4. Normalising Feedback Mechanisms

The HPA axis functions through a feedback loop designed to maintain homeostasis. When cortisol levels rise, they signal the brain to reduce the production of CRH and adrenocorticotropic hormone (ACTH), thereby lowering cortisol production. Acupuncture may enhance the sensitivity of glucocorticoid receptors in the brain, improving this feedback inhibition. As a result, the body can better regulate cortisol levels, preventing an excessive stress response.

5. Anti-inflammatory Effects

Chronic inflammation is a known disruptor of the HPA axis, leading to an impaired stress response. Acupuncture is well-documented for its anti-inflammatory properties, which can reduce inflammatory cytokines—molecules that can interfere with the normal functioning of the HPA axis. By lowering inflammation, acupuncture helps maintain a balanced HPA axis function, supporting overall health and well-being .

Acupuncture’s influence on the HPA axis is a testament to the interconnectedness of our body's systems. Through a blend of hormonal, neural, and immunological pathways, acupuncture helps restore balance and mitigate the physiological impacts of stress. Whether you're seeking relief from chronic stress or simply looking to enhance your overall wellness, acupuncture offers a scientifically-backed pathway to a more balanced and peaceful state of being.
