Chronic pain affects millions of people worldwide. It is estimated that 20% of adults suffer from pain globally, with 10% newly diagnosed with chronic pain each year. For many, conventional painkillers come with a frustrating trade-off: they either lose effectiveness over time or bring unwanted side effects like dependency and drowsiness. This has pushed patients and researchers alike to look for alternatives that work with the body rather than against it.
Acupuncture, a practice rooted in Traditional Chinese Medicine, has long been dismissed by skeptics as little more than a placebo. But modern neuroscience tells a different story. When those thin needles are inserted into specific points on the body, they trigger a cascade of biochemical responses, most notably the release of endorphins and enkephalins, the body’s own natural painkillers. Understanding this mechanism reveals why acupuncture isn’t just tradition; it’s biology at work.
Your Guide to Endorphins and Enkephalins
Endorphins and enkephalins are endogenous opioid peptides, chemicals your body produces on its own that bind to opioid receptors in the brain and spinal cord.
- Endorphins are best known for producing the “runner’s high.”
- Enkephalins act more locally, modulating pain signals at the point of injury or stimulation.
- Both work by blocking the transmission of pain signals and altering how the brain perceives discomfort, without the side effects associated with pharmaceutical opioids.
How Acupuncture Triggers Their Release
When a needle is inserted at a specific acupoint, it creates a controlled micro-stimulus in the surrounding tissue and nerve fibers.
- This stimulus travels along afferent nerves to the spinal cord and brainstem.
- It activates the periaqueductal gray (PAG) and hypothalamus, regions directly responsible for endorphin and enkephalin production.
- Research using needle electromyography and neuroimaging has consistently shown measurable increases in beta-endorphin levels following acupuncture sessions, particularly with low-frequency electroacupuncture stimulation.
Needles Aren’t the Only Trigger
This same neurochemical pathway explains why a modern Acupuncture laser therapy clinic can achieve comparable results without inserting a single needle.
- Low-level laser therapy (LLLT) stimulates cellular mitochondria and sensory nerve endings at the same acupoints.
- This prompts a similar opioid-peptide response to traditional needling.
- For needle-sensitive patients, this photobiomodulation approach offers a technical, non-invasive alternative that still engages the body’s built-in pain-relief system.
Where Hijama Therapy Fits In
Combining Acupuncture and Hijama therapy (traditional cupping with controlled bloodletting) adds another layer to this mechanism.
- Hijama increases local microcirculation at the treatment site.
- It reduces inflammatory cytokines, which appears to complement the central nervous system’s endorphin release triggered by acupuncture.
- Together, the two modalities address pain from both a local, tissue-level angle and a central, neurochemical angle, one clearing inflammatory buildup, the other resetting the brain’s pain threshold.
The Bottom Line
Chronic pain affects huge numbers of people worldwide, often comes with other health problems, and is closely tied to social and economic factors like poverty and access to care. Because of this, pain should be treated as a major public health issue, not just a medical one.
This matters for policy too: simply focusing on making painkillers like opioids available isn’t enough. Real solutions need broader public health strategies that address prevention, care systems, and social conditions, not just medication access.
