An article by Daniel Seifert, published in National Geographic on 6 May 2026, explores what modern research is revealing about acupuncture and pain.
It describes the body’s built-in pain-relieving system, and how acupuncture may help engage it.
The article provides a useful springboard for thinking about pain more broadly. Many of the ideas it discusses have been developing within neuroscience over recent decades and are changing the way researchers think about pain, healing and sensory input in general.
The Brain's Role in Interpreting Pain
Pain is not simply a signal travelling from injured tissue to the brain. Nerves detect potentially harmful stimuli, but the brain has to interpret those signals before pain is consciously experienced. That interpretation is influenced by many factors including previous experiences, sleep, stress, attention, emotion, expectation and the responses of the people around us.
A child who falls over may barely react at first, then become distressed after seeing a parent’s alarm. Calm reassurance can completely change the experience. The injury has not changed in those few moments, but the brain’s interpretation of it has.
The same principle helps explain some otherwise surprising observations. Soldiers have sometimes continued functioning despite serious injuries until the immediate danger has passed, while phantom limb pain demonstrates that pain can persist even when the injured body part is no longer there. Chronic pain provides another example, where the nervous system may continue generating pain long after tissues have largely healed. Pain cannot always be understood simply by looking at the state of the tissues.
How the Body Regulates Pain
The nervous system also has its own ways of regulating pain. Signals travelling down from the brain can dampen incoming pain messages within the spinal cord before they reach conscious awareness, and the body is able to release its own pain-relieving chemicals, including endorphins and other naturally occurring opioids. Pain is therefore not simply something that happens to us. It is something the nervous system is continually regulating in response to the situation it finds itself in.
Acupuncture appears to interact with several of these existing systems. Research suggests that needling can stimulate nerve endings, influence local chemical signalling, affect immune activity, activate connective tissue responses and produce measurable changes in brain regions involved in pain processing. Rather than introducing something artificial into the body, it appears to encourage physiological processes that already exist.
What Happens When A Needle Meets Tissue
There is also growing interest in what happens mechanically when a needle enters tissue. Needling doesn’t simply puncture the skin. It produces small mechanical forces within the connective tissue that appear capable of triggering a cascade of neural, immune and biochemical responses. Researchers are still working to understand how these local effects contribute to the wider changes observed throughout the nervous system.
None of this means the picture is complete. Pain is one of the most complex experiences in medicine, and acupuncture is unlikely to have a single mechanism that explains every effect seen in research or clinical practice. Different conditions, different patients and different styles of treatment may involve different biological pathways acting together.
Perhaps the biggest shift over recent decades has been in pain science itself. The question is gradually moving away from, “How could a tiny needle possibly influence pain?” and towards, “How does a carefully targeted sensory stimulus interact with a nervous system that is constantly interpreting, regulating and adapting pain?” Once pain is understood as an active process rather than a simple read-out from damaged tissue, that becomes a much more interesting scientific question.
For anyone interested in exploring these ideas further, the National Geographic article is well worth reading:
