How can such a small needle create such a significant response in the body?
One of the fascinating features of acupuncture is that it can provide substantial stimulation to deeper sensory nerves while causing relatively little tissue damage.
Needling can:
• Stimulate sensory nerves
• Release signaling molecules such as ATP
• Send signals to the spinal cord and brain
• Activate the body’s own pain-regulation systems
In other words:
Strong sensory stimulation
+
Relatively little tissue damage
This balance is one of the distinctive features of acupuncture.
And there is another important advantage:
No drugs are introduced into the body.
Compared with many medications, this means no drug–drug interactions and generally fewer systemic side effects.
Rather than simply suppressing pain from the outside, acupuncture may help engage the body’s own pain-regulation systems.
That’s what makes acupuncture so fascinating from a physiological perspective.
