How Does Acupuncture work from Johns Hopkins Library.

​

Conduction of electromagnetic signals.

Evidence suggests that acupuncture points are strategic conductors of electromagnetic signals. Stimulating these points enables electromagnetic signals to be relayed at greater-than-normal rates. These signals may start the flow of pain-killing biochemicals, such as endorphins, or release immune system cells to specific body sites.


Activation of the body's natural opioid system. Considerable research supports the claim that acupuncture releases opioids, synthetic or naturally-occurring chemicals in the brain that may reduce pain or induce sleep. These chemicals may explain acupuncture's pain-relieving effects.

Stimulation of the hypothalamus and the pituitary gland. Joined at the base of the brain, the hypothalamus and pituitary glands are responsible for many body functions. The hypothalamus activates and controls part of the nervous system, the endocrine processes, and many bodily functions, such as sleep, regulation of temperature, and appetite. The pituitary gland supplies some of the body's needed hormones. Stimulation of these glands can result in a broad spectrum of effects on various body systems.

Change in the secretion of neurotransmitters and neurohormones. Studies suggest that acupuncture may alter brain chemistry in a positive way. This is accomplished by changing the release of neurotransmitters (biochemical substances that stimulate or inhibit nerve impulses) and neurohormones (naturally-occurring chemical substances that can change the structure or function, or impact the activity of, a body organ).
