Needle This: Study Hints at How Acupuncture Works to Relieve Stress
By Dr. Mercola

Acupuncture, which has been valued as part of traditional Chinese medicine for thousands of years, is now used by millions of Americans each year, often to treat chronic pain. But now researchers have revealed the healing technique may also be effective in treating one of the most widespread ailments facing US adults: chronic stress.

Acupuncture May Relieve Chronic Stress

A new animal study showed that rats pre-treated with acupuncture had no spike in stress-associated hormones after being exposed to chronic stress.¹ On the contrary, rats that received no treatment or a sham acupuncture treatment had higher levels of corticotropin-releasing hormone (CRH) along with other stress hormones.  It is the constant increase in stress hormones that is associated with many of the health problems linked to chronic stress, such as depression, insomnia and anxiety. In stressed animals that received acupuncture, stress hormone levels were similar to those in the control animals that were not under chronic stress, which suggests the ancient healing modality helps to normalize stress hormone levels.  Interestingly, the acupuncture point used in the study was a point on the stomach, which may work by tapping into the gut-brain connection.  Research is now being carried out to determine if acupuncture is also effective at relieving stress when applied after the fact, as a treatment instead of a preventive strategy.

Acupuncture Also Confirmed to Help Treat Chronic Pain

In a recent analysis published in the Archives of Internal Medicine,² researchers concluded that acupuncture has a definite effect in reducing chronic pain, such as back pain and headaches – more so than standard pain treatment. Real acupuncture also produced slightly better results than using sham needles, which suggests the benefits of needling are due to more than the placebo effect.  

The study revealed a "clear and robust" effect of acupuncture in the treatment of:

• Back pain
• Neck pain
• Shoulder pain
• Osteoarthritis
• Headaches

On a scale of 0 to 100, participants who started out with a pain rating of 60 experienced:

• An average 30-point drop (a 50 percent reduction) in response to the real acupuncture treatments (using needles)
• A 25-point drop when receiving sham acupuncture
• A mere 17-point drop when receiving "standard pain care" that did not include acupuncture

One of the World’s Oldest Medical Practices

With documented use dating back more than 2,500 years, acupuncture is based on the premise that there are more than 2,000 acupuncture points in the human body, which are connected by bioenergetic pathways known as meridians. It is through these pathways that Qi, or energy, flows, and when the pathway is blocked the disruptions can lead to imbalances and chronic disease. 

The treatment itself, which involves the insertion of metallic hair-thin needles (typically three to 15) into specific acupuncture points, can be conducted by a physician or a trained acupuncturist. It generally involves little or no discomfort, and patients often report feeling energized or relaxed following the procedure. 

Acupuncture is proven to impact a number of chronic health conditions, and it’s thought that it stimulates the central nervous system to release natural chemicals that alter bodily systems, pain and other biological processes. Evidence, in fact, suggests that acupuncture impacts the body on multiple levels, including:³

• Stimulating the conduction of electromagnetic signals, which may release immune system cells or pain-killing chemicals
• Activation of your body’s natural opioid system, which may help reduce pain or induce sleep

• Stimulation of your hypothalamus and pituitary gland, which impact numerous body systems
• Change in the secretion of neurotransmitters and neurohormones, which may positively influence brain chemistry

WHO Reveals Dozens of Proven Uses for Acupuncture
