Can Acupuncture Help Stress?

According to the National Cancer Institute, acupuncture may cause physical responses in the brain, nerve cells, and pituitary gland.  The body's subsequent responses are to release proteins, hormones, and brain chemicals such as endorphins.  Endorphins work to reduce perception of pain in the opiate receptors of the brain.  It is believed that these body responses to acupuncture can then help to treat a variety of conditions such as stress.

Can Acupuncture Help Anxiety?

Acupuncture helps anxiety by offering a mental and physical release through the manipulation of various pressure points throughout the body. In acupuncture, tiny needles are inserted in the skin at predetermined areas to stimulate the nervous system. This stimulation actually relaxes the body and has a calming effect on the mind. Apart from anxiety, acupuncture can also be used to treat other common mental problems, such stress and depression. Physical issues that are symptoms, or causes, of anxiety such as insomnia and muscle tightness may also be helped by acupuncture.
