There are more than 100 such points- the same points for both acupuncture and acupressure. Typically the points are pressed with one's fingers. The point on the wrist can also be pressed by wearing a wristband with a button to focus the pressure at the exact acupressure point. The wristbands are made specifically to press the anti-nausea acupoint. They provide continuing relief from the problem for many people.
Some people claim acupressure can effectively treat arthritis, obesity, and other problems.
Others say it can prevent illness by maintaining a proper balance among body organs and systems, although this is not a scientific idea. Studies show that acupressure does control pain and relieve nausea. Like acupuncture and some other hands-on therapies, acupressure may stimulate the release of endorphins, the body's natural pain killers. Exactly how it may work remains uncertain. Acupressure does not work for everyone, however.
