Inversion There are many causes of back pain, including poor posture, weak back and stomach muscles, and misalignments to name a few. Many of these causes can actually be attributed to one force we must all battle: gravity. Inversion therapy puts gravity to work for you by placing your body in line with the downward force of gravity. Using your own body weight as a natural form of traction, inversion elongates the spine by increasing the space between the vertebrae, relieving the pressure on discs, ligaments and nerve roots. Less pressure means less back pain. By hanging upside down on an Inversion Table or inverted hanging frame you reverse the compression on your spine caused by gravity every time you sit, stand or walk. It also reduces back pain and rejuvenates the entire body, helping to relax your back so that the muscles stretch out from being constricted and tightened. Virtually every study ever done has shown a noticeable decrease in pain for the people using it. [People who have heart disease, high blood pressure, eye diseases (such as glaucoma), or are pregnant are at higher risk for the dangers related to inversion therapy and should consult their doctors about it first. Such people would have to progress very slowly, starting at very light levels of inversion. The first time anyone tries inversion therapy with gravity, they should be sure to have someone standing by, in case assistance is required to get out of the apparatus, or if health problems are experienced] [1] Wikipedia
