Inversion therapy involves being upside down or at an inverted angle while hanging by the legs, ankles, or feet with the intention of therapeutic benefits. The process of doing so is called inversion. It is a form of spinal decompression and is a form of spinal traction. Gravity boots are ankle supports designed for inversion therapy. Some people use gravity boots to add an extra challenge to workouts, doing inverted crunches or squats.
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. 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.
During an episode of acid reflux, small amounts of stomach acid may manage to escape from the stomach and into the oesophagus. Typically, gravity minimises this upward leakage but combining an inversion table and acid reflux can be a painful, nauseating, and potentially dangerous combination.
