After you become used to being inverted at about 30 degrees, you can proceed to 60 degrees. Hanging upside down is healthy for your spine, as it allows gravity to gently pull and create traction. Traction is a process chiropractors perform to decompress their clients' spines and create space between the vertebrae. When a person lies on the inversion table and is two-thirds of the way upside down, gravity can naturally allow the spine to decompress, provided you relax your body. Inverted traction has been shown to be an "effective means of achieving pelvic traction at home," according to a study published in "Archives of Physical Medicine and Rehabilitation." As you're inverted, your vertebrae in the lumbar or lower region are pulled away from each other.
