"By lying down with your head lower than your feet you can improve cerebral circulation and Increase lymphatic flow in the lower extremities.
After years of living upright, gravity can take its toll on your body. We develop poor cerebral circulation and edema in our legs and feet. Our skin and organs begin to sag and prolapse, restricting proper functions.
The slant board is a great way to return good blood flow to the brain. This can also help our internal organs, relieving some of the pressure that gravity puts on them." Robert Morse, N.D. from his book "The Detox Miracle Sourcebook".
