Massage has many scientifically proven health benefits such as stimulating the blood and lymph systems, thereby increasing immunity and removal of toxins, stabilizing hormonal levels, and adding tone and flexibility to muscles -- all of which enhance the health of both you and your baby. As pregnancy progresses, your body adjusts to a changing alignment caused by the baby's increasing weight. This puts strain on your back and legs and increases stress on weight-bearing joints. Massage increases flexibility, enhancing the ability to carry this extra weight while also relieving aches and pains, leg cramps and muscle spasms. The effects of relaxation and tension release add to improvement in the physical state of muscles and joints, and assist in balancing emotions.
