When poor circulation occurs, poor healing of wounds and infections also occurs. That is why diabetics sometimes develop sores on the foot. Massage therapy for diabetics improves feeling (sensation) and circulation, so it can help prevent this common problem. With improved blood (and lymph) flow from therapeutic massage, the body is more able to fight infections in the body. Circulation is critical for good health. It is impaired in the diabetic. Massage improves circulation dramatically.
