Exercise has benefits for every body system; it is effective both as a treatment and for prevention of disease. It can improve memory and concentration, lessen sleep disorders, aid heart disease by lowering cholesterol and reducing blood pressure, help sexual problems such as erectile dysfunction, and raise low libido. Exercise does it all.
Even with cancer, particularly colon and recurrent breast cancer, the data show clearly that exercise is a deterrent. Newer studies on a glycoprotein called Interleukin 6 suggests that general body inflammation, a factor in almost every chronic disease, is reduced by regular exercise.
