Many hormonal changes affect the nervous system, including some that act on specific areas of the brain that control pleasure and elation. The circulation to that muscle increases, the muscle becomes stronger and more shapely, the connective tissue becomes stronger, and the muscle-nerve interaction improves. Improved physique, grace, balance, and posture result. The body s second circulation system, the lymphatic system, is an important part of its defense against disease and toxins. Movement of the lymphatic fluid toward the heart is partially dependent on muscular compression of the lymphatic vessels.
Exercise is an excellent stress reducer.
Stress manifests itself in the form of muscular tension and hormonal imbalances. Exercise releases the tension in muscles and stimulates the hormonal system. Exercise is a much more effective deterrent to stress than drugs or alcohol. All this combined with the improved posture and coordination affects your natural body language.
