This article provides sound reasoning as to why exercise is an important aspect of coping with CFS.
“Most of us with FMS and/or ME/CFS have been unable to maintain a regular exercise program. The problem is that with Fibromyalgia, lack of exercise can increase our pain levels while too much exercise or exercise done incorrectly can also increase our pain and fatigue.
In the case of Chronic Fatigue Syndrome or ME, as the body becomes deconditioned, the CFS worsens and as the CFS gets worse, it becomes more difficult to exercise leading to further deconditioning. The autonomic nervous system that is already not functioning well in ME/CFS becomes even more problematic with lack of tone in the legs and lower body. This lack of tone allows blood to pool and upon standing the blood does not get pumped back up to the brain efficiently. This can cause dizziness and faintness immediately upon standing, but can also cause problems as long as 15-20 minutes later. Exercise strengthens the lower legs and abdomen and doesn’t allow as much “space” for blood to pool and therefore prevents some of the dizziness and weakness that we may experience.”
