Chronic fatigue syndrome, or CFS, is defined as unexplained fatigue that persists for longer than six months and gets in the way of normal functioning. Bed rest does not improve symptoms of CFS. Chronic fatigue sufferers may also have memory or concentration problems and tender muscles and joints. While physical activity can worsen chronic fatigue in some cases, being as active as possible is generally one of the best things you can do to feel better.
Considerations
Avoiding overexertion by striking a balance between rest and exercise is important for CFS patients. The majority of CFS patients who are able to engage in regular aerobic exercise report improved symptoms, according to the University of Maryland Medical Center, or UMMC. Exercise may be most helpful for people with CFS when it's performed in conjunction with counseling or cognitive behavioral therapy.
Recommendations
Gradually increasing the length and intensity of exercise may help diminish fatigue. Starting with five minutes or less of moderate exercise such as walking will help avoid overexertion. Extend your daily workouts a couple of minutes each day until you are exercising 30 minutes at a time, advises UMMC. Once you've hit the 30-minute mark, try to increase the intensity of your activity. For example, a leisurely stroll may become a brisk walk.
Exceptions/Limitations
It's unrealistic to assume that everyone with CFS can expect to follow a regular exercise and graded routine. Some patients may feel extreme fatigue after engaging in a little exercise while others may have more severe conditions that restrict physical activity, which may include being restricted to a wheelchair. CFS patients in general have a lower threshold for physical activity than healthy individuals, and over-exercising can worsen symptoms, cautions UMMC.
Outlook
Talk to your doctor about the appropriate balance between rest and exercise. Avoid too much physical activity on days when your energy level is especially low. Also be careful not to overexert yourself on days you feel good because that may only cause more bad days, cautions the Mayo Clinic. Keep in mind that setbacks are normal and expected. Try a variety of exercises until you find one that is comfortable and restorative. Many CFS patients have had good luck with tai chi and yoga, for example.
