Exercise helps to keep us in good health. Doctors at the American Heart Association suggest getting at least 150 minutes of proper physical activity every week. Many people exercise for a few minutes every day or every other day. So, getting 150 minutes every week is easy.
But what about those times when you are sick? If you do not feel well, should you keep following your exercise habit? Following are the answers from health experts.
Edward R. Laskowski is a doctor at the Mayo Clinic. He and other experts have a general rule about exercising when you are sick. It is usually fine to exercise properly (not hard), he explains, if your symptoms are all “above the neck”. These signs may include a runny nose, sneezing or a sore throat.
Geralyn Coopersmith, a physical fitness trainer who has written several books on exercise offers similar advice. However, both Coopersmith and Dr. Laskowski suggest taking a break from exercising if signs of your illness appears “below the neck”. Pay special attention to symptoms such as chest congestion, bad cough or pain in the stomach.
There are other symptoms that can tell you to avoid exercise. They include a higher than normal body temperature, a sense of feeling very tired, and widespread muscle pain.
Both Coopersmith and Dr. Laskowski suggest listening to your body. If you feel really bad, take a break and let your body rest. If you don’t feel too bad, these experts both suggest cutting down the amount of exercise. For example, if you usually run, take a quick walk instead.
