This always seems to be a question that I get from clients and is a prevalent situation for many during the winter months. I myself just was sick for about a week and had to really think about my condition and to note how my body felt. There were a few days that I felt fine getting a light workout in but other days I could barely walk without aches and pains in my muscles. It's best to take care of our bodies and give it what it needs.
Here are some suggestions from Dr. Edward R. Laskowski at the Mayo Clinic.
Mild to moderate physical activity is usually OK if you have a standard cold and no fever. Exercise may even help you feel better by opening your nasal passages and temporarily relieving nasal congestion.
As a general guide for exercise and illness, consider this:
Exercise is usually OK if your symptoms are all "above the neck." These signs and symptoms include those you may have with a common cold, such as runny nose, nasal congestion, sneezing or minor sore throat.
Consider reducing the intensity and length of your workout. Instead of going for a run, take a walk, for example.
- Don't exercise if your signs and symptoms are "below the neck," such as chest congestion, hacking cough or upset stomach.
- Don't exercise if you have a fever, fatigue or widespread muscle aches.
Let your body be your guide. If you have a cold and feel miserable, take a break. Scaling back or taking a few days off from exercise when you're sick shouldn't affect your performance. Resume your normal workout routine gradually as you begin to feel better. And check with your doctor if you aren't sure if it's OK to exercise.
Remember, if you do choose to exercise when you're sick, then reduce the intensity and length of your workout. If you attempt to exercise at your normal intensity when you have more than a simple cold, you could risk more serious injury or illness.
