Should You Exercise When You're Sick?

Should you skip a workout or two when you’re feeling under the weather?  It can be frustrating to miss a workout when you’ve been sticking to your New Year’s resolution!  I rarely miss a workout and find it difficult to know to say “no” to my exercise routine, but sometimes it’s necessary.  Assessing your symptoms can help you decide whether it’s a good idea to exercise or take a day off.

The general rule is if you have a cold affecting the neck and above you should be all right to exercise. However, it is probably best to work at a lower intensity.  Working out at higher intensities may slow down the healing process.  On the other hand if you have a fever, chest congestion, or body aches you should not work out at all.  These conditions are a sign the body is fighting illness and needs rest to promote healing.        

It is important to listen to your body.  This week I had a cold and while I felt okay performing every day activities, once I began my normal workout, I soon noticed I had much less energy and found it necessary to reduce the intensity and duration.  So instead of jogging or exercising on the elliptical, I walked on the treadmill.   

Missing a workout or two will not derail the progress you’ve made.  I have been guilty of teaching group fitness classes when I’ve been sick, thinking I could tough it out, but ended up missing more time than if I had rested for a day or two. Next time you’re sick assess your symptoms before heading out for your workout.  A brief time-out from your program may be the best decision.
