Stopped cold: Exercising when sick
Wednesday, December 31st, 2008
Even if you take precautions, you’re bound to catch at least one cold this winter. But a cold doesn’t necessarily mean you have to take off time from your workout regimen.
Some fitness experts (and non-experts) say it depends on “where” the cold strikes your body. If the cold symptoms are above your neck, you can go ahead and exercise. If the symptoms are below the neck (i.e., in your chest), you should take some time off. But does science back this up?
A recent New York Times article reported that the question of whether it’s okay to work out with a cold—and, if so, at what intensity—”stumps many exercise physiologists and infectious disease specialists.” The question hasn’t received much attention from researchers.
The Times found only two studies that addressed this issue, both conducted at Ball State University a decade ago. The first study found that “having a cold had no effect on either lung function or exercise capacity,” even though the participants reported feeling fatigued.
The second study considered whether exercising with a cold affects your symptoms and recovery time. (As part of this study, “researchers collected the subjects’ used facial tissues, weighing them to assess their cold symptoms.” Yuck.) The researchers found no difference in symptoms or in the time it took to recover from the colds between cold sufferers who exercised and those who rested. And when the exercisers assessed their symptoms, some said they felt okay and others actually felt better.
As a result, the Ball State researchers “encourage people to exercise when they have colds, at least if they have the type producing symptoms like runny noses and sneezing.” They’re more cautious about colds that produce fevers or symptoms below the neck, like chest congestion. They find that some patients are suspicious when advised they can continue exercising—these patients want to back off of their efforts a bit. In response, one expert offers this warning:
“… that’s O.K. if it’s for a short period of time. But what you have to be cautious of, where I see it as more of an issue, is with people who are trying to build that exercise habit. They’ve got all these barriers anyway.”
In other words, don’t let a cold derail your fitness program.
