But should you work out when you obviously have the cold?
There is surprisingly little research in this area to help doctors make recommendations, but two little know studies from long ago support the theory that exercise can be beneficial to people suffering from the cold.
According to the Mew York Times:
" The studies began, said Leonard Kaminsky, an exercise physiologist at Ball State University, when a trainer at the university, Thomas Weidner, wondered what he should tell athletes when they got colds.
The first question was: Does a cold affect your ability to exercise? To address that, the researchers recruited 24 men and 21 women ages 18 to 29 and of varying levels of fitness who agreed to be deliberately infected with a rhinovirus, which is responsible for about a third of all colds. Another group of 10 young men and women served as controls; they were not infected.
At the start of the study, the investigators tested all of the subjects, assessing their lung functions and exercise capacity. Then a cold virus was dropped into the noses of 45 of the subjects, and all caught head colds. Two days later, when their cold symptoms were at their worst, the subjects exercised by running on treadmills at moderate and intense levels. The researchers reported that having a cold had no effect on either lung function or exercise capacity.
“I was surprised their lung function wasn’t impaired,” Dr. Kaminsky said. “I was surprised their overall exercise performance wasn’t impaired, even though they were reporting feeling fatigued.”
He said he also tested the subjects at different points in the exercise sessions, from moderate to intense effort, and found that their colds had no effect on their metabolic responses."
