Not sure about the title. It appears to help you feel a bit better, but not cure the cold.

"The investigators found no difference in symptoms between the group that exercised and the one that rested. And there was no difference in the time it took to recover from the colds. But when the exercisers assessed their symptoms, Dr. Kaminsky said, 'people said they felt O.K. and, in some cases, they actually felt better.'"

Yeah. The entire message of the studies seems to be that colds don’t reduce your physical performance, and that exercise makes you feel better (I don’t think you necessarily need to be sick first for exercise to let you feel better…)

Very helpful, as I always get a cold when I start to exercise again, and end up giving it away.

Also, colds being a phenomenally successful disease, I wonder if not impairing the mobility of its victims is part of the reason? http://www.ted.com/index.php/talks/paul_ewald_asks_can_we_do... [video]

This sounds similar to the advice I've always heard: continue exercising if your symptoms are above your neck.
