If the sour stench of long since-dried sweat seems to pervade all your workout clothes, you're not alone (actually, there are quite a few embarrassing problems fit guys have); but you are in luck. Brand new research published in the Journal of Chromatography A reveals where the odor's coming from and how to eliminate it.
Why You Smell
First, you need to know the problem is only partially your fault. Your sweat is odorless until it mingles with bacteria—namely Corynebacterium and some Staphylococcus species—on your skin. When this happens, really nasty-smelling volatile organic compounds (VOCs) are created and nestle into the fibers of your clothes the researchers explain in a press release.
What's more, in light of protecting the environment, conserving resources, and reducing skin irritation, many people have turned to using fragrance-free detergents and keeping the water temperature during washing machine cycles cool. But this eco-friendly 68˚F cycle doesn't always do the trick.
