2. Sweet-smelling sweat
Sweat doesn’t smell great generally, but if it smells particularly bad, or at least worse than usual, there may be something up.
When you sweat you’re getting rid of toxins and chemicals within the body, so naturally there will be odor–but if it smells oddly sweet it could in fact be a bacterial infection on the skin or a yeast infection. Either of these can cause a sweet smell that you wouldn’t usually associate with sweat.
