Most of us just worry about covering up our body odor, so we never let it linger enough to notice any changes in it. And since we know that body odor is pretty standard–anybody who doesn’t have it should, in fact, probably see a doctor–we don’t think it’s that weird if it’s a little different from one person to the other. But your body odor can also tell you a lot about your health. Your armpits are a hot spot for pheromone activity. In fact, some baby experts suggest that new moms rub their baby’s favorite toys on their armpits, to douse it in the comforting scent of their pheromones. So, with that in mind, your pits carry a lot of intel! Your sweat also carries plenty of information about what’s going on in your body. So even if you can’t stand the smell of your own body odor, take a second to pay attention to it–even if it’s just for a few seconds–each day so you can detect any changes. Here are things your body odor is telling you about your health.
