Not everyone perspires equally: some sweat profusely, while others barely notice it even during intense workouts. Body odor varies too—for many, sweat remains nearly scentless, but for others, it's a persistent issue. The real cause? Armpit bacteria that metabolize odorless sweat into smelly compounds. Deodorants and antiperspirants have long been our go-to solutions. Now, U.S. researchers reveal a surprising breakthrough: bacteria from others' sweat could neutralize bad odors effectively.
Researchers tested this on twin pairs, one with strong body odor and the other without. They transplanted bacteria from the low-odor twin's sweat into the affected twin's armpit. Astonishingly, the odor disappeared—like magic. The team tracked results for over a year across multiple twin sets, confirming lasting effects. They're now refining a "universal" bacterial version to benefit everyone, bypassing the idea of using someone else's sweat directly.
