Some social media habits may sound harmless, but a few can put your health at risk. One example is “vabbing,” a practice in which some women apply a small amount of vaginal fluid to areas like the neck, wrists, or behind the ears in hopes of attracting attention.

Supporters say it works through pheromones. Doctors note there is little evidence that this has the claimed effect in humans. Experts also point out that many everyday scents, such as soap, hair products, and perfume, would likely overpower any subtle body chemicals.

Health specialists warn that the bigger issue is safety. Collecting fluid with unclean hands can introduce bacteria and irritate delicate tissue. This may raise the risk of infections such as thrush or bacterial vaginosis. A gynecologist also cautioned that bacteria can sometimes travel upward in the reproductive tract and lead to pelvic inflammatory disease, which may cause scarring that can affect fertility.

Some people online encourage hygiene steps, like washing hands and avoiding the practice during illness or unusual symptoms. Even so, doctors stress the practice is medically unnecessary and carries avoidable risks.

If you are trying to feel confident or attractive, safer choices include clean skin, a fragrance you enjoy, and paying attention to any changes in discharge or odor that may need medical advice.
