Long nails are a major trend these days—seen on the hands of superstars like Cardi B and Billie Eilish. But a biologist warns this new trend may come with health hazards, considering what may be growing underneath.
Jeffrey Kaplan, a biology professor at American University, recently told USA Today that the area under the fingernail in the crevice is where most of the bacteria live.
“The longer the nail, the more surface area there is for microorganisms to adhere,” he said. “Studies have found 32 different bacteria and 28 different fungi underneath fingernails.”
Kaplan said it doesn’t matter if you have long artificial nails, long natural nails, gel nails, acrylic nails, or nail polish, because there is an increased probability of carrying microorganisms which makes it more difficult to decontaminate with handwashing or scrubbing.
One study found MRSA, an antibiotic-resistant bacteria that causes serious infections in hospitalized patients, underneath half of the fingernail samples collected, according to Kaplan.
Also, some of the bacteria under nails can be found on the skin, like staphylococcus, which can lead to an infection.
“You can transmit fingernail bacteria to your system by scratching, nail-biting, nose-picking, and finger-sucking,” Kaplan said.
He said the worst thing that could happen from the bacteria and fungi is a nail infection, which would not be life-threatening, but could leave your fingernails disfigured.
That is why most, if not all healthcare workers, are required to wear short nails due to being at risk for transmitting disease, according to Kaplan.
Two nurses at an Oklahoma City hospital may have contributed to the deaths of 16 babies in 1997 and 1998 because of bacteria found underneath their long nails, The New York Times reported.
Epidemiologists found a link between the deaths of the infants in the neonatal unit and the bacteria under the nails but did not prove it was the definite cause.
“When surgeons scrub for surgery and then they test their hands, there’s always bacteria under the fingernail and you can’t get rid of it,” Kaplan said.
Kayla Newman, a nail tech based in North Carolina, told USA Today that none of her clientele has had infections or “nasty nails” in her eight years of service. “Generally people who have long nails know how to maneuver with them and keep them clean,” she said. “If you’re spending upwards of $60 to get your nails done and you don’t keep them clean, that doesn’t make sense.”
Newman has seen the trend for long nails grow over the last couple of years and social media platforms, like Instagram and TikTok, showcase artistic designs on nails that can be over two inches long.
