There is a lot that can be left up to personal preference when it comes to cutting one’s nails, but if you want to ensure you don’t get stuck in a unhealthy situation, board-certified podiatrist Nelya Lobkova, DPM, and licensed physician Leann Poston, MD, recommend cutting your fingernails every week. On the other hand, Esteban Kosak, MD, a medical doctor and researcher with Symptoms Care, says you go could go as far as waiting every few weeks to cut them—but waiting comes with heightened health risks.ae0fcc31ae342fd3a1346ebb1f342fcb “When you don’t cut your nails often, they can easily get damaged and break, and are more likely to harbor dirt and bacteria that can potentially spread infection,” Kosak explains. According to Lobkova, fingernails grow an average of 4 millimeters per month, and Poston says that your “dominant hand’s nails will grow faster than your non-dominant hand.” However, your toenails actually grow at a slower pace—about 2 millimeters per month, according Lobkova. Toenails, therefore, can be trimmed less often, but still need maintenance every few weeks. “You are more prone to skin infections such as cellulitis and fungal skin infections if the toenails are not trimmed regularly,” says Bruce Pinker, DPM, a foot specialist and owner of Progressive Foot Care. “Also, if you don’t cut your toenails often enough, it can be difficult to walk, as the toenails will grow around the toe, leading to pain and discomfort.” But it’s not just how often you trim your nails—it’s also how you’re doing it. Poston says you should use your personal nail clippers and “cut your nails so they are even with the ends of your fingers or toes.” Avoid rounding off the edges of your nails when cutting because you’re “more likely to get ingrown toenails as the edge of the nail pushes into the skin.” As it turns out, cutting your nails regularly may not only help you steer clear from skin or nail health problems. Lobkova says the “nails on our fingers and toes could demonstrate a pattern that is a sign of disease or other abnormalities in the joints, bones, skin, and major organs.” So regularly checking your nails and seeing if there are any changes or difficulty in cutting them can help determine if there may be any underlying health concerns at play.
