咬指甲是最容易感染的方式

Biting your nails is an easy habit to form and a hard habit to break. But no matter your reason for doing it, you really need to learn how to stop doing it, ASAP — according to experts, continuing to bite your fingernails is way riskier than you think. As Purvi Parikh, an allergy and infectious disease specialist with New York University's Langone Medical Center told The Cut, your fingernails can collect all sorts of nasties, from bacteria, dust, and dirt to debris, oils, and viruses. Yuck!

咬指甲是一個容易養(yǎng)成的習慣，也是一個很難改掉的習慣。但是，不管你為什么要這樣做，你真的需要盡快學會如何停止這樣做——根據(jù)專家的說法，繼續(xù)咬指甲的風險比你想象的要大得多。正如紐約大學朗根醫(yī)學中心的過敏和傳染病專家Purvi Parikh所說，你的指甲會收集各種各樣的臟東西，從細菌、灰塵、污垢到碎片、油污和病毒。天啊!

And if that's not enough to gross you out, maybe the fact that this all of this gunk can make you sick will. "Every time you touch your face — especially your mouth, nose, and eyes — you're transferring all of those germs. And you can get sick," Parikh explained, warning that biting your nails is, in fact, the easiest way to get an infection.

如果這還不足以讓你惡心的話，也許下面這一切會讓你惡心。帕里克解釋說：“每次你觸摸你的臉——特別是你的嘴、鼻子和眼睛——你都在轉(zhuǎn)移所有這些細菌。你可能會生病。”他警告說，事實上，咬指甲是最容易感染的方式。

Biting your nails can lead to nail damage and deformities

咬指甲會導致指甲損傷和畸形

On top of contracting infections, regularly biting your nails can also lead to nail deformation. "From chronic nail biting, you can damage the nail matrix (the tissue under the actual nail) and can have permanent nail deformities like ridges," New York City-based dermatologist Debra Jaliman told Health. You can even damage your teeth, whether they're your natural chompers or artificial ones. "Just as natural teeth can fracture from nail biting, porcelain veneers, and crowns can suffer the same fate," Gigi Meinecke, DMD, a Maryland-based dentist with the Academy of General Dentistry, told Health.

除了感染，經(jīng)常咬指甲也會導致指甲變形。紐約市皮膚科醫(yī)生黛布拉·賈利曼(Debra Jaliman)在接受《健康》雜志采訪時說：“長期咬指甲會破壞指甲基質(zhì)(實際指甲下的組織)，并可能導致永久性的指甲畸形，比如指甲隆起。”。咬指甲甚至會損壞你的牙齒，不管是天然的還是人為的。“正如原生牙齒可能因咬指甲而斷裂一樣，瓷貼面和牙冠也可能遭受同樣的命運，”馬里蘭州普通牙科學院牙科醫(yī)生Gigi Meinecke告訴《健康》雜志。

And there's even more bad news for nail biters who wear nail polish. According to Kristine Arthur, M.D., an internist at Orange Coast Memorial Medical Center in California, biting nails that have nail polish cause toxic poisoning. "Regular nail polishes have plenty of toxins themselves, but gel polishes have chemicals that are specifically approved only for topical use, meaning they're not meant to be ingested," she revealed.

對于涂指甲油的咬指甲者來說，還有更多的壞消息。加州橙海岸紀念醫(yī)學中心的內(nèi)科醫(yī)生克里斯汀·阿瑟醫(yī)學博士說，咬涂有指甲油的指甲會導致中毒。她透露：“普通指甲油本身含有大量毒素，但指甲油凝膠含有的化學物質(zhì)只被批準局部使用，這意味著它們不應該被攝入。”
