指甲为什么容易断裂

When someone complains about a broken nail, it hints that the person isn't used to working with their hands.

当有人抱怨指甲断了，往往意味着这个人不习惯用手工作。

That being said, a broken fingernail can mean a lot of things. Rather than being a sign that someone doesn't work with their hands, it could be a sign that they work with their hands too much. Mechanics aren't known for having long, luxurious nails buffed to a soft finish, and it's all too easy to crack a knuckle — let alone a nail — when you're working with an engine.

话虽如此，断指甲有很多含义。与其说这是某人不用手工作的标志，不如说这是他们用手工作太多的标志。众所周知，汽车修理工的指甲可不是长而豪华的，，当你在修理发动机时，关节都很容易弄断，更不用说指甲了。

As WebMD says, brittle and easily broken nails can be a sign that someone's hands are regularly moving between wet and dry. One example is someone who works in the medical or hospitality field. Moisture makes our nails swell, and when they dry, they shrink again. Going through this process over and over can leave nails brittle and prone to breaks. Wearing gloves can help stop the cycle, but only if that is the cause of a person's brittle nails. In some cases, the cause runs much deeper.

正如WebMD所说，指甲易碎且容易折断可能是一种迹象，表明某人的手经常干湿间往复。比如在医疗或酒店业工作的人。水分使我们的指甲膨胀，干燥时，又会收缩。反复进行这个过程会使指甲变脆，并且容易折断。戴手套有助于阻止恶性循环，但前提是这就是你指甲脆裂的原因。在某些情况下，原因要复杂的多。

When harsh chemicals and frequent wet-dry cycles are ruled out, brittle nails can be blamed on nutrients and blood not reaching the fingertips. WebMD explains that both poor nutrition and certain medical issues, like Raynaud's Syndrome, can limit the nutrients and blood flow that reaches a person's nails. Anemia, another possible cause, can limit the amount of oxygen in a person's bloodstream, which also leads to brittle nails (via Penn Medicine).

当严酷的化学物质和频繁的干湿循环被排除在外后，脆弱的指甲可能被归咎于营养物质和血液没有到达指尖。WebMD解释说，营养不良和某些医学问题，如雷诺综合征，都会限制到达指甲的营养和血液流动。贫血是另一种潜在因素，它会限制人血液中的氧气量，也会导致指甲脆裂。

These are serious conditions, and if someone is experiencing additional symptoms, they should speak to a healthcare provider. However, there is one more common reason for brittle nails, one that affects most people, regardless of their health. Aging, as it turns out, is hands-down the most common reason that a person's nails become brittle. MedlinePlus states that as we age, our nails may become brittle, and the ends may become prone to breaking. Other changes include thickening toenails and an increased risk of ingrown nails.

这些情况都很严重，如果有人出现其他症状，他们应该咨询医疗人员。然而，指甲变脆还有一个更常见的原因，也是影响到大多数人的原因，且与他们的健康状况无关。事实证明，衰老是指甲变脆的最常见原因。MedlinePlus指出，随着年龄的增长，我们的指甲可能会变得脆弱，指甲末端可能会断裂。其他变化包括脚趾甲增厚和指甲向内生长的风险增加。
