POPSUGAR: What is the lunula part of the nail?

POPSUGAR网站：指甲上的半月是什么？

Jin Soon Choi: The lunula is the light crescent marking on your nail where the nail emerges from the skin. It is part of the nail root, and most people have prominently visible lunula on their thumbnails and diminishing sizes to their pinky nails.

崔荣淑：在你的指甲从皮肤中新长出来的地方，就会有颜色很浅的半月标记。它是指甲根部的一部分，大多数人的大拇指指甲上都有明显的半月形，从大拇指甲到小指指甲的半月形逐渐缩小。

PS: What does it say about someone's health - both the lack of it or the presence of it?

补充：半月形能说明哪些健康状况呢——没有半月或者有半月形？

JSC: The presence of eight to 10 milky white lunula indicates good health if the lunula edge is sharp and clear. I believe in the ancient Chinese view of the lunula as the barometer of one's health and the modern medicine ideas with regard to specific conditions. The condition of the lunula really is an indication of your health. When your health declines, it is manifested in changes to the lunula, or the disappearance of it altogether. And when your health is restored, your lunula returns to its original condition.

崔荣淑：如果10个指甲中有8个乳白色月牙，而且月牙的边缘非常鲜明，那么说明你很健康。我相信古时候中国对于月牙看法，因为健康状况的晴雨表与现代医学中对于特殊状况的观点一致。月牙情况确实是可以反应健康状况。当你的体质下降，月牙的变化就会很明显，或者月牙完全消失。而且当你的健康恢复的时候，你的月牙也会恢复到原来的状况。

PS: Any advice on making your nails healthier in terms of diet or care?

补充：如何饮食或者注意些什么可以让你的指甲更加健康呢？

JSC: Diet is very important - eat dark green vegetables, fish oils, and nuts. Also be sure to stay hydrated, both orally and topically.

崔荣淑：饮食非常重要——吃一些深绿色蔬菜、鱼油和坚果。总而言之，还要保持体内水分充足。

PS: Anything else we should know about lunulas?

补充：对于月牙我们还应了解哪些呢？

JSC: Make sure your manicurist doesn't ruin your lunula when pushing back the cuticles. Pushing very hard on the lunula with a cuticle pusher can cause damage, which will be evident when the nail grows out.

崔荣淑：要确保美甲师在去除角质层的时候，不要伤害你的月牙。美甲角质推棒在月牙上非常用力的话，会损害月牙，尤其适当指甲再长出来的时候，就会非常明显。
