Fingernails Grow Faster Than Toenails

Are you trying to grow your nails? 

你有想长指甲的想法吗?

Nails may refer to fingernails or toenails. Fortunately, fingernails grow three to four times faster than toenails. Unfortunately, toenails are much thicker than fingernails. 

指甲可能指的是手指甲或脚趾甲。幸运的是,指甲的生长速度是脚趾甲的三到四倍。不幸的是,脚趾甲比手指甲要厚得多。

Fingernails can break, split, or bend quite easily. Did you know that the nails on your dominant hand grow more quickly? This is handy, since these nails are more likely to wear down from use. Nails are made of keratin, a protein that is also found in hair and skin. Long, strong nails in children are a sign of good health. Fingernail growth slows down after puberty. This can be a nail-biting time for teens. People who bite their nails often get hangnails. Hangnails are not really nails. A hangnail is a flap of torn skin at the root of the nail. Hangnails on toes are usually caused by dry skin.

手指甲很容易折断、裂开或弯曲。你知道你惯用手的指甲长得更快吗?这很有用,因为这些指甲在使用过程中更容易磨损。指甲由角蛋白组成,这种蛋白质也存在于头发和皮肤中。长而结实的指甲是孩子身体健康的标志。青春期后,指甲的生长缓慢。对青少年来说,这可能是一个紧张的时刻。咬指甲的人经常会有指甲倒刺。倒刺并不是真正的指甲。倒刺指的是指甲根部撕裂的皮肤。脚趾上的倒刺通常是由皮肤干燥引起的。
