时差N小时 形成黑眼圈的几大原因(下)（在线收听）

What scientists do know is that the skin under the eyes is very thin and sensitive.

科学家们所知道的是，眼底的皮肤非常薄，非常敏感。

When for avariety of reasons blood and other fluids accumulate in the area under your eyes, the delicacy ofthe skin makes the fluid's color partly visible.

当由于种种原因，血液和其他液体在眼底部位积聚时，这层细腻的皮肤就会使得液体的颜色浮现出来。

This is what appears to account for the dark patches.

这似乎才是黑眼圈形成的原因。

Allergies may also be to blame.

过敏也是可能的原因之一。

And an allergic reaction can cause cells under the skin of the eyes torelease histamine, a chemical that causes fluid accumulation and swelling.

过敏反应导致眼底皮肤细胞释放出组胺，这种化学物质会引起积液和皮肤肿胀。

This is what appears tocause puffy eyes.

这似乎才是眼袋形成的原因。

And finally, there is heredity.

最后还有遗传因素的影响。

Do your parents have dark circles under their eyes?

你的父母是否有黑眼圈？

If so, you mayhave found the source for your own dark circles.

如果有，也许你就能够找到你有黑眼圈的原因。
