身体给你发出的健康讯号

　　COLD FEET: Poor circulation, right? Wrong. The blood vessels in our hands and feet tighten up when it’s chilly – which makes our fingers and toes cold and white. This is more noticeable in some people than others.

　　 BUT SEE THE DOC IF... you get an ache in your calves which comes on after you’ve walked a certain distance, particularly if you’re a smoker – that really could mean your blood vessels are clogging up.

　　脚部冰冷：是因为血液循环差吗？不是。天气冷时，人们手部和脚部的血管会收缩，使手指和脚趾冰冷、发白。这种情况在某些人的身上要更明显一些。

　　但如果有以下现象就要去看医生了……你在走了一段距离后，感到小腿疼痛——尤其是如果你是一个吸烟者——那可能真的说明你的血管堵塞了。
