睡眠不足
You're Ravenous
变得贪吃
If you find yourself hungry all day （and not because you skipped breakfast or have recently amped up your gym routine）it might be because you've been skimping on sleep.
如果你发现自己特别容易饿（不是因为你不吃早餐或最近常去健身房），可能是因为你睡眠不足。
Research presented at the 2010 meeting of theSociety for the Study of Ingestive Behavior linked little shut eye with higher levels of the hormone ghrelin, the same one that triggers hunger, Huff Post reported.
据《赫芬顿邮报》报道，2010年，一份在摄食行为研究学会会议上做的研究报告表明，睡觉不足激素生成量更高，同样会触发饥饿感。
You Can't Shake That Cold
容易感冒
If you keep coming down with the sniffles -- orcan't seem to kick that never-ending case -- you might want to assess your sleep schedule. A 2009 study found that people who sleep fewer than seven hours each night have almost three times the risk of catching a cold than people whoslept for at least eight hours, the LA Times reported.
如果你总是鼻涕眼泪流个不停的状态，您可能就要评估一下你的睡眠时间表了。据《洛杉矶时报》2009年的一项研究发现，每晚睡眠不足七小时的人与至少睡八小时的人相比，患感冒的次数多出三次。
