晚上睡不好会让你想吃垃圾食品

A bad night’s sleep makes us crave junk food, a study has found.

一项研究发现，晚上睡不好会让我们想吃垃圾食品。

It sharpens our sense of smell, making us hone in on greasy grub such as burgers, chips and doughnuts. The findings were published in eLife.

它能增强我们的嗅觉，使我们更喜欢油腻的食物，如汉堡、薯条和甜甜圈。研究结果发表在《eLife》杂志上。

Sleep deprivation increases hormones called endocannabinoids, which have been linked to the “munchies.”

睡眠不足会增加一种叫做内源性大麻素的激素的分泌，这种激素与饥饿感有关。

They make eating more enjoyable — but also increase the desire for specific types of foods such as biscuits, cakes and chips.

他们使吃东西更愉快，但也增加了对特定类型食物的渴望，如饼干、蛋糕和薯条。

Thorsten Kahnt, who led the study at Northwestern University, said: “It might be worth taking a detour to avoid your local doughnut shop next time you catch a 6 am flight.”

美国西北大学(Northwestern University)领导这项研究的托尔斯滕·卡尔特(Thorsten Kahnt)说:“下次你赶上早上6点的航班时，不妨绕道避开当地的甜甜圈店。”

“When you’re sleep-deprived these brain areas may not be getting enough information. You’re overcompensating by choosing food with a richer energy signal.”

“当你睡眠不足时，这些大脑区域可能得不到足够的信息。当你选择了能量信号更丰富的食物，这是过度补偿。”
