You've just finished a big meal, and you're stuffed. You're thinking of taking a walk or even a stretch before clearing the table, but the thought of just getting out of your chair seems like a challenge. 

刚吃了一顿大餐，肚里饱饱的，正想着收拾桌子前散散步做做运动，但似乎困得都瘫在椅子上了。

The idea of taking a snooze on the couch seems more and more appealing. 

此时你越来越想在沙发上小睡一会儿。

Sounds familiar? There's a name for it: It's called postprandial somnolence -- commonly referred to as "food coma." The phenomenon refers to the tired, sleepy feeling that many of us experience after eating a big meal. 

听起来很熟悉？这就是餐后困倦，一般称为“食物昏迷”，指的是在大吃一顿后感到昏昏欲睡，我们很多人都有体会。
