Food coma1 refers to the feeling of listlessness, bordering on sleep, that one feels after eating a large meal, often caused by a rush of blood to the stomach and intestines2 during food digestion3.
饭气攻心指的是在大吃一顿后感到的困倦,一般是由于在食物消化过程中血液很多涌向胃的原故。
Example:
I ate the whole pizza and now I'm slipping into a food coma.
我吃了一整张比萨,目前正渐渐进入饭气攻心状况。
