Why Do We Get Hiccups?
我们为什么会打嗝？
-
Hiccups happen when the diaphragm muscle jerks suddenly.打嗝是由于膈肌突然抽动引起的。

This muscle helps us breathe in and out every day.这块肌肉每天帮助我们呼吸。

Irritation, fast eating, or drinking cold drinks can trigger it.刺激、进食过快或喝冷饮都可能引发打嗝。

The jerk closes the voice box quickly — 'hic!' sound follows.抽动会迅速关闭声门，随之发出‘嗝！’的声音。

Most hiccups last only a few minutes.大多数打嗝只持续几分钟。

Holding your breath or sipping water may help stop them.屏住呼吸或小口喝水可能有助于止嗝。
