My Stomach Makes a Funny Sound Sometimes
我的肚子有时候会发出奇怪的声音
-
Hiccups happen when your diaphragm — the muscle below your lungs — contracts suddenly.
-
This quick jerk pulls air into your throat and slams your vocal cords shut with a 'hic' sound.
-
Eating too fast, drinking fizzy drinks, or feeling nervous can all trigger hiccups.
-
Most hiccups last only a few minutes and go away without any treatment needed.
-
Holding your breath or sipping cold water may help calm the diaphragm again.
-
Babies hiccup often because their nervous systems are still learning to control breathing.
-
Doctors rarely worry about short hiccups, but long ones might need gentle tests.
-
You can talk, walk, or laugh while hiccuping — it won’t hurt your body or voice.
-
Some people try sugar on the tongue or gentle neck pressure to stop stubborn hiccups.
-
Even astronauts get hiccups in space — gravity isn’t the main cause of this funny reflex.
