A hiccup is a muscle contraction.
If I were to test your reflexes with a rubber mallet on your knee, it would cause a muscle contraction, wouldn’t it?
Okay, what it you had already contracted that muscle, and lifted your leg? There’s nothing to contract now. No “reflex” if I strike your knee with the rubber mallet.
Your hiccup is a reflex.
Which muscles contract when you hiccup?
The same muscles you use when you swallow and hold your breath.
Why do most hiccup cures involve eating, drinking, holding your breath, or swallowing?
Because sometimes doing those things works, because you contract your swallowing muscles at the right time.
But why do they not always work?
Because if you relax those muscles, the reflex can still happen.
So here’s the tricky part:
Swallowing, but holding those muscles, not relaxing them. It takes a bit of concentration and conscious effort.
Swallow, but don’t complete the motion fully. Concentrate and hold those muscles tight as long as you can.
When the reflex comes, your muscles will already be contracted, releasing you from the cycle of hiccups.
It may take some practice- most people don’t know how to swallow and hold it. It’s not something you normally do. I’m not talking about swallowing and then holding your breath. I’m talking about holding your throat at mid-swallow. That’s tough. I won’t lie, it can be difficult.
However, you physically cannot hiccup if you do it correctly.
Learn how to do this and you will never have the hiccups again. I never have more than 1 or 2 hiccups before I self-correct. I have taught many folks about this and it works, but some people it takes longer because they have trouble mid-swallowing.
