From cold water to lemon slices, simple techniques can interrupt the reflex behind hiccups, but persistent cases may signal deeper health issues.
Hiccups are a small but irritating diaphragm spasm that produces the familiar “hic” sound. They happen when the diaphragm, the muscle separating the chest and abdomen, contracts involuntarily, causing a sudden intake of air followed by reflex closure of the vocal cords.
The result is a rhythmic, often annoying sound most people experience occasionally, according to Research Gate.
While hiccups usually pass quickly, a variety of home remedies exist to interrupt the nerve reflex responsible for them. Some have physiological explanations, while others remain anecdotal but are surprisingly effective for many people.
Why Hiccups Happen
Hiccups occur due to irritation or disruption in the nerve pathways connecting the brain and diaphragm, particularly the phrenic and vagus nerves.
When these nerves are stimulated, the diaphragm contracts suddenly and uncontrollably.
Common triggers include:
The characteristic sound happens when the vocal cords close abruptly to stop additional air from entering the lungs.
Types of Hiccups by Duration
Hiccups are generally harmless, but their duration can indicate different causes:
- Temporary hiccups – Last seconds or minutes, and usually resolve without treatment.
- Persistent hiccups – Continue longer than 48 hours but less than a month.
- Chronic hiccups – Last over one month and typically require medical evaluation.
- Recurrent hiccups – Occur repeatedly in episodes lasting several minutes.
Hiccups lasting more than 48 hours may indicate underlying medical conditions and should be assessed by a doctor.
Ten Practical Ways to Stop Hiccups
Medical research on hiccup remedies is limited, so many recommended techniques rely on clinical experience rather than controlled trials.
Still, several methods aim to stimulate the vagus nerve or reset breathing patterns.
1. Hold Your Breath
Increasing carbon dioxide levels in the lungs may relax the diaphragm. Take a deep breath, hold it for 10–20 seconds, then exhale slowly. Repeat if necessary.
2. Breathe Into a Paper Bag
Slow breathing into a paper bag can alter oxygen-carbon dioxide balance and help stop spasms. Never use plastic bags due to suffocation risk.
3. Gargle With Cold Water
Cold water stimulation at the back of the throat may interrupt the hiccup reflex through vagus nerve activation.
4. Pull Knees to Chest
This posture gently compresses the diaphragm and may reset the nerve signals causing spasms.
5. Stimulate the Roof of the Mouth
Gently brushing the palate with a toothbrush or cotton swab can activate nerve responses linked to hiccups.
6. Sip Cold Water or Suck Ice

Small, slow sips of cold water or sucking ice cubes may stimulate nerves enough to interrupt hiccups.
7. Eat Something Sour or Sweet
Lemon slices, sometimes with salt, or a teaspoon of sugar, may stimulate sensory nerves that override the hiccup reflex.
8. Sudden Startle
A surprise reaction can disrupt nerve signaling, though it is not always practical to induce.
9. Perform the Valsalva Maneuver
Take a deep breath, pinch your nose, close your mouth, and gently exhale against resistance for about 10–15 seconds. This can stimulate the vagus nerve.
10. Distract Your Mind
Counting backward, reciting something complex, or focusing intensely on a mental task may indirectly calm the reflex.
When Hiccups May Signal a Problem

Most hiccups disappear quickly without treatment. However, persistent episodes lasting more than two days can indicate underlying health conditions.
Potential causes include:
Medical procedures involving anesthesia can also trigger prolonged hiccups in some patients.
Bottom Line
Hiccups are usually harmless diaphragm spasms that resolve on their own, but simple physical or sensory techniques can often stop them faster.
Persistent hiccups lasting more than 48 hours deserve medical evaluation, as they can sometimes reflect underlying health issues rather than a minor annoyance.
