Understanding the Sneeze Reflex
Before diving into the tricks, it's helpful to understand what causes a sneeze. A sneeze is a powerful, involuntary reflex action designed to expel irritants from your nose. This process is controlled by the trigeminal nerve, a large cranial nerve responsible for sensation in the face. When an irritant like dust, pollen, or pepper enters the nasal passages, it stimulates the nerve endings, which send a message to the brainstem. Once a certain threshold is met, the brain triggers the reflex, leading to the explosive burst of air we know as a sneeze.
Pressure Point Techniques
Some of the most effective tricks for stopping a sneeze involve stimulating specific pressure points on your face to distract or interrupt the trigeminal nerve signal. Catching the sensation early is key for these methods to work.
The Upper Lip Press
One widely cited method involves applying firm pressure to your upper lip with your index finger, just beneath your nose and against your gums. This sends a competing signal to the trigeminal nerve, effectively distracting the brain and rerouting the neurological message that initiates the sneeze. The pressure should be firm, almost to the point of mild discomfort, and held for several seconds until the sensation fades.
The Nasal Bridge Pinch
Another trick is to pinch the soft part of your nose just below the bridge, using your thumb and index finger. This method can also be used by gently squeezing the very top of your nose, near the inner corner of your eyebrows. The goal is to stimulate the nerves in that area to distract from the impending sneeze signal.
Tongue to Palate Pressure
For a more subtle approach, try pressing your tongue firmly against the roof of your mouth. Focus the pressure on the spot just behind your two front teeth. Hold this pressure for 5–10 seconds. The intense sensation created by your tongue can help override the sneeze reflex signal before it becomes unstoppable.
Distraction and Environmental Adjustments
Sometimes, simply distracting yourself or altering your immediate environment can be enough to prevent a sneeze.
-
Look at a Bright Light (Photic Sneezing): Interestingly, for some people (estimated to be 18–35% of the population), looking at a bright light can trigger a sneeze. If you feel a sneeze coming on due to other irritants, intentionally looking away from a bright light source might help. If you have the photic sneeze reflex, however, this trick would have the opposite effect.
-
Blow Your Nose: If an irritant is the cause of the tickle, blowing your nose can often clear the foreign particles and eliminate the need to sneeze altogether. This is one of the safest and most direct methods for prevention.
-
Adjust Your Environment: Pay attention to your triggers. If you have allergies, using an air purifier, wearing sunglasses on sunny days, or avoiding known irritants can be highly effective at preventing sneezes.
Comparison of Sneezing Prevention Methods
To help decide which method might work best for you, here is a comparison table of common sneeze-stopping techniques:
| Technique | How it Works | Effectiveness | Discretion | Important Caveat |
|---|---|---|---|---|
| Upper Lip Press | Distracts the trigeminal nerve via competing pressure signal. | High, if caught early. | Low-to-Moderate (looks like you're thinking). | Avoids the risk of holding in the sneeze. |
| Nasal Bridge Pinch | Overloads local nerve endings to interrupt the sneeze signal. | High, if caught early. | Moderate (visible action). | Effective, but can feel unusual. |
| Tongue to Palate Press | Distracts the trigeminal nerve with pressure on the roof of the mouth. | High, if caught early. | High (can be done discreetly). | Requires firm, sustained pressure to be effective. |
| Look Away from Light | Avoids the photic sneeze reflex trigger. | Only for individuals with this specific reflex. | High. | Not a universal solution for all sneeze triggers. |
| Blow Your Nose | Removes the irritant directly. | High, if an irritant is the cause. | Low (requires a tissue and public action). | Very safe, but may not be possible in all situations. |
The Dangers of Forcibly Holding a Sneeze
While the tricks mentioned above are relatively safe, it is crucial to understand the risks of suppressing a sneeze by pinching your nose and closing your mouth simultaneously. This action traps the immense pressure generated by the sneeze, which can be 5 to 24 times greater than a normal sneeze, and forces it back into your body.
This redirected pressure can potentially cause serious damage, although such cases are rare. Reported risks include:
- Ruptured Eardrum: Pressure forced up the Eustachian tube into the middle ear can damage the eardrum and cause hearing loss.
- Throat and Diaphragm Damage: In rare instances, the pressure can cause a throat rupture or damage the diaphragm, leading to a collapsed lung.
- Damaged Blood Vessels: Tiny, fragile blood vessels in the eyes or nose can burst, causing visible hemorrhaging.
- Brain Aneurysm Rupture: In very rare cases, extreme pressure could potentially cause a pre-existing, weak brain aneurysm to rupture.

Conclusion: Practice Safe Sneezing
Learning a few quick tricks to stop a sneeze can be useful in certain situations. The most reliable methods focus on distracting or overriding the nerve signal before the sneeze fully develops. However, if the urge is too strong, it is always safer to let the sneeze happen. The proper etiquette is to sneeze into a tissue or the crook of your elbow to prevent the spread of germs, protecting both yourself and others. Never hold in a sneeze by pinching your nose and closing your mouth, as the risks outweigh the temporary social awkwardness.
