We’ve all been there—that sudden urge to sneeze in a quiet meeting or crowded elevator, and the instinct to hold it in takes over. However, have you ever wondered what really happens when you stifle a sneeze?

Before you clamp down the next time your nose tingles, let’s look at the surprising science behind sneezes and why letting them out might just be the safest choice for your health.

According to the Health publication, holding in a sneeze can cause damage to the eyes or nose, potentially causing a superficial ruptured blood vessel, causing a red eye or subconjunctival haemorrhage.

It is further stated that this can also lead to an ear infection, as the eustachian tube connecting the nose to the middle ear may push allergens back, causing an infection.

“You control where that misdirected pressure goes in your body, which could then affect what unsuspecting and undeserving body part ruptures, fractures, or breaks. The stifled sneeze also shifts around your body depending on where the pressure valve is.”

The Cleveland Clinic mentions that suppressing a sneeze can cause mucus and irritants to return to the sinuses, potentially causing sinus pain, congestion, and infections.

The above clinic provides safer ways to avoid sneezing, stating that to reduce sneezing, you must avoid triggers like allergens or strong odours, change your environment, use nasal sprays, and antihistamines, stay hydrated, and use a humidifier.

These methods are beloved to help reduce irritation and sneezing by moisturising nasal passages and blocking histamine release. Additionally, staying hydrated and using a humidifier can also help alleviate dryness. “Deep breathing exercises or techniques like pursed-lip breathing, taking slow deep breaths or even humming can help calm your body’s response to irritants and reduce the urge to sneeze.”
