Holding back a sneeze can cause a brain aneurysm, throat rupture, or lung collapse in rare cases. This was reported by Speech.
Sneezing is a protective reflex aimed at removing irritants from the nose. However, the pressure in the airways is 30 times greater than the pressure during vigorous physical activity. According to doctors, the speed of air propagation during sneezing varies between 5 m/s and 150 km/h.
You can stop sneezing by pinching your nose, pulling your ear, or lifting your tongue to the roof of your mouth. All these methods aim to stimulate the trigeminal nerve, which is responsible for the sneezing reflex. However, covering your mouth or nose when sneezing increases airway pressure 5 to 20 times more than free sneezing. Without outlet, this pressure can damage eyes, ears, or blood vessels. Although the risk is low, brain aneurysms, throat ruptures and lung collapse have been reported due to holding in a sneeze.
The Conversation concludes, therefore, that it is best to try to prevent the sneeze reflex by treating allergies or eliminating irritants, or simply sneezing into a tissue.
