Sneezing is actually good for you. Often, we feel embarrassed when we sneeze but stiffling it could have a negative impact on your health. According to experts, you are forcing air to travel at 100 miles per hour into your sinuses and eustachian tubes when you stifle a sneeze. If that trapped air is carrying germs and irritants, it can cause infections. A sneeze is the body's way of eliminating pollen, dust and other irritants. Suppressing it could also rupture an eardrum, causing pain, bleeding and in some extreme cases, permanent hearing loss. The next time you feel like sneezing, go ahead and sneeze. Just make sure you cover your mouth with a hanky so the irritants won't spread.
