Yes, it is bad to close your mouth when you sneeze.
Why You Shouldn't Hold in a Sneeze
When you sneeze, your body is trying to expel irritants from your nose and throat forcefully. Trying to suppress this natural reaction, especially by closing your mouth, can lead to several issues. According to research, closing your mouth or nose during a sneeze dramatically increases the pressure in the airways five to 20 times more than a normal sneeze.
Potential Risks of Holding Back a Sneeze:
- Damage to Eyes: The increased pressure can affect the delicate structures of your eyes.
- Damage to Ears: The pressure can potentially rupture your eardrum or cause other ear-related issues.
- Damage to Blood Vessels: The forceful pressure can cause damage to blood vessels, although rare.
When you allow a sneeze to happen naturally, the pressure is released outward. However, if you block that path, the pressure has to go somewhere, potentially causing internal harm. Therefore, it's best to sneeze freely (covering your nose and mouth with a tissue, your sleeve or bent elbow) and not try to hold it in.
How to Sneeze Safely:
- Use a tissue to cover your mouth and nose when you feel a sneeze coming.
- If you don't have a tissue, sneeze into your elbow or upper arm.
- Wash your hands thoroughly after sneezing.
In conclusion, sneezing with your mouth open is a natural, beneficial process, while holding it in is detrimental. Let the sneeze do its job and use proper hygiene afterward.
