Eli5: Why sneezes so strong?
In: Biology
The purpose of sneezes and coughs are to remove obstructions in your airway. A cough is used to clear the lower part of your airway closer to your lungs and throat. When you cough, you can notice that it “rattles” lower in your throat. A sneeze on the other hand, is supposed to clear your upper airway which is the stuff in your nose. An obstruction can be anything or nothing really, but if the hair/nerves in your nose detect something, your lungs will inhale air, and then forcefully and suddenly expel it. The expulsion needs to be forceful enough to both reach your nostrils, as well as push any obstructions out of your nose
