Answer 1

First the nerves and sensors in your nose feel something irritating. Then your take a slow but deep breath (so the irritant doesn’t go further inside your nose) to prepare a sneeze made to blow a lot of high pressure air to blow away the irritation. If you still feel the irritation and your lungs are full, you sneeze. If not, you just exhale.
