When you sneeze do stop breathing for a second?
When you sneeze, you expel air forcefully through your nose and mouth. This happens because the muscles in your chest and abdomen contract, creating a build-up of air pressure in your lungs. When the pressure reaches a certain point, it's released through your mouth and nose.
During a sneeze, the diaphragm (the muscle that separates your chest and abdomen) contracts very quickly. This creates a strong positive pressure in the lungs, which is then quickly released when the vocal cords open. The resulting high-velocity airstream causes the expelled air to move through the nose and mouth at speeds of up to 100 mph.
In order to sneeze, you need to breathe in first to bring air into your lungs. So although when you sneeze is it like a mini explosive breath but you would need to breath first or be unable to sneeze.
