Imagine your nose is like a little tunnel where air goes in and out. Sometimes, this tunnel can get blocked because of tiny things like boogers or swollen blood vessels.
A nasal decongestant is like a superhero spray. When you use it, it tells those swollen blood vessels to shrink, just like when a balloon gets smaller. This makes more space in your nose tunnel for air to flow freely, and that helps you breathe better! So, it’s like a magic spray that helps your nose feel better and not stuffy anymore.
