What is asthma?

Asthma is when your lungs have trouble letting air in and out because they get blocked sometimes.

Imagine you're trying to blow out birthday candles, but someone put a big sponge inside your mouth, that’s what happens with asthma. Your lungs are like balloons, and sometimes they shrink or get filled with extra stuff that makes it hard for the air to pass through.

When you have asthma, your airways (the tubes that carry air into your lungs) can get tight, and they might also make more mucus, which is like extra slime inside your tubes. This makes it harder to breathe, kind of like trying to drink a thick smoothie through a straw.

Sometimes, things like dust, pollen, or even cold air can make the airways act up and feel blocked again. It's like when you put a lid on a jar that’s already half full, it doesn’t want to let more stuff in!

Asthma isn't always there, it comes and goes, just like your favorite toy might be missing one day but come back the next.
