What are dilation of airways?

Dilation of airways means the tubes we use to breathe get bigger, like when a tunnel gets wider so more cars can pass through.

Imagine you're blowing up a balloon, that's your lungs. The airways are like the straw you use to blow it up. When they dilate, it's as if the straw becomes wider, making it easier for air to go in and out.

When your airways dilate, it’s like when you're playing with a slide, imagine the slide gets smoother and wider, so you can zoom down faster. That’s how breathing feels easier when the airways get bigger.

Sometimes, when you have a cold or asthma, your airways feel tight and narrow, like a straw that's been squished. But when they dilate, it’s as if someone gives that straw a good stretch, suddenly, breathing becomes easier again.

So dilation of airways is just a fancy way of saying the tubes we use to breathe get bigger, helping us take deeper breaths and feel better.
