Biotrauma

Biotrauma is what happens to our body when we breathe in things that are bad for us, like smoke or pollution. When we breathe in these bad things, our body tries to get rid of them by coughing or sneezing, but sometimes they can get stuck in our lungs.

When this happens, our lungs get irritated and inflamed, which can make it hard for us to breathe. It's like when we get a cold and our nose gets really stuffy, but it's happening in our lungs instead.

If we keep breathing in these bad things, it can make our biotrauma worse and even damage our lungs. That's why it's important to avoid breathing in things that can harm us and to keep our lungs healthy by exercising and eating healthy foods.
