Halotherapy is a way to help people breathe easier by using salt. Imagine you are playing in the sandbox and you get some sand in your nose. Your nose feels itchy and you might sneeze. That is what happens when you breathe in salt. But with halotherapy, the salt is treated so it is super clean and safe to breathe in. You might go to a special room with salt on the walls and floor. You sit there for a while, and as you breathe in the air, it can help clean out your nose and lungs. It can be like taking a really big deep breath of fresh air at the beach!
