Health insurance is like a kind of safety net you can have in case something bad happens to your health. It's like a protection plan that helps you if something unexpected or expensive happens with your health. Health insurance can help pay for doctor visits, hospital stays, tests and medicines that you need. It can also help pay for things like physical therapy or special equipment that might be necessary. Having health insurance can make it easier to pay for these things instead of having to pay for them out of your own pocket.
