Social medicine is a way to help improve the health of entire communities. It looks at things like housing, education, and access to healthcare to figure out how to help people stay healthy together. For example, a social medicine team might make sure that everyone in a town has access to fresh fruits and vegetables, or that there are lots of parks and places to exercise. They might also make sure that there are enough doctors, nurses, and other medical workers to help people if they get sick. All of these things together can help everyone stay healthy!
