People working in public health are working tirelessly to ensure that we have the best care possible, whether that be nutritious food, access to clean water, or the ability to go to the best healthcare facilities possible. However, many people don’t necessarily understand what public health is. Today, we’re going to talk about what public health is and why it’s important.

What is public health?

Public health is a wide variety of things. It can range from the scientific research conducted by scientists to the actual education of health itself. The people who are in the public health industry dedicate their lives to making sure that people are as healthy as possible. This can be encouraging people to vaccinate their children or get themselves vaccinated to stop the spread of disease, or even educating people around them about the harmful risks of substances such as alcohol and tobacco. These people also work with schools to develop nutrition programs to make sure that students there are getting accessibility to the healthiest foods, or even ensuring the safety standards so that workers in the industry are protected, 


Public health does things other than what was listed. They can help prevent diseases from breaking out, work to prevent injuries, and even help educate others on why some people are at a predisposition to suffering from health issues. These people advocate for laws that would make smoke-free indoor air and make seatbelts a necessity in cars and busses. These people want to find ways to stay healthy by giving us the best science-based solutions to our everyday problems.
