Our bodies are covered in about 1,000 different types of bacteria and about 80 kinds of fungi. Before you run for the shower this instant, keep in mind that many of those are good for you, helping you break down food and other necessary functions. However, if you don’t shower reqularly, this will leave room for the bad bacteria to win. Without showering, those bad bacteria will eventually find their way into your body through your mouth, nose, and even eyes. Now guess what? You’re sick.
