Hygiene includes cleanliness but goes beyond it by focusing on the scientific measures required to control pathogens and ensure a safe and healthy environment. For example, a person may wear clean clothes and appear neat, which reflects cleanliness. However, if that person does not wash hands with soap after using the toilet, they are not practicing proper hygiene, even though they look clean. Similarly, a floor may appear shiny and free from visible dirt, indicating cleanliness, but if it is not disinfected regularly in a hospital setting, harmful microorganisms may still be present. In this case, hygiene is lacking despite visible cleanliness. Another example can be seen in food preparation.
