Answer:
Hygiene is a series of practices performed to preserve health.
According to the World Health Organization, "Hygiene refers to conditions and practices that help to maintain health and prevent the spread of diseases." Personal hygiene refers to maintaining the body's cleanliness.
Many people equate hygiene with 'cleanliness,' but hygiene is a broad term. It includes such personal habit choices as how frequently to take a shower or bath, wash hands, trim fingernails, wash clothes, and basically self care. It also includes attention to keeping surfaces in the home and workplace, including bathroom facilities, clean and pathogen-free. Many people know without taking care of your teeth the food would leave many bacteria and without flossing it, it can lead to the food between your teeth to get bad causing a cavity, then tooth decay.
Good luck.
