Hygiene is a series of practices performed to preserve health. According to the World Health Organization (WHO), "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. Good personal hygiene is essential in today's society for both health and social reasons. Keeping your hands and body clean is vital in stopping the development and spread of illness and infection. This simple habit doesn't just benefit your health – it can help protect those around you too. Basic hygiene in the workplace can be put down to four different things: personal hygiene; work area cleanliness; clean restroom facilities; and a clean kitchen.
