Hygiene Law and Legal Definition

Hygiene refers to a set of practices associated with keeping things clean in order to fight against illness and disease. The term hygiene is derived from the Greek word 'Hygeia', which means goddess of health, cleanliness and sanitation. It also refers to actions and practices that ensure health and healthy living. Though the term hygiene is most commonly associated with cleanliness, it is originally an old concept closely related to medicine, person and professional care practices. It can also refer to body hygiene, mental hygiene, domestic hygiene, dental hygiene, and occupational hygiene.

The term hygiene also refers to the name of a branch of science called hygienics that studies about health promotion and health preservation.
