means The practices of cleanliness and self-care that prevent disease and maintain health.

from From Greek 'hygieinos,' meaning healthful, rooted in 'Hygieia,' the goddess of health herself — daughter of Asclepius, the god of medicine. The ancient Greeks literally deified the concept, which tells you how seriously they took not getting sick. The word entered English via French in roughly the 17th-18th century, originally tied to the whole art of preserving health rather than just scrubbing your hands.
