What practices focus on promoting good health and preventing disease through cleanliness?

Hygiene refers to the practices and habits that help maintain health and prevent the spread of diseases through cleanliness. This encompasses a range of activities, including hand washing, dental care, bathing, and handling food safely. By promoting cleanliness, hygiene helps to minimize the risk of infections and communicable diseases, making it a foundational aspect of overall health.

The other options, while related to health, focus on different areas. Nutrition emphasizes the importance of a balanced diet and the role of food in health, but it does not specifically address cleanliness. Exercise promotes physical fitness and overall well-being but is not directly correlated with disease prevention through cleanliness. Health education aims to provide individuals with knowledge about how to maintain their health and the importance of hygiene, among other topics, but hygiene itself is specifically about the practices of cleanliness. Thus, hygiene is the most direct answer regarding practices that promote good health through cleanliness.
