What is an important aspect of good hygiene?

Good hygiene is fundamentally centered around personal cleanliness. This aspect plays a crucial role in promoting health and preventing the spread of illness. Maintaining personal cleanliness involves practices such as bathing regularly, brushing teeth, washing hands, and taking care of one's nails and hair. These habits not only contribute to individual health but also foster a pleasant environment for oneself and others, making it a key component of overall well-being.

While aspects such as a regular eating schedule, having a circle of friends, and routine physical exams are important for health and social well-being, they do not directly pertain to hygiene practices. Personal cleanliness specifically addresses the actions and behaviors involved in maintaining one’s body and preventing infections, which is why it is the most relevant choice in this context.
