Which definition best describes personal hygiene?

The definition that best describes personal hygiene is the daily maintenance of cleanliness by practicing good healthful habits. Personal hygiene encompasses a range of practices that individuals engage in to maintain their own health and wellbeing, which includes showering, brushing teeth, washing hands, and managing body odor. These habits are crucial not just for individual health but also for preventing the spread of illness and fostering a positive social environment.

Maintaining a tidy workspace, following a beauty regimen, and maintaining physical fitness are all important aspects of personal care and wellbeing but do not cover the broader concept of personal hygiene. A tidy workspace pertains to organization and cleanliness in a professional or personal environment. A beauty regimen typically involves cosmetic practices focused on appearance rather than hygiene. Maintaining physical fitness refers to exercise and physical health, which, while beneficial, does not directly relate to the practices of cleanliness and hygiene. Hence, the focus on daily practices directly aligns with the essence of personal hygiene, making it the most accurate choice among the options.
