What process involves both physical and mental wellness?

Health maintenance encompasses both physical and mental wellness, making it the correct answer. This concept focuses on the various strategies and practices that individuals engage in to preserve and improve their overall health. Health maintenance includes regular physical activity, balanced nutrition, routine medical check-ups, and mental health practices such as stress management and mindfulness.

Engaging in health maintenance means promoting a holistic approach to well-being, which recognizes that mental and physical health are interconnected. For instance, routine exercise not only boosts physical fitness but also releases endorphins that enhance mood and alleviate stress, thus benefiting mental health as well.

The other options, while related to aspects of health, do not fully encapsulate the concept of integrating both physical and mental wellness. Cleansing typically refers to the removal of toxins and may not address mental health. Recovery usually focuses on the process of returning to a previous state of health, particularly after illness or injury, without a definitive emphasis on maintaining wellness. Hygiene primarily pertains to practices that prevent disease through cleanliness, lacking the broader perspective of overall wellness that health maintenance includes.
