What encompasses physical health and well-being?

Physical health and well-being involves the efficient functioning of all body systems, which is essential for carrying out everyday tasks effectively. This comprehensive approach recognizes that physical health is not just about the absence of illness or disease, but also about how well the body operates as a whole. When all body systems, including the muscular, cardiovascular, and respiratory systems, work harmoniously, individuals can engage in physical activities, maintain energy levels, and perform daily chores without undue fatigue or difficulty.

While aspects like exercise and nutrition are important components of maintaining good physical health, simply having "a little exercise and good diet" does not necessarily cover the broader concept of physical well-being. Mental wellness is a distinct aspect that contributes to overall health but does not encapsulate the entirety of physical health, which requires both physiological and functional aspects to be considered. Thus, focusing solely on the absence of illness fails to address the dynamic nature of physical well-being where active body systems contribute to a person's ability to thrive in daily life.
