Final answer:
The WHO definition of health encompasses a state of comprehensive well-being, including physical, mental, and social aspects, and is not limited to the absence of disease or infirmity. Health is relative, related to survival, reproduction, and social well-being, affected by a myriad of sociocultural factors.
Step-by-step explanation:
The World Health Organization's definition of health describes a state of complete physical, mental, and social well-being, not merely the absence of disease and infirmity. This expansive definition acknowledges that health is a multifaceted concept. Health is not just the absence of biological abnormalities, which can be categorized as 'disease', but also includes mental and social aspects. Our understanding of health goes beyond biomedicine, accommodating the complexities of human wellness, including factors like dietary trends that recognize wellness as a state of optimal well-being, not just the lack of sickness. Additionally, the concept of social health reveals the interconnectedness of physical, mental, and social wellness, indicating that a faltering in one can influence the others.
Overall, health can be understood as a relative state wherein a human is capable not only of surviving but thriving, enjoying life, and fulfilling both individual and social roles effectively. Ensuring survival, successful reproduction, procuring sustenance, and participating in social networks are all part of being considered healthy. Health involves complex interplay involving physiological, behavioral, and sociocultural factors, integral for an individual's well-being.
