Background & History
The concept of health has evolved across cultures and eras, rooted in ancient traditions like Ayurveda and traditional Chinese medicine. Modern definitions emerged during the 20th century, particularly with the establishment of the World Health Organization (WHO) in 1948, which defined health as "a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity." Key milestones include the development of preventive medicine, public health policies, and advancements in medical technology.
