Health is a multidimensional state of complete physical, mental, and social well-being, influenced by factors like genetics, environment, society, and lifestyle, according to the WHO. Maslow's hierarchy of needs proposes that basic physiological needs must be met before safety, love, esteem, and self-actualization needs, with fulfillment of lower needs motivating progress to higher needs. Dimensions of health include physical, emotional, intellectual, environmental, sociocultural, spiritual, and occupational factors.
