Health refers to the overall state of an individual’s physical, mental, and social well-being. It encompasses the absence of disease or illness, as well as the presence of positive attributes that contribute to a person’s capacity to lead a fulfilling life. Health is often viewed through various dimensions, including physical health, which involves bodily functions and fitness; mental health, which pertains to emotional, psychological, and social well-being; and social health, which relates to the ability to form satisfying interpersonal relationships.
Health can be influenced by a wide range of factors, including genetics, lifestyle choices (such as diet, exercise, and sleep), environmental conditions, and access to healthcare services. Maintaining good health typically involves proactive measures such as regular medical check-ups, a balanced diet, regular physical activity, stress management, and avoiding harmful behaviors.
Public health focuses on promoting and protecting the health of populations through education, policy-making, and health services to prevent disease and improve health outcomes on a community or global scale. The World Health Organization (WHO) defines health as “a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity,” emphasizing that health is a holistic concept that transcends mere physical condition.
