Health care refers to the maintenance and improvement of physical, mental, and emotional well-being through medical, nursing, and other allied health services. It includes preventive measures such as regular checkups and screenings, as well as treatment for illnesses and injuries.
Health care can be provided by a range of professionals including doctors, nurses, pharmacists, therapists, and other health care providers. It can be delivered in various settings such as hospitals, clinics, and primary care facilities.
Health care systems differ across the world, with some countries providing universal health care coverage for all citizens, while others rely on private insurance or out-of-pocket payments. The provision and availability of health care can have significant impacts on a population's overall health outcomes and quality of life.
