Health is a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity. Health may refer to the ability to adapt and manage physical, mental, spiritual, emotional, and social conditions through changes in lifestyle or self-care.
The word “health” is sometimes used as an abbreviation for “health care”, although health care is only one part of what is meant by health. For example, one might speak about the benefits of “going to the doctor” or “taking medicine”, or the costs of not getting enough sleep or exercise.
There are many other factors that impact on health each day: nutrition(the food we eat), childhood experiences (the way we were raised), quality of medical care (the drugs and surgery used), genetics (how strong our immune system is), stress levels (whether we feel anxious or depressed), environmental exposure to chemicals and toxins (pesticides on crops, exhaust from cars) and so on .
Health is a state of optimal physical, mental and social well-being, not merely the absence of disease or infirmity. An important way to promote health is to prevent disease, which can be accomplished through immunization programs and screening for early signs of disease. Promotion of good health often involves advice and education about healthy eating habits, exercise, hygiene, self-care, preventive measures against infectious diseases and other health practices. Health care systems are organizations established to meet the health needs of target populations.
