What is health?

Definition of health

Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.

Definition of Physical Health

Physical health is defined as the condition of your body, taking into consideration everything from the absence of disease to fitness level.

Physical health is critical for overall well-being, and can be affected by:

Lifestyle: diet, level of physical activity, and behavior (for instance, smoking);
Human biology: a person’s genetics and physiology may make it easier or harder to achieve good physical health;
Environment: our surroundings and exposure to factors such as sunlight or toxic substances;
Healthcare service: good healthcare can help prevent illness, as well as detect and treat illness.

Definition of mental health

Mental health is an integral and essential component of health. The WHO constitution states: "Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity." An important implication of this definition is that mental health is more than just the absence of mental disorders or disabilities
