Health is the level of functional or metabolic efficiency of a living being. In humans, it is the general condition of a person's mind, body and spirit, usually meaning to be free from illness, injury or pain (as in "good health" or "healthy"). The World Health Organization (WHO) defined health in its broader sense in 1946 as "a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity." Although this definition has been subject to controversy, in particular as lacking operational value and because of the problem created by use of the word "complete", it remains the most enduring . Classification systems such as the WHO Family of International Classifications, including the International Classification of Functioning, Disability and Health (ICF) and the International Classification of Diseases (ICD), are commonly used to define and measure the components of health.
Systematic activities to prevent or cure health problems and promote good health in humans are undertaken by health care providers. Applications with regard to animal health are covered by the veterinary sciences. The term "healthy" is also widely used in the context of many types of non-living organizations and their impacts for the benefit of humans, such as in the sense of healthy communities, healthy cities or healthy environments. In addition to health care interventions and a person's surroundings, a number of other factors are known to influence the health status of individuals, including their background, lifestyle, and economic and social conditions; these are referred to as "determinants of health".

Famous quotes containing the word health:
“It is always singular, but encouraging, to meet with common sense in very old books, as the Heetopades of Veeshnoo Sarma; a playful wisdom which has eyes behind as well as before, and oversees itself. It asserts their health and independence of the experience of later times. This pledge of sanity cannot be spared in a book, that it sometimes pleasantly reflect upon itself.”
—Henry David Thoreau (1817–1862)
“The health of the soul is something we can be no more sure of than that of the body; and though a man may seem far from the passions, yet he is in as much danger of falling into them as one in a perfect state of health of having a fit of sickness.”
—François, Duc De La Rochefoucauld (1613–1680)
“To speak or do anything that shall concern mankind, one must speak and act as if well, or from that grain of health which he has left.”
—Henry David Thoreau (1817–1862)
