Saúde é o nível de eficiência funcional ou metabólica de um organismo vivo. Em humanos, é a capacidade de indivíduos ou comunidades de se adaptarem e se autogerenciarem diante de desafios físicos, mentais ou sociais. A definição mais amplamente aceita de boa saúde é a da Constituição da Organização Mundial da Saúde. Afirma: “saúde é um estado de completo bem-estar físico, mental e social e não é meramente a ausência de doença ou enfermidade” (Organização Mundial da Saúde, 1946). Nos anos mais recentes, essa afirmação foi ampliada para incluir a capacidade de levar uma "vida social e economicamente produtiva". A definição da OMS não é isenta de críticas; principalmente que é muito amplo. Os aspectos mais sólidos do bem-estar que se encaixam firmemente no campo da medicina são saúde ambiental, nutrição, prevenção de doenças e saúde pública. Esses assuntos podem ser investigados detalhadamente e podem ajudar a medir o bem-estar. Por favor, veja nosso aviso médico para precauções sobre as limitações da Wikipédia.

Health – Health is a state of complete physical, mental and social well-being.
