L’ottimismo fa bene alla salute e questa volta lo conferma anche la scienza. I rischi di morte per qualsiasi causa risultano inferiori del 30% tra le persone che "pensano positivo" (anche di fronte alle difficoltà) rispetto a chi è più propenso a vedere nero.
Uno studio di lunga durata, pubblicato sull’American Journal of Epidemiology e realizzato dalla Harvard University su un campione di 70'000 infermiere, identifica per la prima volta anche i diversi rischi di mortalità a seconda delle malattie.
Le più ottimiste hanno una probabilità di morire per infezioni più bassa del 52% rispetto alle pessimiste, ma anche un rischio inferiore di morte per ictus (-39%), infarto o malattie polmonari (-38%).
