Luz nocturna durante el sueño eleva riesgo cardiovascular

Investigadores de la Universidad Tulane en Nueva Orleans informaron que la exposición a luz de bajo nivel durante el sueño se asoció con una mayor incidencia de insuficiencia cardíaca, fibrilación auricular, infarto, accidente cerebrovascular y mortalidad cardiovascular. Estudios previos con más de 11 000 participantes habían demostrado que dormir en entornos con una iluminación superior a 3 lux provocaba el engrosamiento de la pared del ventrículo izquierdo y una reducción de la función cardíaca, lo que sugiere que la luz nocturna es un factor de riesgo cardiovascular modificable.
