Un estudio finlandés a largo plazo ha descubierto que los horarios de sueño inconsistentes durante la mediana edad pueden casi duplicar el riesgo de sufrir eventos cardiovasculares graves. Las personas que variaban mucho sus horas de sueño y pasaban menos de ocho horas en cama enfrentaban el mayor peligro.

Investigadores de la Universidad de Oulu siguieron a 3,231 personas nacidas en el norte de Finlandia en 1966. Registraron los patrones de sueño con monitores de actividad durante una semana cuando los participantes alcanzaron los 46 años y, posteriormente, realizaron un seguimiento de los resultados de salud a través de registros médicos durante más de diez años. Los eventos principales incluyeron ataques cardíacos y accidentes cerebrovasculares que requirieron atención hospitalaria.
