Eine neue App löst Schlafprobleme: Weil jede Person gut schlafen lernen kann. Das Leben ist oft hektisch und herausfordernd. Deshalb leidet etwa ein Viertel der Menschen in westlichen Ländern an schlechter bis sehr schlechter Schlafqualität – mit vielen negativen Folgen. Klinische Schlaflabors, wo aufwändige Messungen vorgenommen werden, haben aber lange Wartelisten. Um allen Menschen eine Schlafanalyse zu Hause zu ermöglichen, hat Prof. Manuel Schabus mit Mathematikern der Universität Salzburg eine neue Methode entwickelt, wie man nur aus der Herzaktivität, die in der Nacht mit einem einfachen Sensor gemessen wird, den Schlaf fast genauso präzise analysieren kann. Nukkuaa bietet dazu eine Schlaftherapie an, um den Schlaf langfristig zu verbessern.
