The relationship between anxiety, sleep, and cognitive performance is complex and mutually reinforcing. Anxiety heightens physiological arousal, interfering with the ability to achieve restorative sleep. Inadequate sleep subsequently impairs cognitive domains such as attention, executive function, and working memory.
