Recent findings suggest that insomnia and emotion regulation are closely connected. Insomnia is widely associated with medical and psychiatric conditions as well as with impaired quality of life and emotional functioning. Additionally empirical evidence suggests that emotional dysregulation plays a crucial role in the onset and maintenance of psychopathological disorders. Although these seem to interact, very few studies investigated the relationship between disturbed sleep and problems in emotion regulation. Cognitive Behavioral Therapy for Insomnia (CBT-I) has been demonstrated to be effective in comorbid insomnia. However, emotion regulation skills are not included in this intervention. After reviewing the recent findings of the literature, we aim to discuss future directions for the inclusion of emotion regulation training in the treatment of insomnia disorder
