Editorial: Psychological Sleep Studies: New Insights to Support and Integrate Clinical Practice Within the Healthcare System

Adequate sleep is essential for good health, physical functioning, cognitive performance, and self-regulatory processes. In contrast, sleep disorders affect multiple aspects of an individual’s life, including daytime activity, social interactions, mood, and quality of life, playing a role in the whole healthcare public system. Consistently, sleep disorders, especially insomnia, have been reported to be key risk factors for mental and somatic disorders. The International Classification of Sleep Disorders (ICSD-3rd edition, American Academy of Sleep Medicine, 2014) includes six main clinical divisions: Insomnia, Sleep Related Breathing Disorders, Central Disorders of Hypersomnolence, Circadian Rhythm Sleep-Wake Disorders, Parasomnias, and Sleep Related Movement Disorders. Currently clinical practice is often lacking of systematic consideration of psychological aspects related to sleep disorders.
