Nearly everyone suffers from an occasional night of poor sleep. For many, that occasional problem can become persistent and bothersome and can cause us to struggle as we attempt to optimize our daily lives. Despite better insomnia classification and recent evidence-based clinical guidelines, some evidence suggests that current classification systems do not fully capture the range of subjective sleep complaints. Recent research has focused on evaluating existing treatments for patients with primary insomnia. With the growing evidence base for nonpharmacological interventions for insomnia, recent studies have also aimed to evaluate the efficacy of these interventions in a broader range of patient populations.
