Introduction: Prevalence of insomnia is higher in females and increases with higher age. Besides primary insomnia, comorbid sleep disorders are also common, accompanying different conditions. Considering the possible adverse effects of commonly used drugs to promote sleep, a nonpharmacologic approach should be preferred in most cases. Although generally considered first-line treatment, the nonpharmacologic approach is often underestimated by both patients and physicians. Objective: To provide primary care physicians an up-to-date approach to the nonpharmacologic treatment of insomnia. Methods: PubMed, Web of Science, and Scopus databases were searched for relevant articles about the nonpharmacologic treatment of insomnia up to December 2020. We restricted our search only to articles written in English. Main Message: Most patients presenting with sleep disorder symptoms can be effectively managed in the primary care setting. Primary care physicians may use pharmacologic and nonpharmacologic approaches, while the latter should be generally considered first-line treatment. A primary care physician may opt to refer the patient to a sleep medicine specialist for refractory cases. Conclusions: This paper provides an overview of current recommendations and up-to-date evidence for the nonpharmacologic treatment of insomnia. This article emphasizes the importance of cognitive-behavioral therapy for insomnia, likewise, exercise and relaxation techniques. Complementary and alternative approaches are also covered.
