Functional medical approach and nutrition therapy for primary insomnia

Abstract

Primary insomnia, a common disorder encountered in primary care settings, exhibits a global incidence of 15%-30%. While many cases resolve naturally, some remain for a long time and recur frequently. This chronicity can decrease the patients' quality of life, leading to various health problems, increased medical costs, and societal burdens. Cognitive behavior therapy is a primary therapy for insomnia, but its use remains limited. Consequently, both physicians and patients rely on pharmacological interventions. However, concerns persist due to the lack of established consensus for optimal prescription of sleep medications, especially regarding dependency and misuse risks. The authors review the functional medicinal approach and nutritional therapy for primary insomnia, for in aiding conventional medical treatment.
