Sleep in Adults: Insomnia

Sleep insufficiency, insomnia, and related sleep disorders are concerns that affect millions of US adults. The disorders also contribute to significant cognitive, emotional, and physical health challenges. Insomnia affects approximately 30% of the US population. It is characterized by difficulty falling asleep, difficulty staying asleep, and early-morning waking and is linked to daytime distress and impairment. Common sleep disruptors include environmental factors such as noise, light, and air pollution and also personal habits such as excessive screen use before bedtime. Evaluating patients with insomnia in primary care requires integrating sleep health assessments into routine visits and use of insomnia screening tools and sleep diaries for accurate diagnosis. Nonpharmacologic therapies such as sleep hygiene and cognitive behavior therapy for insomnia are the preferred treatments. Pharmacotherapy or combination therapy (with cognitive behavior therapy for insomnia and pharmacotherapy) may be considered when these interventions are ineffective. Family physicians should weigh the risks and benefits of insomnia medication use carefully for all patients but especially for older adults because of potential adverse effects. Managing insomnia effectively in primary care involves a comprehensive approach, prioritizing nonpharmacologic strategies, regular monitoring, and patient-centered care.
