Full Definition
Sleep onset insomnia is a specific type of insomnia characterized by persistent difficulty falling asleep within a reasonable timeframe, typically defined as taking more than 30 minutes to fall asleep on most nights. This condition can be caused by various factors including anxiety, poor sleep hygiene, circadian rhythm disorders, medical conditions, or medications. Patients often report lying awake feeling frustrated and watching the clock, which can worsen the problem through performance anxiety. Treatment approaches include cognitive behavioral therapy for insomnia, sleep hygiene education, relaxation techniques, and sometimes short-term sleep medications.
