Definition
Insomnia is characterized by difficulty initiating or maintaining sleep, or early morning awakenings, with daytime impairment despite adequate opportunity for sleep.
Pathophysiology
- Hyperarousal model: elevated cognitive and physiological arousal (HPA axis activation, sympathetic tone) sustains wakefulness.
- Conditioning: bed becomes associated with wakefulness through maladaptive behaviors.
Diagnosis
- Clinical diagnosis using standardized scales (ISI, PSQI) and sleep diary; rule out circadian disorders, restless legs, apnea, pain, and medication effects.
Treatment
- First‑line: CBT‑I components — stimulus control, sleep restriction, cognitive restructuring, relaxation, sleep hygiene.
- Adjuncts: short‑term pharmacotherapy when necessary; cautious, evidence‑based use of melatonin or doxepin.
Prevention
- Consistent sleep schedule, wind‑down routine, morning light exposure, limit caffeine after midday, and device curfew 1 h before bed.

Real-Life Example: Sophia’s Natural Sleep Journey
Sophia, a 34-year-old teacher, struggled with falling asleep after stressful days. She avoided screens for an hour before bed, drank chamomile tea, and practiced a 10-minute meditation routine. She also used a sleep tracking app to monitor her REM and deep sleep stages. Within a few weeks, Sophia reported falling asleep faster, experiencing fewer night awakenings, and waking up refreshed.
