Insomnia

What is Insomnia?

Insomnia is a common sleep disorder characterized by persistent difficulty falling asleep, staying asleep, or waking too early — despite adequate opportunity and conditions for sleep. It can result in daytime impairment including fatigue, mood disturbance, difficulty concentrating, and reduced quality of life.

Insomnia is far more than an inconvenience. Chronic sleep disruption has profound effects on mental health, physical health, cognitive function, and emotional regulation. It is both a symptom of and a risk factor for conditions such as mood and anxiety disorders, making psychiatric assessment and treatment essential.

Types of Insomnia

Insomnia is classified based on duration and underlying factors:

  • Acute Insomnia: Short-term sleep disruption lasting days to weeks, often triggered by stress, life changes, or environmental factors.
  • Chronic Insomnia: Sleep difficulties occurring at least three nights per week for three months or more, often developing a self-perpetuating cycle.
  • Comorbid Insomnia: Insomnia occurring alongside other conditions like depression, anxiety, chronic pain, or substance use.
  • Paradoxical Insomnia: The perception of severe insomnia despite objective evidence of relatively normal sleep duration.

Common Insomnia Symptoms

Insomnia affects both nighttime experience and daytime functioning:

  • Sleep Onset Difficulty: Taking more than 30 minutes to fall asleep regularly, often due to racing thoughts or physical tension.
  • Sleep Maintenance Problems: Waking frequently during the night or for extended periods, with difficulty returning to sleep.
  • Daytime Impairment: Fatigue, irritability, difficulty concentrating, reduced motivation, and impaired performance at work or school.
  • Sleep Anxiety: Growing dread about bedtime, leading to a self-fulfilling cycle where worry about sleep itself prevents sleep.

Effective Treatment for Insomnia

Evidence-based insomnia treatment addresses both the symptoms and underlying causes:

  • CBT for Insomnia (CBT-I): The gold-standard treatment that addresses the thoughts, behaviors, and habits that perpetuate insomnia — and can be more effective than medication for successful long-term outcomes — is Cognitive Behavioral Therapy (CBT).
  • Sleep Hygiene Optimization: Establishing consistent sleep-wake schedules, optimizing the sleep environment, and eliminating habits that interfere with sleep.
  • Medication Management: When appropriate, short-term or targeted medication can break the insomnia cycle while behavioral changes take effect.
  • Treating Underlying Conditions: Addressing co-occurring depression, anxiety, or other psychiatric conditions that may be driving or maintaining insomnia.
