Insomnia

Definition of Insomnia

  • Insomnia: habitual sleeplessness; inability to sleep.

    • A common sleep disorder characterized by persistent difficulty falling asleep, staying asleep, or waking up too early and struggling to return to sleep.

Signs and Symptoms of Insomnia

  • Difficulty falling asleep or staying asleep: Individuals may find it challenging to initiate sleep or may wake frequently during the night.

  • Waking up too early: Patients often wake earlier than desired and cannot return to sleep.

  • Feeling unrefreshed after sleep: Even after a full night in bed, individuals may not feel rested.

  • Daytime fatigue: This includes feelings of tiredness throughout the day, irritability, difficulty concentrating, and changes in mood.

  • Reduced performance: Insomnia can lead to a decline in work or school performance due to fatigue and cognitive impairments.

Causes of Insomnia

  • Mental Health/Stress: High levels of stress from work, anxiety, depression, trauma, or grief can contribute significantly to insomnia.

  • Lifestyle/Habits: Poor sleep hygiene, such as irregular sleep schedules, excessive screen time, caffeine and alcohol consumption, and insufficient physical exercise.

  • Medical Conditions: Chronic conditions like pain, acid reflux, asthma, thyroid problems, and neurological disorders may impede sleep.

  • Medications: Certain medications, including antidepressants, stimulants, cold/allergy medications, and high blood pressure drugs, can interfere with sleep.

Treatment of Insomnia

  • Cognitive Behavioral Therapy for Insomnia (CBT-I):

    • Go to bed only when sleepy to strengthen the association between bed and sleep.

    • Use the bed exclusively for sleep; avoid activities like reading, working, or watching TV in bed.

    • The 20-Minute Rule: If awake for more than 20 minutes (or feeling frustrated/anxious), get out of bed, go to another room, and engage in a relaxing, quiet activity (e.g., reading, listening to soft music) until feeling sleepy again, then return to bed.

  • Sleep Hygiene Improvements:

    • Maintain a consistent sleep schedule.

  • Lifestyle Changes:

    • Limit intake of caffeine and alcohol.

  • Medication:

    • Sleep medications may be prescribed but should only be used temporarily as they are not ideal for long-term management.
