Insomnia is a common sleep disorder characterized by persistent difficulties in falling asleep, staying asleep, or waking up too early and being unable to return to sleep. Despite having adequate time and opportunity for rest, individuals with insomnia often feel unrefreshed upon waking. It’s important to note that insomnia is not considered a disease itself, but rather a symptom of other underlying issues.
People suffering from insomnia often experience daytime consequences such as fatigue, irritability, mood swings, difficulty concentrating, and reduced performance in daily tasks.
Types of Insomnia
Insomnia is generally categorized based on its duration and root cause:
-
Acute Insomnia: Short-term and typically triggered by stress, life changes, or a specific event. It usually lasts a few days or weeks.
-
Chronic Insomnia: Long-lasting (occurring at least three nights per week for three months or longer) and often linked to underlying health or psychological issues.

Treatment for Insomnia
Effective treatment depends on the cause and severity. Options include both non-medication and medication-based therapies:
1. Sleep Hygiene
Improving sleep habits and creating a sleep-friendly environment:
-
Keep a consistent sleep schedule
-
Avoid screens before bedtime

Make the bedroom dark, quiet, and cool

Cognitive restructuring

Butisol (butabarbital)
-
Triazolam
Note: These medications should be used only under a doctor’s guidance and are typically reserved for short-term use due to potential dependency and side effects.

5. Lifestyle Modifications
-
Regular physical activity (avoid exercising too close to bedtime)
-
Limiting naps during the day

Practice good sleep hygiene
-
Address stress and emotional health proactively
-
Seek professional help when needed
CBT-I remains the most effective long-term treatment, while medications may provide short-term relief. Consultation with a doctor or sleep specialist is vital for accurate diagnosis and personalized treatment planning.
