Diagnosis of Insomnia

A sleep medicine specialist may evaluate sleep patterns, medical history, and lifestyle factors to diagnose insomnia. Diagnostic tools may include:

  • Sleep diary – Recording sleep habits and disturbances over time.
  • Actigraphy – A wearable device that tracks sleep-wake patterns.
  • Sleep study (polysomnography) – An in-lab test that monitors brain activity, heart rate, breathing, and movements during sleep.

Treatment Options for Insomnia

Treatment depends on the severity and underlying cause of insomnia. Options may include:

Cognitive Behavioral Therapy for Insomnia (CBT-I)

CBT-I is a structured, evidence-based approach that helps address behaviors and thoughts interfering with sleep. It includes:

  • Sleep restriction therapy – Limiting time in bed to improve sleep efficiency.
  • Stimulus control therapy – Establishing a consistent sleep routine and limiting activities in bed.
  • Relaxation techniques – Breathing exercises and mindfulness strategies to reduce anxiety before bedtime.

Medications

Sometimes, sleep aids or medications may be prescribed for short-term relief. Options include:

  • Prescription sleep medications (used under medical supervision)
  • Over-the-counter sleep aids (short-term use only)
  • Melatonin supplements (to regulate sleep-wake cycles)

Lifestyle and Home Remedies

  • Maintain a consistent sleep schedule – Go to bed and wake up simultaneously each day.
  • Create a comfortable sleep environment – Keep the bedroom cool, dark, and quiet.
  • Limit screen time before bed – Reduce exposure to blue light from phones and tablets.
  • Avoid caffeine and heavy meals in the evening – These can disrupt the ability to fall asleep.
  • Incorporate relaxation techniques – Yoga, meditation, or deep breathing can help prepare the body for sleep.

When to Seek Medical Attention

If sleep disturbances persist for more than a few weeks or interfere with daily life, it’s crucial to seek medical attention. Aa sleep specialist can provide an evaluation and treatment plan. Chronic insomnia may require a combination of behavioral therapy, lifestyle changes, and medical interventions, and a specialist can guide you through this process.
