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.
