• Acute Insomnia: Lasts for a short period, typically less than 3 months, and is often caused by stress, travel, or changes in sleep environment.
• Chronic Insomnia: Lasts for more than 3 months and can be caused by a variety of factors, including underlying medical conditions, lifestyle habits, and psychological issues.
• Onset Insomnia: Begins suddenly, often in response to a specific event or stressor.
• Maintenance Insomnia: Characterized by difficulty staying asleep throughout the night.

Causes of Insomnia

• Stress and Anxiety: Ongoing stress and anxiety can make it difficult to fall asleep and stay asleep.
• Poor Sleep Habits: Irregular sleep schedules, consuming caffeine or nicotine before bedtime, and engaging in stimulating activities before bed can disrupt sleep patterns.
• Underlying Medical Conditions: Certain medical conditions, such as chronic pain, gastroesophageal reflux disease (GERD), and sleep apnea, can cause insomnia.

• Lifestyle Factors: Working non-traditional hours, traveling across time zones, and exposure to screens before bed can contribute to insomnia.

Diagnosis of Insomnia

Diagnosing insomnia typically involves a physical exam, medical history, and sleep history. A healthcare provider may also use the following tools to diagnose insomnia:

• Sleep Diary: A daily log of sleep patterns and habits.
• Actigraphy: A device that tracks movement and sleep patterns.
• Polysomnography (PSG): An overnight sleep study that measures various physiological activities during sleep.

Treatment of Insomnia

Treatment for insomnia depends on the underlying cause and may involve a combination of lifestyle changes, behavioral therapies, and medications.

• Cognitive-Behavioral Therapy for Insomnia (CBT-I): A non-pharmacological approach that helps individuals identify and change negative sleep habits and thoughts.
• Relaxation Techniques: Methods such as progressive muscle relaxation, mindfulness meditation, and deep breathing can help reduce stress and promote relaxation.
• Sleep Hygiene Practices: Establishing a consistent sleep schedule, creating a relaxing sleep environment, and avoiding stimulating activities before bed.
• Medications: In some cases, medications such as benzodiazepines or non-benzodiazepines may be prescribed to help with sleep.

Complications of Insomnia

If left untreated, insomnia can lead to a range of complications, including:

• Mood Disturbances: Depression, anxiety, and irritability.
• Cognitive Impairment: Difficulty concentrating, memory problems, and decreased reaction time.
• Cardiovascular Disease: Increased risk of high blood pressure, heart attacks, and strokes.
• Weakened Immune System: Reduced immune function and increased susceptibility to illnesses.
