Insomnia is a common sleep disorder that affects people of all ages and backgrounds. It is characterized by difficulty falling asleep, staying asleep, or waking up too early and not being able to get back to sleep. Insomnia can have significant impacts on daily functioning, including mood, energy levels, and cognitive performance. This comprehensive guide provides an in-depth look at insomnia, covering its causes, symptoms, diagnosis, and treatment options.
Causes of Insomnia
Insomnia can be triggered by various factors, including:
- Stress and Anxiety: Stressful life events, such as work pressures or family issues, can lead to anxiety and make it difficult to fall asleep or stay asleep.
- Depression: Insomnia is often linked to depression, and both conditions can exacerbate each other.
- Habits and Lifestyle: Poor sleep hygiene, such as irregular sleep schedules, excessive caffeine or alcohol consumption, and exposure to screens before bedtime, can contribute to insomnia.
- Environmental Factors: A noisy or uncomfortable sleeping environment can disrupt sleep.
- Medical Conditions: Chronic pain, asthma, and other health issues can interfere with sleep.
- Medications: Certain medications, including some antidepressants and stimulants, can cause sleep disturbances.
- Substance Abuse: The use of drugs or alcohol can lead to insomnia.
Symptoms of Insomnia
People with insomnia may experience:

Diagnosis of Insomnia
A healthcare professional can diagnose insomnia through:
