When sleep becomes elusive night after night, you may be experiencing insomnia—a common sleep disorder that affects millions of people worldwide. This article provides a comprehensive overview of insomnia, from understanding its causes to exploring both medical treatments and natural remedies.
What Is Insomnia?
Insomnia is a sleep disorder characterized by difficulty falling asleep, staying asleep, or both, despite having adequate opportunity for sleep. It may be short-term (acute) or can last for months or even years (chronic).
People with insomnia often feel dissatisfied with their sleep and may experience one or more of the following symptoms:
- Difficulty falling asleep at night
- Waking up during the night
- Waking up too early

Types of Insomnia
Insomnia is typically classified into two main types:
Acute Insomnia: Brief sleep difficulties lasting for days or weeks, often triggered by life stressors or changes in environment.
Chronic Insomnia: Sleep difficulties occurring at least three nights per week for three months or longer.
Insomnia can also be categorized based on its cause:

Secondary Insomnia: Sleep problems that are symptoms or side effects of another medical condition, medication, or substance.
