Insomnia: Understanding Sleep Difficulties
Individuals experiencing challenges with falling asleep, fragmented sleep patterns, or a combination of both are classified as suffering from insomnia. Notably, those with insomnia often wake up feeling unrefreshed and fatigued, manifesting various symptoms throughout the day. Insomnia is one of the most prevalent sleep disorders, with the American Psychiatric Association indicating that approximately one-third of adults report experiencing insomnia symptoms. However, only about 6-10% of adults display symptoms severe enough to meet the diagnostic criteria for insomnia. A diagnosis of insomnia is made when certain criteria are met, including difficulty sleeping at least three nights per week for a minimum of three months, alongside a negative impact on daily functioning.
Causes of Insomnia
The underlying causes of insomnia can vary significantly depending on the type of insomnia one is experiencing. Individuals may suffer from acute insomnia, where symptoms last from one night to a few weeks, or chronic insomnia, which occurs at least three nights per week for one month or longer. Below are some common factors associated with each type:
- Causes of Acute Insomnia:
- Stress or anxiety.
- Illness.
- Environmental factors such as noise, light, and extreme temperatures.
- Physical or emotional discomfort.
- Disruption of the natural sleep schedule due to travel or shift work.
- Causes of Chronic Insomnia:
- Depression and anxiety disorders.
- Chronic stress conditions.
- Persistent pain or discomfort during the night.
Types of Insomnia
Insomnia can be categorized based on multiple criteria. The two primary classifications include acute and chronic insomnia, as previously mentioned. Additionally, insomnia can be categorized based on its association with other health conditions as follows:
- Primary Insomnia: This type occurs independently and is not directly linked to other health issues.
- Secondary Insomnia: This type is a consequence of another health problem, such as asthma, depression, cancer, arthritis, and gastroesophageal reflux disease, and can also stem from medication use or substances like alcohol.

Individuals suffering from insomnia may experience a variety of symptoms, including the following:
- Daytime sleepiness.

- Excessive irritability.
- Difficulty falling asleep.
- Waking up during the night and struggling to return to sleep.
