Insomnia is a sleep disorder. It is trouble falling asleep, waking in the middle of the night or waking very early in the morning. Insomnia may also be a sleep that is not restful.
Insomnia is often a short term problem. If it last more than 4 weeks it is considered chronic insomnia.
Insomnia can occur for many reasons. Short term insomnia is often caused by temporary situations or problems with the environment. They may include:
- A life crisis or stress, including the loss of a life partner, divorce, or loss of a job
- Environmental noise
- Extreme temperatures such as a room that is too hot or too cold
- Change in the surrounding environment
- Sleep/wake schedule problems, such as those due to jet lag
There may be no clear reason for chronic insomnia. It may also be due to other medical or psychiatric conditions. Examples of these conditions that can lead to sleep problems include:
- Heart disease
- Asthma or chronic obstructive pulmonary disease
- Sleep apnea
- Gastroesophageal reflux disease (GERD) or ulcer
Both chronic and short term insomnia may be due to
- Behavioral factors, including:
- Misuse of caffeine, alcohol, smoking cigarettes, or other substances
- Disrupted sleep/wake cycles from shift work or other nighttime activities
- Chronic stress
- Excessive napping in the afternoon or evening
- Medicines such as:
- Certain allergy medicines
- Certain asthma medicines
- Some Blood pressure medicines
- Psychiatric medicines
