What causes insomnia?
Sleep can be disrupted by an infinite number of stressful events. Almost everyone has occasional insomnia due a stressful event such as the death of a loved one. Some people can have more frequent insomnia and develop a sleep disorder called Primary Insomnia. Anybody can get insomnia, but certain groups of people tend to be more at risk such as women and older people. A troubling period of insomnia that continues for more than a few days usually has a combination of underlying causes.
The most common causes to consider are:
- Ongoing worry and anxiety about situations
- Life stressors (stressful relationships, work, law suits, discrimination)
- A predisposition to be more aroused (physically and/or mentally)
- Medical problems
- Psychiatric problems
- Factors in the sleep environment (bed, bed partner, noise, light)
- Unhealthy sleep patterns
- Negative attitudes about sleep
