What causes Insomnia?
There are a number of potential causes of insomnia. Excessive stress is the most common cause of short term or temporary insomnia. Most chronic insomnia can be caused by anxiety, depression, medical conditions, lifestyle changes, poor sleep habits, medications, behavioral issues, poor diet, lack of physical exercise, or over stimulation. The prevalence of insomnia becomes greater as people age, most often because of changes in sleep patterns, activity, health, or lifestyle. The populations most at risk for insomnia are women, elderly, people with a mental health diagnosis, night shift or rotating shift workers, or people who travel long distances frequently.
How is Insomnia diagnosed?
Insomnia is most commonly diagnosed by a physician; however, can be diagnosed by other mental health and medical professionals. In most cases a questionnaire is used to asses sleep patterns and habits, as well as symptoms or complications from sleep or lack of. A sleep diary is also a useful diagnostic tool. Physical exams, blood tests, and sleep studies can also be used to rule out other medical conditions that could cause or mimic insomnia.
How is Insomnia Treated?
Behavioral therapy is a very common tool used to treat insomnia, especially when medications are not a good option. The focus of therapy is to change behaviors that negatively impact sleep and create healthy sleep patterns; as well as addressing the underlying causes such as stress or mental health issues. These therapies generally include education about healthy sleep habits, Cognitive Behavioral Therapy, Relaxation and Mindfulness techniques, Environmental changes to reduce factors and stimulation that impacts sleep, sleep restriction, paradoxical intention or remaining passively awake, and light therapy. Initial treatment will almost always focus on changing sleep habits, including:
- Reducing stimulation in the place of sleep, removing electronics
- Creating a comfortable environment
- Reducing time spent in bed, only spending time for sleep or intimacy in bed
- Creating a regular sleep schedule with consistent sleep and wake times seven days a week
- Initially reducing time sleeping in order to create increased tiredness and successful sleep
- Increase activity, improve diet, reduce or stop behavioral issues
- Address underlying mental health or medical conditions with appropriate treatment
If behavioral therapy techniques are not successful, both over-the-counter and prescription medication options are available.
