What Causes Insomnia and How Can it be Treated
Insomnia can be caused by psychiatric and medical conditions, unhealthy sleep habits, specific substances, and/or certain biological factors. Recently, researchers have begun to think about insomnia as a problem of your brain being unable to stop being awake (your brain has a sleep cycle and a wake cycle—when one is turned on the other is turned off—insomnia can be a problem with either part of this cycle: too much wake drive or too little sleep drive). It's important to first understand what could be causing your sleep difficulties.

In order to properly treat and cure your insomnia, you need to become a sleep detective. Emotional issues such as stress, anxiety, and depression cause half of all insomnia cases. But your daytime habits, sleep routine, and physical health may also play a role. Try to identify all possible causes of your insomnia. Once you figure out the root cause, you can tailor treatment accordingly.

Sometimes, insomnia only lasts a few days and goes away on its own, especially when the insomnia is tied to an obvious temporary cause, such as stress over an upcoming presentation, a painful breakup, or jet lag. Other times, insomnia is stubbornly persistent. Chronic insomnia is usually tied to an underlying mental or physical issue.

Examples of medical conditions that can cause insomnia are:

• Nasal/sinus allergies
• Gastrointestinal problems such as reflux
• Endocrine problems such as hyperthyroidism
• Arthritis
• Asthma
• Neurological conditions such as Parkinson's disease
• Chronic pain
• Low back pain

Psychological problems that can cause insomnia: depression, anxiety, chronic stress, bipolar disorder, post-traumatic stress disorder.

Medications that can cause insomnia: antidepressants; cold and flu medications that contain alcohol; pain relievers that contain caffeine (Midol, Excedrin); diuretics, corticosteroids, thyroid hormone, high blood pressure medications.

Sleep disorders that can cause insomnia: sleep apnea, narcolepsy, restless legs syndrome.

If you have trouble sleeping on a regular basis, it's a good idea to review your health and think about whether any underlying medical issues or sleep disorders could be contributing to your sleep problems. In some cases, there are simple steps that can be taken to improve sleep (such as avoiding bright lighting while winding down and trying to limit possible distractions, such as a TV, computer, or pets). While in other cases, it's important to talk to your doctor to figure out a course of action. You should not simply accept poor sleep as a way of life—talk to your doctor or a sleep specialist for help.
