What Causes Insomnia?

Learn Which Risk Factors You Can Control
  -- By Liza Barnes & Nicole Nichols, Health Educators
Most people have experienced sleep problems at one time or another, but what causes insomnia is very individual. There are actually two different forms of insomnia—secondary (when insomnia occurs as a symptom or side effect of something else) and primary (when insomnia is a disorder in itself, not occurring as the side effect of another condition). Both are characterized by the inability to fall or stay asleep.

There are two main categories of risks that can contribute to insomnia—those that you can't change, and those that you can.

Uncontrollable Risk Factors
These variables are out of your control. Although you can't do anything to change them, it's important to know what has been associated with the development of insomnia. While you can’t change things like health history or your work hours, you can control certain factors related to your lifestyle—the choices you make each day about what to eat and how to care for yourself. These are areas of your life where you can take proactive steps to help prevent and treat insomnia and enhance your overall health.

Controllable Risk Factors
Controllable risk factors are behaviors and factors that you can modify to lower your risk of suffering from insomnia. Some risk factors for insomnia can’t be modified, but many can. Lifestyle changes alone may help you sleep better, but talk with your health care provider if you continue to experience problems—especially those related to factors that you can't control. Every small lifestyle change you can make, in conjunction with the treatment plan laid out by your doctor, can help you sleep soundly and improve your health and energy levels.
