Based on statistics, greater than one third of the population in the United States has insomnia. Insomnia is the most common and most prevalent sleeping disorder. In determining the type of insomnia present, the onset insomnia is identified as well as the source for the development of the condition. Speaking in terms of the onset of insomnia, there are three types. Transient insomnia would occur for some days, while short term insomnia would usually exist for a couple of weeks, and chronic insomnia is identified when insomnia is present for more than three weeks. If the source of insomnia would be identified, two types would be considered and these are primary and secondary insomnia.
Of all the classifications based on the onset or duration, the most common would be transient insomnia. Most people are experiencing insomnia for a couple of days and would usually return to normal after some time. Causes of transient insomnia may vary from stress or work related issues such as shifting of schedules. Usually, transient insomnia can also be caused by jet lag due to traveling. This type of insomnia would disappear after sometime without receiving any treatments whatsoever. Stress can also cause short term insomnia. Such causes would also be the same for transient insomnia but it just happened for a few more days than that of transient insomnia. However, if short term insomnia is left untreated, it could lead to chronic insomnia.
