What is insomnia?

Experts have identified three types of insomnia: pass, intermittent and chronic.

Transient insomnia occur over a period ranging from one night to a few weeks.

Acute insomnia is the inability to consistently sleep well for a period of between three weeks to six months.

Chronic insomnia occurs through lack of sleep almost every night and can last for years. It can be caused by another disorder, or it can be a primary disorder. Its effects can vary according to its causes. They might include sleepiness, muscular fatigue, hallucinations, and/or mental fatigue

Most people have been touched by a transient insomnia and / or acute insomnia at a time. This type of problem is not necessarily considered a disorder, but most often the result of a state of anxiety, a certain medication, disease or stress associated with an event such as job loss or a life partner.  Studies show that the incidence rate of insomnia for females is 40% higher, especially among those who exceed the age of 40 years. Also, older people often feel episodes of insomnia, usually due to medical problems, and needs a rest.

Contrary to other wrong conceptions, insomnia is not necessarily defined as a reduction in the amount of sleep, but rather is related to the quality of sleep. In fact, regardless of how long is the sleeping period, you may experience insomnia.  To appreciate this, it is important to understand “architecture” of your own sleep, meaning that the pattern changes during REM (rapid-eye-movement) sleep and the dreaming, and non-REM period.
