Sleeping Disorders

Insomnia

Insomnia is characterized by an inability to sleep and/or to remain asleep for a reasonable period of time.  Insomniacs typically complain of being unable to close their eyes or "rest their mind" for more than a few minutes at a time.
However, Insomnia is in fact a symptom of a range of sleep disorders, though a common misconception is that it is itself a sleep disorder.
Insomnia is most often caused by sleep disorders, but other causes include fear, stress, anxiety, and exposure to various medications, herbs, and caffeine.
An overactive mind or physical pain may also be a cause of Insomnia.
Finding the underlying cause of Insomnia is usually necessary to cure it.
Because Insomnia is a symptom of a range of sleep disorders, and not a sleep disorder itself, it will not be discussed further in this eBook.
