introduction

Sleep disorders affect many people, children as well as adults. Do you have a sleep disorder? You might and you just do not know it. Sleep has four stages and people usually go through them often while they are sleeping. Everyone needs sleep as well as water, food, and air. Without sleep we might become irritable and not able to perform well at work or everyday in life. According to Rob Nagel, “a sleep disorder is any condition that interferes with our regular sleep cycle, ranging from insomnia to narcolepsy.” In order to properly identify and treat sleep disorders it is necessary to first define them and differentiate their symptoms from normal sleep behavior.
