Maybe you're just not getting enough sleep at night - but maybe you're experiencing a sleep disorder instead.

Sleep is as important to the body as eating - but nearly one in every three Americans fails to get a good night's sleep for various reasons. About 100 million are chronically sleep deprived, and that number is rising due to changing lifestyles and increased family and financial pressures.

An estimated 40 million Americans feel exhausted because they are experiencing a sleep disorder. Chronic sleep disorders can disrupt family life, affect productivity at work, contribute to motor vehicle accidents, and even result in death.

Yet about 95 percent of people with sleep disorders go undiagnosed and untreated, simply because they do not realize they have a problem or think that nothing can be done for them.
