The number of people who suffer from sleep disorders is truly astounding. If you add up patients who suffer from both chronic (persistent) and occasional sleeping issues, approximately 60 million people every year in the U.S. alone have a sleep disorder.
One issue with sleep disorders is that they're not always recognized as mental health issues. People often attribute sleeping problems to having "too much work and not enough time" or mistake a sleep disorder for regular sleepiness or being tired. However, being tired every day for an extended period of time is not normal and is a definite cause of concern.
While the most well-known sleep disorder is insomnia, the American Psychiatric Association recognizes almost 20 sleep-related conditions, some of which can be classified into sleep-wake disorders, parasomnias, breathing-related sleep disorders.
