Sleep disorders affect millions of people each and every day and, while insomnia is one such condition that can affect the quality of sleep, there are many other disorders. Still, many people don’t seek treatment for their sleep disorder, either because they don’t recognize the symptoms or they don’t take the condition to be serious. They assume that failing to get enough sleep is just a temporary problem that will eventually correct itself, or they don’t view a sleep disorder as a life-threatening medical condition. In fact, an untreated sleep disorder can lead to a whole host of physical and mental illnesses.
