It is important for the student to know that an apneic event may take place up to twenty or thirty times per hour - sometimes even more - followed by a noted episode of snoring. Important to note is the fact that snoring, in and of itself, is not indicative of sleep apnea; rather, it is but one telltale symptom (Sleep Apnea). Sleep apnea may occur during the inherent relaxation associated with sleep, when the tongue and throat muscles soften and inevitably block the airway. This relaxation goes even further when the soft palate muscles and uvula (fleshy tissue) sag over the airway as well, creating the "labored and noisy" (Sleep Apnea) so readily associated with the condition. It is important for the student to know that there are times when this blockage causes breathing to stop entirely. Interestingly, those who suffer with sleep apnea do not realize it, inasmuch as another person typically hears the startling noises and suggests that there is a problem. The sufferer may display frequent episodes of falling asleep on the job, giving work associates the clue, as well. "People with sleep apnea usually aren't even aware they have a problem and may not believe it when told" (Sleep Apnea). Inasmuch as sleep apnea is potentially life threatening, it is imperative that the sufferer seeks immediate diagnosis and treatment. Early recognition and treatment of obstructive sleep apnea is a critical step not only in getting a more restful night's sleep, but also in avoiding the potential complications of irregular heartbeat, high blood pressure, heart attack and stroke. Sleep apnea is more prevalent in men and young African-Americans; however, it has been diagnosed during all life stages. It is important for the student to know that attaining proper diagnosis of obstructive sleep apnea includes consultation with a primary care physician, pulmonologist, neurologist and/or other specially trained physician in order to obtain a definitive diagnosis and begin appropriate treatment.
