According to the American Sleep Apnea Foundation, 30 million adults in the U.S. are living with sleep apnea, but more than 80% are unaware they have this condition. Most people don’t realize they’re experiencing breathing problems and certainly can’t judge its severity. The three types of sleep apnea are obstructive, central and mixed. OSA is the most common, affecting an estimated 25–34% of men and 10–17% of women. Worldwide, OSA impacts 1 billion people, with an estimated prevalence exceeding 50% in some countries. Studies indicate 7–69% of individuals seeking treatment for insomnia also have sleep apnea. Conversely, the co-occurrence of insomnia ranges from 6–84% in individuals seeking treatment for sleep apnea-related symptoms (e.g., snoring, excessive daytime sleepiness and nocturnal breathing issues).
