80% of people with sleep apnea are unaware that they have it. If you regularly feel tired during the day, even after sleeping more than 8 hours, you may be one of them. Take the test to see if you are at risk for having or developing sleep apnea.
Widely underdiagnosed, sleep apnea can also have serious health consequences. In addition to causing excessive fatigue, it can also lead to cardiovascular diseases and increase the risk of diabetes and depression.
