You’re sleepy all the time
“Many people feel tired, but don’t know why and attribute it to lack of sleep, among other things,” says Boris Chernobilsky, MD, director of sleep and airway surgery at Mount Sinai Beth Israel in New York City. Daytime sleepiness is one of the most common sleep apnea symptoms, but men with sleep apnea tend to report daytime sleepiness more often than women, says Dr. Chernobilsky. Also, when you have sleep apnea, you wake up frequently throughout the night.
