Daytime sleepiness is a key sign of sleep apnea, ranking right next to snoring and insomnia as one of the more common symptoms that lead people to seek diagnosis for obstructive sleep apnea (OSA).
Everyone experiences occasional daytime sleepiness – those of us trying to juggle the demands of family, work and daily responsibilities know that it’s not always possible to get those recommended eight hours of sleep every night. But if you feel drowsy during the day on a regular basis, despite no real change in your daytime habits or schedule, it’s time to talk to your doctor about taking a sleep test.
Why? As you may know, sleep apnea is a chronic condition that disrupts not only your sleep but also your day-to-day lifestyle, and can lead to serious health problems if not properly treated.
Sleep apnea is caused when your airway is obstructed, which pauses your breathing throughout the night. You may not awaken when this happens – or, more likely, you may awaken and not remember it – but either way, your sleep is disrupted, and the result is you wake up feeling drowsy and low on energy. Worse than daytime sleepiness, untreated OSA can also increase the risk of more serious health problems like high blood pressure, obesity and even heart failure, according to the National Heart, Lung, and Blood Institute (NHLBI).1
