Why is it that when you need to have a good night of sleep you always seem to toss and turn? Those occasional sleepless nights—like the one before a big presentation at work—are actually quite harmless. Studies even show that you’ll still be able to perform just fine the next day.
Trouble arises when you feel fatigued day after day. In that case, you may not be getting quality sleep during the night. The reason may be sleep apnea, a chronic medical condition that pauses breathing while you sleep. Fortunately, sleep apnea is treatable if a sleep study shows that you have the condition.
