(CNN) Many people dread the blaring sound of an alarm clock, signaling the start of a busy workday. Waking up minutes or even hours before the alarm is not a new phenomenon, sleep experts tell CNN, but it can cause people incredible discomfort. An acute sleep disorder could be at play for someone not experiencing chronic insomnia but waking up early. Checking your clock when you wake up early can trigger stress and make it hard to go back to sleep, experts say. "When you do that, when you let the pressure go that sleep isn't so effortful, sleep is more likely to come back."
