When the alarm goes off after a late bedtime and a restless night, most of us are tempted to hit the snooze button. Resist the urge—it'll only make things worse.
Mary A. Carskadon, PhD, a professor of psychiatry and human behavior at Brown University, explains to Huffington Post that hitting the snooze button causes what's known as drockling: the phenomenon of drifting in and out of sleep in the early morning. Drockling feels great, and there's a reason. Your body temperature naturally warms up a couple of hours before your body is ready to wake up. If your alarm clock wakes you up before you're ready, your body temperature is at its lowest, and braving your cold bedroom can feel like the most terrible punishment. In that scenario, your cozy covers feel like the greatest thing ever. As your head sinks back into your pillow, however, know that you're making your morning that much harder.
