Feeling groggy and lethargic even after a good night's sleep? Your alarm clock may be to blame.
Anew studyout of Australia shows that alarms with loud beeps and buzzes can leave you feeling out of it -- and that this "sleep inertia" can last up to four hours. Researchers at the Royal Melbourne Institute of Technology say waking up to music, on the other hand, can help you feel alert first thing.
Study co-author Adrian Dyereven has a couple of suggestions for songs that can help your brain wake up: The Beach Boys' "Good Vibrations" and The Cure's "Close to Me."
