    People may set an alarm on the phone or clock that sounds like this: beep beep beep. That hard, unpleasant sound may be making it harder to shake off the sleepy feeling in the morning known as grogginess. So, is there a better way to wake up? A recent study says yes. The answer is music.

The study, carried out by researchers in Australia, involved 50 people. The researchers found that people who wake up to musical alarms reported feeling more awake and alert. Stuart McFarlane, a lead writer of the study stated, "We are very surprised by these findings as one might expect a harsh beeping sound to be more successful," at waking up a person.

Sleep inertia is another term for grogginess. It means a person has a heavy feeling when waking up, and has trouble getting moving again after sleeping. McFarlane said people need to better understand sleep inertia's harmful effects on human performance later in the day.

Not everyone will experience the full effect. But for those who do, "care should be taken" when performing duties that require a top performance within this period, he said. This includes "dangerous tasks like driving or riding our bikes" shortly after waking up. The same is true for people who work in dangerous situations shortly after they wake, including firefighters and pilots.

So, what makes musical alarms better for waking up? The researchers think the music may be more successful in reducing sleep inertia because it has several tones, compared to the single tone of a "beeping" alarm. McFarlane said that the changes over time between the music tones may help increase a person's attention when waking from sleep.

And is there a kind of music that is best to wake up to? There may be, McFarlane said. "We could suggest alarm sounds that are tune full and easy to hum or sing along with. The current sounds I have been using include 'Close to me' by the Cure and 'Borderline' by Madonna."

No matter how you wake up, experts say, the amount of sleep you get also matters — a lot.
