And it could have an impact on your day-to-day function.
“If you don’t wake properly, your work performance can be degraded for periods up to four hours and that has been linked to major accidents,” said lead author Stuart McFarlane.
“This is particularly important for people who might work in dangerous situations shortly after waking, like firefighters or pilots."
The solution? Switch up that morning bell with something more melodic, say scientists. However, they're still yet to find the optimal tune that can help the waking up process.
Meanwhile, study co-author Adrian dyer said that the typical beeping noise of an alarm is possibly confusing brain activity during the early hours, a potential cause of grogginess at the start of the day.
“Whereas a more melodic sound, like The Beach Boys’ Good Vibrations or The Cure’s Close to Me may help us transition to a waking state in a more effective way,” Prof Dyer said.
“Even NASA astronauts report that sleep inertia affects their performance on the International Space Station,” Prof Dyer said.
The findings were published in the scientific journal PLOS One.
