Beep beep beep or Beach Boys? The sound of your morning alarms could be affecting how groggy and clumsy you are in the morning.
Why This Matters: Don’t talk to us before our second coffee.
If you wake up with a harsh ‘beep beep beep’ alarm you might be starting your day off on the wrong foot.
According to new research, by RMIT University, melodic alarms could improve alertness levels, with harsh alarms linked to increased levels of morning grogginess.
Morning grogginess is a serious problem with serious ramifications
Stuart McFarlane, who led the research, says morning grogginess – or sleep inertia – was a serious problem in our 24-hour world.
“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,” he says.
“You would assume that a startling ‘beep beep beep’ alarm would improve alertness, but our data revealed that melodic alarms may be the key element. This was unexpected.
“Although more research is needed to better understand the precise combination of melody and rhythm that might work best, considering that most people use alarms to wake up, the sound you choose may have important ramifications.
“This is particularly important for people who might work in dangerous situations shortly after waking, like firefighters or pilots, but also for anyone who has to be rapidly alert, such as someone driving to hospital in an emergency.”
Harsh alarms may disrupt or confuse brain activity
The research involved 50 participants, using a specially designed online survey that enables them to remotely contribute to the study from the comfort of their own home.
Each person logged what type of sound they used to wake up, and then rated their grogginess and alertness levels against standardised sleep inertia criteria.
Co-author Adrian Dyer says the research could help contribute to the design of more efficient interventions for people to use on their own devices to wake up properly.
“This study is important, as even NASA astronauts report that sleep inertia affects their performance on the International Space Station.”
“We think that a harsh ‘beep beep beep’ might work to disrupt or confuse our brain activity when waking, while 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,” he says.
“If we can continue to improve our understanding of the connection between sounds and waking state, there could be potential for applications in many fields, particularly with recent advancements in sleep technology and artificial intelligence.”
