This has been highlighted as a likely factor in the 2010 Air India Express air crash disaster that resulted in 158 fatalities. Initiated upon waking, SI’s symptoms can last for seconds, minutes or hours, where extended SI may impact human performance in a variety of situations and occupations. Sleep inertia ( SI) is a transitional sleep-wake phenomenon characterized by low arousal and reduced cognition. NASA astronaut journal report during orbit aboard the International Space Station. My body apparently went on strike for better working conditions.” ![]() I slept through two alarms, one set for 0600 and another a half-hour later to remind me to take some CEO pictures. Considering that the implementation of auditory assisted awakening is a common occurrence, the musical elements of a chosen waking sound may be an area to further interrogate with respect to counteracting sleep inertia. ![]() Together these findings raise questions regarding the impact melody and rhythm may hold with respect to sleep inertia intensity. Additionally, our secondary analysis revealed that a sound rated as melodic is considered to be more rhythmic than a melodically neutral interpretation. However, the analysis did reveal that a sound which is ranked as melodic by participants shows a significant relationship to reports of reductions in perceived sleep inertia, and in contrast, sound rated as neutral (neither unmelodic nor melodic) returns a significant relationship to the reports of increases in perceived sleep inertia. Our results did not return any significant association between sleep inertia and the reported waking sound type, nor the subject’s feeling towards their sound. This data enabled the analysis and comparison between these responses to identify statistically significant relationships. Through an anonymous, self-report online questionnaire, fifty participants ( N = 50) reported attributes of their preferred waking sound, their feeling towards the waking sound, and perceived sleep inertia after waking. The goal of this research is to understand how a particular sound or music chosen to assist waking may counteract sleep inertia, and more specifically, what elements of these sounds may contribute to its reduction. The type of sound people set as their alarm for waking has been shown to reduce the effects of sleep inertia, however, the elemental musical factors that underpin these waking sounds and their relationships remain unclear. Switch your alarm clock to a classic song by The Cure and reap the benefits.Sleep inertia is a potentially dangerous reduction in human alertness and occurs 0–4 hours after waking. Basically meaning, it can make you feel slow and sluggish for most of your morning, impacting on productivity. The grogginess we may feel during this phase typically lasts for up to 30 minutes, however, periods from 2 to 4 hours have also been reported,” McFarlane told PsyPost. Wondering why fending off grogginess matters so much in the first place? “People need to be aware of sleep inertia’s negative effects on human performance after waking up. Cue a spike in Beach Boys downloads and The Cure scoring a very belated number one with that song, then (fun fact: it only reached a chart peak of 24 in the UK). “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,” said the study's co-author Adrian Dyer. The results showed that more melodic alarm clock sounds were associated with lower levels of grogginess (also known as "sleep inertia", if you want to sound brainy), compared to sounds rated as 'unmelodic', 'somewhat unmelodic', 'neither unmelodic nor melodic', and 'very melodic'. ![]() In order to get the results, McFarlane's team asked 50 participants (which, it's worth noting, is not a huge amount of people), to record the type of sound they used to wake up, along with their "grogginess and alertness levels". After specific tracks to download? They've recommended those too.Īccording to Stuart McFarlane, the study's lead and a doctoral researcher at the Royal Melbourne Institute of Technology, although it's common knowledge that most of us use an audible alarm to wake up, little research has been done into how they can affect the way you feel after you're awake. ![]() Researchers have found that switching your alarm tone to a more melodic sound could help to fend off grogginess. If, like many, you rely on the sound of your phone jingle-jangling to wake up, there could be a super simple way to hack your morning routine and feel more refreshed.
