It turns out that just changing the alarm sound dramatically improves awakening, what kind of sound is best?

Hydration and light exercise are recommended to help you wake up in the morning, and loud alarm clocks have appeared. Meanwhile, a research team at the Royal Melbourne Institute of Technology discovered that changing the 'alarm sound type' dramatically improved awakening.

Snooze blues? How using your favorite song as an alarm can help you wake up more alert

According to the research team, the state where the head does not work immediately after waking up is a physiological phenomenon called 'sleep inertia ', and in Australia, sleep inertia causes an annual economic loss of A $ 17.9 billion (about 1.5 trillion yen). (PDF link) It is said that it has occurred.Techniques such as caffeine intake and sunbathing are widely used to improve this sleep inertia, but the research team newly investigated the relationship between 'type of alarm alarm voice' and good awakening.

The research team asked the subjects 'ALARM TONE', 'Melody-rich song (MUSICAL SONG)', 'Melody-rich musical instrument sound (INSTRUMENTAL MUSIC)', and 'Environmental sound such as bird calls and water currents (NATURAL)'. Four types of alarm sounds of 'SOUNDS)' are heard when waking up, and the frequency of feeling sleep inertia is in four stages of 'just a little (orange)', 'sometimes (gray)', 'often (blue)', and 'every time (black)'. I was allowed to evaluate it. As a result, it was found that awakening is better when music or environmental voice is used as an alarm than when a monotonous buzzer sound is used as an alarm.

Next, the research team compared the results of two groups that used 'monotonous buzzer' and 'music' as alarm sounds by playing a simple game app to wake up. As a result, the group that used music as an alarm recorded higher results. From these experimental results, the research team concludes that 'using music as an alarm sound can improve sleep inertia.'

The research team 'found that the type of alarm sound can improve sleep inertia.' 'In recent years, wearable devices and health monitoring technologies have made rapid progress. Combining this field with the findings of this study. It may be possible to select the best alarm sound for different situations. '
