| Listening to music before going to bed, the more you listen, the more tired you are, it turns out that the "earworm" is at work |
Many people have the habit of listening to music to fall asleep, believing that it helps sleep
.
But this method is completely useless for some people, and the more you listen, the more energetic you become
Michael Scullin, associate professor of psychology and neuroscience at Baylor University, found that when he woke up in the middle of the night, a song lingered in his mind, which affected his sleep quality
.
So he began to study the relationship between listening to music and sleep
He focuses on a mechanism that is rarely explored: when a song or melody is played repeatedly, people will often repeat the song (or melody) in their minds as if they have been brainwashed, even unconsciously.
Humming, this is called the "earworm effect"
.
"Earworms" are unconscious musical imaginations that usually occur when awake, but Scullin discovered that they can also occur when trying to sleep
Scullin said: "Teenagers and young adults usually listen to music before going to bed, but the more you listen to music, the more likely you are to catch the lingering earworm
.
When this happens, your sleep May be affected
The study investigated the sleep quality, music listening habits, and frequency of hearing "earworms" of 209 participants, including how often they heard "earworms" when trying to fall asleep, waking up in the middle of the night, and just waking up in the morning
.
In addition, the researchers also brought 50 participants to Scullin's sleep neuroscience and cognitive laboratory to try to study how "earworms" affect sleep quality
It was found that participants who experienced the "earworm effect" had more difficulty falling asleep, waking up more at night, and spending longer time in the light sleep phase
.
Compared with people who rarely experience "earworm", people who experience "earworm effect" one or more times a week are 6 times more likely to have poor sleep quality
Surprisingly, the study found that some instrumental music (unvoiced) is more likely to cause the "earworm effect" and destroy sleep quality than lyrical songs.
The "earworm effect" caused by instrumental music is twice that of other music
.
In addition, the researchers also quantitatively analyzed the EEG readings (records of brain electrical activity) of the 50 subjects to test the physiological markers of sleep-dependent memory consolidation
.
"Participants who experience the "earworm effect" during sleep exhibited slower vibrations during sleep, which is a sign of memory reactivation,
Scullin said that almost everyone thinks that listening to music can improve sleep, but we found that those who listen to music more have worse sleep quality
.
How to get rid of the "earworm effect"? Scullin suggested that first try to listen to music moderately, and if you are disturbed by "earworms", you can occasionally rest
.
"The timing of listening to music is also very important.
Try to avoid listening to music before going to bed
.
" He said: "If you often listen to music in bed, then you will have this association, even if you don't listen to music, when you want to sleep , It may also trigger the'earworm effect'
.
"
Another way to get rid of "earworms" is to participate in cognitive activities.
Fully focusing on a task, problem or activity can help distract the brain from the "earworms"
.
Scullin advises not to participate in demanding activities or do things that interfere with sleep before going to bed, such as watching TV or playing video games
.
Spending 5 minutes before going to bed to write down the tasks you are about to complete will help you "get rid of" worries about the future and thus make you fall asleep faster
