How the Brain Responds to Sounds while Sleeping

Do you know how your brain reacts to unfamiliar sounds while you sleep? According to experts, while sleeping, our brain is most alert about unknown and unfamiliar sounds.

 

Researchers did a study on this in which 17 volunteers were included. Of these, 14 were women who did not have any kind of sleep disorder. The average age of all of them was 22 years. Scientists have tried to know through this study how the human brain behaves while sleeping.

How the brain responds to sounds

Earlier it was believed that the human body remains physically and mentally inactive while sleeping. However, studies and research that came after that claim that our body and our brain keep working all night and it is also very important for health.

Researchers in Austria looked at the brain activity of adults while sleeping and tried to learn how our brains react to unfamiliar and familiar sounds.

 

The study, led by researchers from the University of Salzburg, has been published in the journal JNeurosci. In this study, scientists found that the human brain pays special attention to unfamiliar and unknown sounds. This happens because, even in sleep, the brain remains alert about potential dangers.

According to scientists, there are two main types of sleep. One of these is rapid eye movement (REM) and the other is on-rapid eye movement (NREM) sleep. NREM is the first stage of sleep and the study revealed that during this stage, when you hear unfamiliar sounds while you sleep, the human brain in a way tune-in itself.

Through this study, scientists have tried to explain how the brain starts monitoring the environment around us in which we live, even if our eyes are closed at that time.

Brain on Higher Alert

In this study, scientists explained how unfamiliar sounds, whether they are coming from TV, music or anywhere, prevent you from getting a restful and restful sleep at night. This happens because the brain is still on higher alert at that time. The mind is fully alert about these sounds.

In the results of the study, scientists have said that during NREM sleep, unfamiliar sounds act as strong promoters of brain response.
