It may seem that a loud and alarming signal increases alertness and concentration. But this is not the case, writes MedicalNewsToday.
The scientists worked with fifty participants. They took as a basis such an indicator as sleep inertia. This is an intermediate state between watching dreams and waking: a person would like to return to sleep, is exhausted, but realizes that he must wake up.
The longer and more intense the state of sleep inertia upon first awakening, the more intense the morning feeling of discomfort and confusion becomes.
Scientists have learned what type of alarm sounds the participants choose and how wakeful or sleepy they feel in the morning. It turned out that people who preferred melodic, pleasant alarm clocks felt more collected and efficient in the early hours. If the sounds of the alarm clock turned out to be sharp, intermittent, the participants in the experiment were overwhelmed, disoriented, and disoriented.
The study is especially relevant for those who work in extreme situations: doctors, pilots, rescuers, police officers. Even NASA astronauts say sleep inertia strongly affects their performance on the ISS.
"We think a harsh sound disrupts brain activity upon waking, while a more melodic sound helps to smoothly transition into an active state," the study authors note. "We will continue to explore the relationship between alarm sounds and human well-being."
