Scientists have discovered an unusual and surprising process that occurs in the brain of people suffering from sleep deprivation, and when the system works during wakefulness, the brain is unable to maintain attention at these moments.
According to new scientific research, difficulty concentrating, slow reactions, and decreased ability to think after poor sleep are not simply the result of fatigue, but are linked to a specific biological process occurring in the brain. Research by the Massachusetts Institute of Technology in the United States has examined what changes occur in the brain after sleep deprivation. The research found that in such situations, the movement of a certain fluid increases inside the brain, which temporarily affects the ability to concentrate.
According to research, cerebrospinal fluid or CSF is normally active during sleep and clears the waste products that accumulate in the brain throughout the day. This process is considered very important for mental health, but in the case of sleep deprivation, the same system becomes active even during wakefulness. Researchers say that when the human body works during wakefulness, the brain is unable to maintain attention during these moments. This process is actually an attempt by the brain to compensate for sleep deprivation, but it has to be paid for immediately in the form of a decrease in mental attention.
For this study, 26 volunteers were included, whose tests were conducted in 2 phases. One phase was held after sleep deprivation, while the other was held after full sleep. The next morning, brain functions were evaluated through various mental activities. The results of the research have been published in the scientific journal Nature Neuroscience.
