Lack of sleep reduces the volume of the brain - the results of the study.
Scientists studied dozens of MRI scans of adults. It turned out that sleep problems physically change the structure of the brain for the worse. This leads to impaired memory, decreased concentration and impatience.
Also, similar side effects occur in people with insomnia, apnea and sleepwalking. For this reason, their reaction time and alertness deteriorate during the day.
