A group of specialists representing the University of California at Los Angeles, concluded that lack of sleep changes the perception of the person around the world. The result can be a slow reaction, and in some cases even more noticeable problems.
The study involved 12 people with epilepsy. Specialists chose these people, because by the beginning of the study, doctors were already monitoring their brain activity with electrodes (this observation increased the chances of finding effective treatment for patients).
Asking the participants to distribute different images by category as quickly as possible, the researchers noticed that on average, well-qualified volunteers cope better with this task. Specialists also came to the conclusion that during the test, the brain waves of the “sleepiest” participants were slowed down, that is, they were literally “asleep on the run” – at least, it concerned some parts of their brain. It is alleged that this can also lead to problems with vision and even failure in memory.
Based on the results obtained, scientists suggest that a sleepy man behind the wheel can be a danger to himself and others – he may not notice the pedestrian walking in front of the car.
The study was published on the pages of the scientific publication Nature Communications.
This is not the only study whose authors express the fear that a lack of sleep can cause a person to “sleep on the move”, including driving. Last year, other specialists found out that people who during the month regularly gave less than six hours of sleep a day could sink into themselves unnoticed, even if they themselves thought that they were cheerful and did not want to sleep. At the same time, it seemed to the participants that during the experiment they did not sleep a second.
Some other scientists in the past have revealed several more possible unpleasant consequences of lack of sleep. In particular, they have received evidence that the lack of sleep makes a person more prone to risk and even to the development of alcoholism, and can also negatively affect the figure as indirectly (a sleepy person often eats more than a sleepy), and directly sometimes lack of sleep adversely affects the intestinal microflora).
