If you lack sleep about 1 hour can be the day you are nothing but it will not affect the brain as small as you least expect them to. This is the argument given by psychologist Jakke TAMMINEN.
1959, Peter Tripp, a famous DJ in New York attended a charity program and pledged not to sleep for 200 hours while continuing working in radio programs on his radio.
the study of the effects of lack of sleep at a time that is very rare, no one knows what will happen if the lack of sleep in such a long time. This makes it the first major event, not only for millions of Tripp audience but also with the scientific community.
The impact of not sleeping turn deep into the minds of Tripp's sleep is far from over anyone had expected. Tripp whose capital is optimistic cheerful personality but he has changed considerably as a probation period elapsed. On the third day, he had become very irritable, swearing and humiliation even with their best friends. To the last hours in which he had 200 hours string into a state of paranoia.
But despite the concerns of the medical supervision and with the support of stimulants they gave Tripp, he still persistently maintain your goals and go to bed after 201 hours of continuous mode.
the research in modern labs have replicated some of the behaviors seen in Tripp as a result of insomnia. Insomnia or scissors trying to prolong sober will cause the body to reduce the ability to control bad mood as well as significantly increased feelings of anger, anxiety, depression and sometimes even more. Some people believe that insomnia leads to extremism while expressing emotions.
Fatigue and psychological condition
Like Tripp, can fight with his friend when not enough sleep, the participants in a study small research, when sleep deprived easily become more stressful and more angry when asked to do a simple cognitive test.
method brain scans showed why lack of sleep can lead to emotional reactions are not rational. When people engage in sleep deprivation studies show negative emotions, the amygdala, a region deep in the brain, is the control center of our emotions, activity is much higher 60% than those who get enough sleep normally.
the researchers also looked at how different brain regions are connected in the participants. They found that lack of sleep has broken the link between the amygdala and prefrontal cortex between. This is important because between the prefrontal cortex is the intermediary agencies, self-regulation of the accounting function. Insomnia causes the amygdala to overreact to negative stimuli because it is disconnected from the normal area of moderate brain reacts to it.
Sleepless in Las Vegas
casino owner for many years in said Las Vegas gamblers often wake tired in a long time, so often make risky decisions. Lights, noise, and lack of windows prevents them realize time is passed.
In 2011, researchers at Duke University have made one test for all players in the casino, the researchers sets out the options for gamblers include increasing the level of real money, reduce the level of lost money or increase your chances of winning in the first game.
When the study participants were deprived of sleep only in one night, they start making decisions under 1 second trend is more cautious for fear of losing, 2 is riskier bet in the door in order to maximize profits can be obtained. In other words, lack of sleep makes them risky gamble more and also more feasible, changes in risk behavior was accompanied by changes in the activity of the brain, depends evaluating the results of the brain that is negative or positive.
sleep to learn
another area of the brain affected by lack of sleep is the hippocampus. This is an important area containing the new memories. When people are deprived of sleep even for one night, the ability to remember new information significantly reduced. This was demonstrated in one study of the weakening of the hippocampus due to lack of sleep.
When asked to remember a set of images, the sleep-deprived people showed less activity stimulated the hippocampus than people get enough sleep. Thus says lack of sleep can reduce the ability to write new information in the brain. In addition, the hippocampus might need some time to go to sleep your body to move the new information is stored in other areas of the brain. In this case, lack of sleep can cause the hippocampus to limited storage, preventing new information to be stored.
The lesson from the lack of sleep
Tripp's story had a nice little ending. Shortly after joining the trial did not sleep for 201 hours, his marriage fell apart, he lost his job and ended his career
