Many people in western societies, however, get considerably less sleep. According to studies, about one-third of the persons surveyed in several industrial countries reported too little sleep. <strong>If a young adult sleeps less than 8 hours a night, increased attention deficits occur, which can lead to considerable negative consequences<\/strong>. In sleep clinics there is an increasing number of healthy people who are suffering from the negative consequences of insufficient sleep.<\/p>\n<div id=\"text\">\n<p><strong>Not enough sleep leads to riskier decision-making<\/strong><\/p>\n<p>Researchers at the University of Zurich and the University Hospital Zurich have now identified a further critical consequence of a chronic lack of sleep: <strong>increased risk-seeking<\/strong>. The sleep and neuroeconomics scientists studied the risk behavior of 14 healthy male students aged from 18 to 28 years. <strong>If the students slept only 5 hours a night for a week, they displayed clearly riskier behavior in comparison with a normal sleep duration of about 8 hours<\/strong>. Twice a day, they had to choose between obtaining a specified amount of money paid out with a given probability or playing it safe with a lower amount of money paid out for sure. The riskier the decision, the higher the possible prize &#8212; but also the risk of getting nothing.<\/p>\n<p><strong>Riskier behavior remains unnoticed<\/strong><\/p>\n<p>While a single sleepless night had no effect on risk-seeking, 11 of 14 of the subjects behaved significantly and increasingly riskier as the week of a reduced sleep duration went on. An additional finding is particularly alarming: The students assess their risk-taking behavior to be the same as under regular sleep conditions. &#8220;<strong>We therefore do not notice ourselves that we are acting riskier when suffering from a lack of sleep<\/strong>,&#8221; emphasizes Christian Baumann, professor of neurology and the head of the Clinical Research Priority Programs (CRPP) &#8220;Sleep and Health&#8221; at UZH. According to the authors of the study, we should therefore all strive for a sufficient sleep duration &#8212; especially political and economic leaders who make wide-reaching decisions daily. &#8220;The good news is,&#8221; Baumann says, &#8220;that, in the high-powered world of managers, getting enough sleep is increasingly being seen as desirable.&#8221;<\/p>\n<p><strong>Lack of recovery in important regions of the brain<\/strong><\/p>\n<p>For the first time, the researchers have proven that a low depth of sleep in the right prefrontal cortex is directly connected with higher risk-seeking behavior. This part of the cerebral cortex has already been associated with risk-taking behavior in earlier studies. &#8220;We assume that behavioral changes occur for anatomical-functional reasons to some extent as a result of the right prefrontal cortex not being able to recover properly due to a chronic lack of sleep,&#8221; Baumann concludes.<\/p>\n<\/div>\n<\/blockquote>\n<!-- AddThis Advanced Settings generic via filter on the_content --><!-- AddThis Share Buttons generic via filter on the_content -->","protected":false},"excerpt":{"rendered":"<p>From the University of Z\u00fcrich press release: Young adults have a natural sleep requirement of about 9 hours a day on average, older adults 7.5 hours.
