A sleep deficit can increase the propensity for risky decisions. Such conclusions were made by scientists of the University of Zurich, according to Naked Science.

Scientists conducted the study, which involved 14 male students aged 18 to 28 years. Under the terms of the experiment, the participants during the week slept for five hours a day. Two weeks later, they were forced to stay awake continuously for 40 hours.

Before the beginning of experiments and after each stage, the participants were tested, disclosing the risk appetite. Twice a day students were offered to choose to obtain a small amount of guaranteed money or take the risk and in case of success to much more money.

A five-hour sleep for one day did not affect risk appetite, however, the participants ‘ behavior changed after a week of lack of sleep: 11 of 14 participants took significantly riskier decisions. Moreover, these students believed that their risk appetite remains the same.

Scientists emphasize that the underestimation of changes in one’s own behavior is one of the dangerous consequences of sleep deficit.

The researchers concluded that risky behavior nedosypayuschih people connected with the activity of the prefrontal cortex, which is responsible for the planning and decision-making. Scientists suggest that lack of sleep does not allow this area to fully recover.

March 17, 2017, the doctors said that a good night’s sleep is the most effective, easiest and cheapest way to improve the health and well-being of society as a whole.
