Sleep deprivation far more harmful than thought: Study
India TodaySleep deprivation is much more harmful to humans than previously thought, according to one of the largest sleep studies to date. The study, published in the Journal of Experimental Psychology: General, is the first to assess how sleep deprivation impacts place keeping -- the ability to complete a series of steps without losing one's place, despite potential interruptions. "Our research showed that sleep deprivation doubles the odds of making place keeping errors and triples the number of lapses in attention, which is startling," said Kimberly Fenn from Michigan State University in the US. "Our findings debunk a common theory that suggests that attention is the only cognitive function affected by sleep deprivation," said Michelle Stepan, MSU doctoral candidate. However, the results suggest that completing an activity that requires following multiple steps, such as a doctor completing a medical procedure, is much riskier under conditions of sleep deprivation.
