Cognitive performance is negatively affected by less than seven hours, but more than nine hours of sleep, according to researchers at University College London (UCL). It affects the visual memory and negatively affects the reaction time.
Almost 400,000 participants in the UK Biobank database, as well as international project information from the International Genomics of Alzheimer’s Disease Project (IGAP) investigating Alzheimer’s disease, were analyzed by researchers. They were looking for a connection between sleep and cognitive functions and dementia.
BY THE RESULTS, THOSE WHO WAS LESS THAN TWO WEEKS OF DAY WEEK, THERE ARE NO LESS THAN 5 YEARS OF SEVERAL FAULTS IN THE VISUAL MEMORY TEST. WHO HAVE DAYS MORE THAN HALF-TIME CLOTHING, THERE ARE MORE ERRORS (9 MILLION MORE). THE REACTION YOURSELF WAS LESS THAN ONE DAY WITH ALL PLUS CLOCK.
As a result, a healthy adult should sleep 7-9 hours, said Victoria Garfield, a senior researcher at the UCL, that is, if someone can keep it, there may be positive benefits for cognitive health.
