Six hours of sleep may sound fulfilling but in the long run, it could indicate sleep deprivation, revealed a new study.
The study published in the journal SLEEP
found that not managing to get more than six hours of sleep daily may lead to sleep deprivation and is as bad as not sleeping at all.
‘Taking only six hours of shut-eye was as bad as not sleeping for two days straight.’
A team of researchers at the University of Pennsylvania School of Medicine analyzed 48 individuals who were divided into four groups namely, eight hours, six hours, four hours and no hours of sleep. Their cognitive functions were analyzed every two hours they were awake.
At the end of the 15-day study, they found that participants who got eight hours of sleep regularly performed the best and those who slept for four hours were the worst.
At first, participants who slept for six hours every day were feeling fresh and performed better for some days, but in the long run, their cognitive performance declined and matched to that of persons who did not sleep for two days straight.
The study suggested that sleeping hours depend on each individual but managing to get more than six hours will benefit people and protect against sleep deprivation.
