On nan "stop snoozing" broadside of nan research, American slumber intelligence Dr Rebecca Robbins suggests nan snooze siren whitethorn really costs america sleep.

"That first siren whitethorn interrupt captious stages of sleep, and thing that you mightiness beryllium capable to get aft hitting nan snooze siren is astir apt going to beryllium debased value and fragmented sleep," said Robbins, an subordinate intelligence for nan Division of Sleep and Circadian Disorders astatine Brigham and Women's Hospital, successful nan north-east US.

As we sleep, nan encephalon cycles done different stages of neurological activity and nan 2nd half of nan nighttime is dominated by accelerated oculus activity (REM) sleep, erstwhile astir of our dreaming is thought to return place. It's an important slumber shape for our cognitive usability and representation consolidation, said Robbins, who is besides an adjunct professor of medicine astatine Brigham and Women's Hospital.

"When you property nan snooze button, particularly for conscionable a fewer minutes astatine a time, you're not apt to return to that REM stage," Robbins said.
