A study just published in the journal Current Biology won’t surprise any blissfully-snoozing babies out there. It seems that being rocked really does help you sleep better.
On different evenings, researchers from The University of Geneva monitored the sleep of healthy adults both in a stationary bed and in a rocking bed that gently swayed through the night.
Results showed that, when they slept in the swaying bed, the participants tended to nod off more quickly, had deeper sleep and stayed asleep for longer with less awakenings.
After a rocking night’s sleep they also performed better in memory tests.
Rocking appears to change patterns of brainwaves associated with sleep and memory.
