It wasn’t just that the childhood trick made adults fall asleep easier. The research also found that they had better rest and longer sleep times. Researchers seem to think that the rocking motion creates some kind of brain-wave synchronization that leads to deeper and better quality sleep. In fact, according to one of the researchers, Michel Muhlethaler, the fact that brain-wave synchronization led to deeper sleep was a total surprise (via NPR). “It’s not just you go faster to sleep, but also while you sleep, your sleep is deeper. … We did not expect that. There was nothing in the literature to tell us that this would be the case,” shared Muhlethaler.
Furthermore, the study revealed that participants had fewer “micro-wakes” while being rocked in their beds, per Medical News Today.
You know how, sometimes, you roll around and wake up for some reason in the middle of the night and struggle to get back to sleep? Well turns out, sleeping on an adult-sized rocking bed might fix that too. And there’s more.
