Anyone who has ever put a baby in bed, gently rocking, or who has carried it Paraguay Hammock He knows rocking promotes sleep. But why?

To understand these phenomena and gaming mechanisms, researchers from the Universities of Geneva (UNIGE), Lausanne (UNIL) and Geneva University Hospitals (HUG) conducted two studies showing that slow and repetitive movement at night modulates the activity of brain waves. As a result, balancing not only contributes to deeper sleep, but also helps to strengthen the memory that is consolidated in some sleep stages.

Scientists have shown in previous studies that rocking for 45 minutes helps people fall asleep more fast and more deep. But what are the consequences of this slow motion in the brain? The researchers conducted a new study and their results are described in detail Current Biology.

Paraguay's hammock power

Study by Laurence Bayer, researcher at UNIGE Medical School, and HUG Sleep Medicine Center, in Geneva, and Sophie Schwartz, Professor at the Department of Science at the Faculty of Medicine, Faculty of Health. UNIGE, is studying the effects of continuous balancing on sleep and brain waves that characterize it.

A total of 18 healthy young adults spent two nights in a sleeping medical center, one in a moving bed and the other in the same bed, but in a stationary position. "Good night sleep is fast falling asleep and sleep all night"Says Laurence Bayer." However, we noticed that our participants, though sleeping well in both cases, fell asleep faster. In addition, they had longer periods of deep sleep and fewer microwave alarms, often associated with poor sleep quality. "

Deep sleep enhancement by balancing is a direct effect of brain waves during sleep. Continuous rolling This enables synchronization of neuronal activity, which plays an important role in the strengthening of sleep, but also in memory.a. "To see if this effect also affects memory, we sent our participants to memory tests: in the afternoon they had to learn the words of couples, and in the morning when they woke up, remembered them," says Aurore Perrault, a researcher at the Faculty of Medicine. from UNIGE. "And here the balancing also turned out to be beneficial: the test results were much better after the night, than after a quiet night," he added.
