A popular spot to relax in these summer months are in the comfort of a hammock, rocking in the summer breeze. A recent study shows that a comfy hammock does not only put you in a tropical state of mind, but also in a deep state of sleep. This study published in Current Biology found that people fell asleep faster and into a deeper sleep than they would in a stationary bed. Twelve male volunteers were subjects of this study and were asked to take naps in a hammock. One nap consisted of a rocking hammock and during the other nap the hammock remained still.
After looking into the subject’s brain activity, it was found that the rocking motion of the hammock was the reason for the better sleep of the study participants. The researchers are still looking into why the rocking motion is conducive to better sleep and have a second study already in the works. They recognized that babies almost always benefit from motion to help them sleep, but the connection of motion and sleep in regards to adults has not been studied in depth.
