Why sleep pleasantly when sleeping in a hammock

In Japan, there are relations of housing circumstances and climate, not too familiarhammockHowever, there are also people who have experienced at the travel destination or somehow admired. Research has revealed that the slow "shaking" brought about by the hammock is very effective for sleeping.

Why Hammocks Make Sleep Easier, Deeper: Shots - Health Blog: NPR

According to the research that Swiss scientists have made, mild bring hammock "swing" is, on which it is possible to fall quickly asleep than sleep in a bed, so the more deep sleep. And changes in the activity of the brain "shaking" will bring it with might be a new help for insomnia.


In an experiment conducted by scientists, we prepared a bed that swayed slowly enough that it took 4 seconds to reach from end to end. Sophie Schwartz, a neuroscientist at the University of Geneva, who led the research, said, "This" shaking "is very calm and smooth, it's more calm than when the mother shakes the baby and is much slower than the cuckoo clock It is speed. "

This is the bed we used for the experiment.


We asked the adults of the subjects to take a nap for 45 minutes each once on the "swinging bed" and the usual "stationary bed" and measured the activity of the brain with the electrodes attached to the scalp. Then, the subject who fell asleep quickly when he fell asleep in the "swinging bed" fell asleep quickly, but this result seems not to be surprised so much as it was the scientists' imagination. However, looking at the result of the brain activity measured, there was a big difference between the two, so it was surprised that the truly scientists were surprised.

Sleep is a pattern of electroencephalogram and eye movements with 4 stagesREM sleepWe call stages I to IV collectively as non-REM sleep (state of deep sleep). Sleeping brain waves called "sleep spindle waves (spindles)" appear at stage II, but subjects who slept in "shaking bed" seemed to have increased in stage II time.

"Sleep spindle wave" is related to gentle sleep in noisy environments such as noise, and it is thought that it is considered as a sign that the brain is trying to calm sleeping people. It is also important for the ability to memorize new information and reconstruction of memory. In addition, there was an increase in slow oscillation related to resilient high-quality sleeping, and the idea of ​​"becoming easy to fall asleep", which was previously known empirically, became more firm.

"What we tried to find was a scientific proof that" the tremors invite sleep, "said Michael, a professor of neuroscience who conducted research with Schwartz. And it says that "I did not expect at all" as a result of a large change in the measured brain waves. In addition, the results of this experiment are the academic journals "Current biologyIt was announced at.

"Shaking" changed the brain and in the future we need to test this experiment with people with stroke and other brain injuries, "Schwartz said, and general sleep disorders such as insomnia It seems that we will also investigate the effect of 'shaking' on sleep for a long time as it may be of help.
