Description

rocking bed {ROCKING BED}

The present disclosure relates to a bed, and specifically to a rocking bed.

In modern society, various sleep disorders including insomnia are emerging as serious social problems. Complications caused by sleep disorders are also showing an explosive increase, and accordingly, the quality of life of individuals and the cost of solving various social problems and social problems are also increasing exponentially.

Orally administered sleeping pills or sleep inducing agents have been suggested as a way to solve these sleep disorders. However, as is well known, most sleeping pills can cause from mild side effects such as dizziness and headache due to central nervous system depressant action to serious side effects such as memory loss and sleepwalking.

On the other hand, according to the research paper “Rocking synchronizes brain waves during a short nap (published on June 21, 2011, author: Sophie Schwartz et al.)” of the Sleep Research Center of Geneva University Hospital, Switzerland, sleep in a hammock-like device In this case, it is said that the elevation can be reached faster than usual. In addition, it is said that effects such as reduction of wake-up time, increase of deep sleep and reduction of light sleep, etc. occur.

However, a device such as a hammock is only a device for sleeping, such as a short nap, and maintaining sleep for a long time may cause back pain and the like.

Accordingly, there is a demand for a comfortable bed capable of improving sleep-related disorders.
