A new study suggests that while a body takes a short nap, short of deep sleep, the right-brain is actively performing tasks and becomes more engaged than normal.
Researchers expected that because 87% of the participants were right-handed, the left brain would become more integrated, since right-handed individuals normally are. However, the results were consistent across all participants – the right-brain was more integrated. The right-brain is considered to be the hemisphere associated with creativity, such as visualization and imagination. This evidence suggests that power naps may increase creativity, as well as performing necessary functions such as memory consolidation.
This study, while preliminary, offers yet more insight into the importance of sleep for living a healthy, fulfilled life. The brains cognitive abilities are just waiting to be unleashed if given ample rest.
