CNN —Taking daytime naps may help maintain brain health as we age, according to a new study. The results show “a small but significant increase in brain volume in people who have a genetic signature associated with taking daytime naps,” she told the Science Media Centre. “Even with those limitations, this study is interesting because it adds to the data indicating that sleep is important for brain health,” she said.

Grandner directs the Behavioral Sleep Medicine Clinic at the Banner-University Medical Center in Tucson, Arizona, and was not involved in the study.
