(Jack Guy/ CNN News) — Taking daytime naps may help maintain brain health as we age, according to a new study. However, prior research has shown that excess napping can also be harmful.
Habitual napping was linked with larger total brain volume, which is associated with a lower risk of dementia and other diseases, according to researchers from University College London (UCL) and the University of the Republic of Uruguay.
On average, the difference in brain volume between nappers and non-nappers was equivalent to 2.5 to 6.5 years of aging, researchers said.
“Our findings suggest that, for some people, short daytime naps may be a part of the puzzle that could help preserve the health of the brain as we get older,” said senior author Victoria Garfield, a senior research fellow at UCL, in a statement. (…)
