Children's sleep behaviors linked to gray matter volume with implications for academic performance, IQ

By ITS Education Asia

Emily Henderson of the News Medical Life Sciences reports that it is now scientifically proven that children who sleep better (that is, those who wake up less during night) and those who wake up earlier have more grey matter in their brains (specifically, in eight cortical regions and in the hippocampus), perform better academically, and have a higher level of intelligence (IQ).

This has been demonstrated by scientists from the Sport and Health University Research Institute (iMUDS) and the Mind, Brain and Behaviour Research Centre (CIMCYC)—both part of the University of Granada (UGR). The scientists are collaborating in the ‘ActiveBrains’ study led by researcher Francisco Ortega
