New research in Military Psychology indicates that National Guard service members suffer reductions in sleep as they transition from civilian to military duty, which could harm their effectiveness, reports PsyPost.

“As a former public health officer and chief nurse (Lt Col, retired 2012) for the Air National Guard, my interest in the health of the medical personnel evolved after several critical exercises that involved severe sleep deprivation of all medical and non-medical disaster response team service members,” said study author Denise A. Smart, an associate professor at Washington State University.
