The WRAIR Sleep Research Center (SRC), part of the Behavioral Biology Branch, is the Department of Defense's premier sleep research facility. WRAIR has conducted sleep studies since the 1950s to characterize the acute performance and physiological impacts of sleep loss. The SRC develops strategies (sleep banking) and technologies (sleep trackers) for monitoring, preventing, and reversing the harmful effects of sleep loss, stress, and fatigue to enhance Soldier operational judgment and decision-making. The sleep research suites offer the infrastructure to conduct sleep deprivation, sleep extension, and intervention studies 24 hours a day.
