Although sleep and exercise may seem to be mediated by completely different physiological mechanisms, there is growing evidence for clinically important relationships between these two behaviors. It is known that passive body heating facilitates the nocturnal sleep of healthy elderly people with insomnia. This finding supports the hypothesis that changes in body temperature trigger somnogenic b...

The present study was designed to test the impact of rotation and timing of shifts on work--home conflict, job attitudes, health and absenteeism among the military police. A total of 3122 employees participated in the study.

Circadian rhythms show universally a 24-h oscillation pattern in metabolic, physiological and behavioral functions of almost all species. This pattern is due to a fundamental adaptation to the rotation of Earth around its own axis. Molecular mechanisms of generation of circadian rhythms organize a biochemical network in suprachiasmatic nucleus and peripheral tissues, building cell autonomous cl...

Abstract Introduction Watchfloors provide around-the-clock information, intelligence, and technical support to the U.S. military. Active-duty service members (ADSMs) working on these 24/7 watchfloors stand watches include night shifts and/or frequent shift rotations. Tailoring shiftwork schedules optimize individual sleep patterns may reduce negative effects of shiftwork. The purpose this study...
