The new devices, called “wearables,” are part of a new push to develop a “digital real-time fatigue monitoring and management capability for the fleet” that can be used to optimize watch-bill scheduling and staffing decisions based on sailors’ fatigue risk.
GROTON, Conn. Our bodies respond to daily light-dark cycles to maintain our circadian rhythms: our internal clocks that tell us we should be awake during the day and asleep at night. Researchers at the Naval Submarine Medical Research Laboratory (NSMRL) are investigating ways to maintain those rhythms in submariners, who cannot rely on natural sunlight or external environmental cues to stay on track. When we wake up, when we go to sleep, when we are hungry, when we fall into a daily afternoon slumpâ¦all these processes are regulated by our circadian rhythms (also called circadian clocks)....

Why 300 Sailors and Marines Deployed on an Amphibious Ship with Smart Rings Lt. Xavier Pierce from Reaford, N.C., puts on a health-monitoring ring as part of the Crew Readiness, Endurance, and Watch Standing (CREW) study aboard Wasp-class amphibious assault ship USS Essex. (U.S. Navy/Mass Communication Specialist 3rd Class Isaak Martinez) 14 Apr 2021 Researchers who set out to study fatigue on a Navy warship found out firsthand that getting good rest while underway is not easy. Rachel Markwald, a sleep physiologist with the Naval Health Research Center, and her team spent two weeks aboard the...
Print Sleep has often been considered the enemy of America’s armed forces, something to be conquered with caffeine, prescription drugs, or willpower. Now that may be changing. The Pentagon released a report last month calling for a “culture shift” that recognizes adequate sleep as “a key component of readiness,” not an impediment. It recommended improvements in work schedules and battle plans, as well as the use of specialists known as “sleep trainers,” wearable sleep trackers, and behavioral counseling to ensure service members get enough shut-eye. “It’s no longer a questi...
