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 amphibious assault ship Essex. They led a study Markwald said could someday help commanders spot when crew members are reaching dangerous fatigue levels that might interfere with their duties.

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 question of whether sleep-deprivation is a problem,” said Kevin “Bud” Couch, the San Diego-based director of operational safety for the Navy’s surface fleet. “It’s what do we do about it?”

Some combat experiences like ambushes or killing a civilian more closely linked to suicide, study finds February 19 Personnel Specialist Seaman Jenesis Fabian ties a yellow ribbon around a tree at Mayport Memorial Park in recognition of Suicide Awareness Month.(MC3 Alana Langdon/Navy) Though research has found that most service members who die by suicide have never deployed to combat, that doesn’t show the whole picture. A recent military study found that some combat experiences, especially when coupled with PTSD or depression, are a risk factor in suicide attempts. Combat in general didn’t translate to more attempts, the Naval Health Research Center found, but high-intensity situations like ambushes, or inadvertently killing a non-combatant, were more linked to suicidal ideation.
