Navy Okays Changes to Submariner's Sleep Patterns
With no sunlight to set day apart from night on a submarine, the U.S. Navy for decades has staggered sailors' working hours on schedules with little resemblance to life above the ocean's surface.
Research by a Navy laboratory in Groton, Conn. is now leading to changes for the undersea fleet. Military scientists concluded submarine sailors, who traditionally begin a new workday every 18 hours, show less fatigue on a 24-hour schedule, and the Navy has endorsed the findings for any skippers who want to make the switch.
The first submarine to try the new schedule on a full deployment was the USS Scranton, led by Cmdr. Seth Burton, a cancer survivor. He said the illness he experienced as a junior officer helped convince him of the health benefits of keeping a sleep pattern in line with the body's natural rhythm.
"I know that there's lots of medical side effects to just not having a good, regular sleep pattern," said Burton, 41, of Huntsville, Ala.
