Abstract
The U.S. Navy Recruit Training Command in Great Lakes, Illinois is responsible for training all enlisted personnel, about 50,000 young recruits per year. Demands on these recruits are steep and there is concern that by restricting the amount of sleep, learning efficiency is adversely affected. There are additional concerns about possible increases in attrition and reductions in morale due to sleep deprivation. Every minute of the 63 day training schedule is closely managed, including the time allocated for sleep. Within recent years, the designated sleep regimens have changed considerably from 6 hours of sleep (2200 to 0400) in 2001 to 8 hours of sleep (2200 to 0600) as of June 2002. In the months of April through June, 2002, we collected data on the quantity and quality of sleep received by 31 volunteer recruits in two 8 hour conditions: 2100 to 0500 and 2200 to 0600. Using wrist activity monitors, we calculated the actual amount of sleep and contrasted it with the expected amount for each participant. Additionally, comparisons were made between bedtimes (2100 vs. 2200), gender, different training divisions, nights with and without sleep disruptions (due to watch standing and other factors), and different days of the week.
