Negative effects of sleep restriction may linger after 1 night of recovery sleep

experiment. Fifty-seven percent of participants were African-American. Following two baseline nights of 10 hours time in bed, 142 participants were randomized to the sleep restriction protocol of four hours in bed from 4 a.m. to 8 a.m. for five consecutive nights. Then they were randomized to one of six doses of recovery sleep ranging from zero hours to 10 hours in bed for one night. The other 17 participants were randomized to a control group and spent 10 hours in bed on all nights.

Beginning at 8 a.m. each day, participants completed 30-minute computerized neurobehavioral assessments every two hours during scheduled periods of wakefulness. Assessments included a 10-minute Psychomotor Vigilance Test and the Karolinska Sleepiness Scale. A modified Maintenance of Wakefulness Test also was conducted at baseline, on the fifth day of sleep restriction and on the recovery day.

Mean total sleep time dropped from 8.47 hours at baseline to 3.72 hours on the first night of sleep restriction. Relative to the control group, sleep restriction degraded all neurobehavioral functions across the five days of sleep loss. One night of recovery sleep then improved all neurobehavioral outcomes as sleep doses increased. However, lapses of attention, subjective sleepiness, reaction times and fatigue scores all remained elevated above baseline levels in the 27 participants who spent 10 hours in bed on the recovery night.

"The additional hour or two of sleep in the morning after a period of chronic partial sleep loss has genuine benefits for continued recovery of behavioral alertness," said Dinges. "The bottom line is that adequate recovery sleep duration is important for coping with the effects of chronic sleep restriction on the brain."

Extrapolations estimated that at least 10 hours of recovery sleep would be necessary for sleep-restricted participants to match the functional levels of the well-rested control group. However, the authors not
