Performance impairment during four days partial sleep deprivation compared with the acute effects of alcohol and hypoxia

Sleep-Related Behaviors and Beliefs Associated With Race/Ethnicity in Women

“…Groups differed in strategies for coping with difficulties falling asleep, in that black participants were more likely to drink alcohol (which is more likely to exacerbate problems rather than ameliorate them 33,34 ) and do something in bed (which is often a maladaptive coping strategy that places them at increased risk of developing psychophysiological insomnia 4 ). Additionally, black participants were more likely to report getting up to start their day, which may reflect an inability to return to sleep 35 or, conversely, may reflect the adaptive coping strategy of stimulus control.…”

Effects of nocturnal aircraft noise on cognitive performance in the following morning: dose–response relationships in laboratory and field

“…Most probably, nocturnal aircraft noise exposure led to a moderate partial sleep deprivation which affects daytime performance (Basner et al 2006a). Using the impact of cumulative partial sleep deprivation or acute effects of alcohol exposure on PVT as scaling of values (Elmenhorst et al 2009), nocturnal aircraft noise exposure had a considerably smaller influence on reaction time. Reaction time impairments caused by four nights of 5-h sleep ranged between 5.7 and 8.8 ms; breath alcohol concentration of 0.6% led to reaction time extensions of about 13 ms.…”

Working in our sleep

“…Harrison and Horne (1999) found that missing a single night of sleep led to decrements in innovative thinking, and similarly Nilsson et al (2005) found that missing one night of sleep leads to decrements in executive functioning. Elmenhorst et al (2009) found that four consecutive nights of 5 hours of sleep per night leads to decrements in a cognitive task equivalent to a blood alcohol content of 0.6%. Barnes and Wagner (2009) found that a 40-minute decrement in sleep was associated with a 5.6% spike in work injuries.…”
