Background: It has been shown that endurance performance after one night of sleep deprivation is not compromised despite the feeling of fatigue and that, in contrast, performance in the heat deteriorates even though people may feel good. However, it is essentially unknown how the estimation of performance capabilities relate to actual...

Objective: The epidemiological evidence for the association between sleep duration and obesity in the elderly is inconsistent and has not been investigated with objective measures. Furthermore, the role of sleep fragmentation in this relationship is unknown. Our aim was to investigate the association of sleep measures with body mass index (BMI)...

Introduction: During sustained operations, a combined use of a hypnotic to induce sleep under difficult circumstances and a psychostimulant to improve performance and alertness during night-shift work or after sleep deprivation may be necessary. This study was conducted to evaluate the effect of modafinil and caffeine as countermeasures to...

In two experiments, 64 male students worked almost continuously for 20 hours without sleep, under varying social conditions. In experiment 1, participants worked either individually or as a group. As hypothesized, performance deteriorated over time, especially in the group condition, which allowed participants to loaf. In experiment 2, all...

When people have to work clock round for longer periods of time, fatigue can have strong negative effects on the task performance. Group processes in the unit can partly compensate fatigue effects. From studies carried out by TNO it became clear that people keep performing better when there is someone present during task performance, instead of...
