The purpose of this study was to compare the effects of two commonly utilized sleepiness countermeasures: a nap break and an active rest break. The effects of the countermeasures were evaluated by physiological (EEG), subjective, and driving performance measures. Participants completed 2 h of simulated driving, followed by a 15-min nap break or a 15-min active rest break, then completed the final hour of simulated driving. The nap break reduced EEG and subjective sleepiness. The active rest break did not reduce EEG sleepiness, with sleepiness levels eventually increasing, and resulted in an immediate reduction of subjective sleepiness. No difference was found between the two breaks for the driving performance measure. The immediate reduction of subjective sleepiness after the active rest break could leave drivers with erroneous perceptions of their sleepiness, particularly with increases of physiological sleepiness after the break.

“…However, the MDC scores used in this investigation were generated from pretest scores that could have been at least 2 weeks apart, compared with the pretest-to-posttest assessments completed within about 10 minutes of each other. Given the fact that both sleep patterns 33 and time of day can influence postural control, 34 we are hesitant to refute our findings and large effects on the basis of the calculated MDC scores but believe it is important to include such data in the spirit of full disclosure.…”

“…Vigilance reflects the level of CNSs activation and the varied levels can be estimated on a continuum between wake and sleep (vice versa for sleepiness) [25]. It has been shown that postural control is modified by the level of vigilance or sleepiness [4, 6, 17, 22, 23, 26–28]. Since maintaining balance requires continuous integration of different sensory inputs, it has been proposed that vigilance impairment affects the processes of these integrations at the CNS level and, in parallel, also affects the processes underlying efficient adjustments of movements involved in postural sway regulation [17, 26, 27].…”

The underlying processes responsible for the differences between morning and afternoon measurements of postural control have not yet been clearly identified. This study was conducted to specify the role played by vestibular, visual, and somatosensory inputs in postural balance and their link with the diurnal fluctuations of body temperature and vigilance level. Nineteen healthy male subjects (mean age: 20.5 ± 1.3 years) participated in test sessions at 6:00 a.m. and 6:00 p.m. after a normal night's sleep. Temperature was measured before the subjects completed a sign cancellation test and a postural control evaluation with eyes both open and closed. Our results confirmed that postural control improved throughout the day according to the circadian rhythm of body temperature and sleepiness/vigilance. The path length as a function of surface ratio increased between 6:00 a.m. and 6:00 p.m. This is due to a decrease in the centre-of-pressure surface area, which is associated with an increase in path length. Romberg's index did not change throughout the day; however, the spectral analysis (fast Fourier transform) of the centre-of-pressure excursions (in anteroposterior and mediolateral directions) indicated that diurnal fluctuations in postural control may occur via changes in the different processes responsible for readjustment via muscle contractions.
