Purpose Excessive daytime sleepiness is a common symptom in obstructive sleep apnea (OSA). Previous studies have showed that excessive daytime sleepiness is associated with some individual components of metabolic syndrome. We performed a large cross-sectional study to explore the relationship between excessive daytime sleepiness and metabolic syndrome in male OSA patients. Methods A total of ...

Driver sleepiness is a major contributor to severe crashes and fatalities on our roads. Many people continue to drive despite being aware of feeling tired. Prevention relies heavily on education campaigns as it is difficult to police driver sleepiness. The video sharing social media site YouTube is extremely popular, particularly with at risk driver demographics. Content and popularity of uploa...

PURPOSE Excessive daytime sleepiness is highly prevalent in the general population, is the hallmark of narcolepsy, and is linked to significant morbidity. Clinical assessment of sleepiness remains challenging and the common objective multiple sleep latency test (MSLT) and subjective Epworth sleepiness scale (ESS) methods correlate poorly. We examined the relative utility of pupillary unrest ind...

Objective sleepiness evaluation is essential for the effect analysis of countermeasures for driver sleepiness, such as in-car stimulants. Furthermore, measuring drivers’ sleepiness in simulator studies also becomes important when investigating causes for task-related sleepiness, for example driving on monotonous routes, which requires little driver engagement. To evaluate driver sleepiness and ...

background and objectives: today, 24-hours work is an unavoidable component in several industries. night-work is an imperative situation for an important part of workforces. shift-working is called to work at hours out of usual day-work time (7:00 am to 6:00 pm). the present study was a cross sectional descriptive-analytic research, and was carried out in order to investigate sleepiness and cha...

INTRODUCTION Sleepiness in students has an impact on their learning, focus and memory. Sleepiness is caused by multiple factors. Therefore, our objective was to estimate the frequency of sleepiness in Peruvian students and assess its relation to lifestyle and sleep habits. METHODS Cross-sectional study conducted on first through fifth year secondary students. The Spanish version of the pediat...

Subjective sleepiness is part of the system controlling the decision to go to sleep in humans. Extended periods of waking lead to increased sleepiness, as well as to changes in cortical electroencephalogram (EEG) during waking. We investigated the association of sleepiness and awake EEG spectra during 40 h of wakefulness using multi-electrode EEG recordings for full coverage of the scalp. We fo...

Investigators in previous research have indicated that subjective measures of sleepiness may separate into stateand behavior-based dimensions; however, researchers have not examined this under sleep deprivation conditions. The authors’ purpose in this study was to examine several measures of subjective sleepiness under sleep deprivation conditions following completion of various tasks. Fourteen...
