To assess sleep inertia following 10-min and 30-min naps during a simulated night shift. Thirty-one healthy adults (aged 21–35 y; 18 females) participated in 3-day laboratory study that included one baseline (BL) (22:00–07:00) experimental involving randomization to either: total deprivation (NO-NAP), nap (10-NAP) or (30-NAP). Nap opportunities ended at 04:00. A 3-min psychomotor vigilance task (PVT-B), digit-symbol substitution (DSST), fatigue scale, sleepiness self-rated performance scale...
Innovative, pedagogically informed instructional design is instrumental in increasing student engagement and improving learning outcomes online environments. Interactive resources provide students with the opportunity to engage content a more personalised manner. H5P (HTML 5 Package) collaborative platform that allows developers create interactive has been regularly used education settings. Some evidence suggests using courses could lead greater engagement. However, date, there little...
Shiftworkers report eating during the night when body is primed to sleep. This study investigated impact of altering food timing on subjective responses. Healthy participants (
Introduction: Two of the most ubiquitous fatigue countermeasures used by shift-working nurses are napping and caffeine. This mixed-methods case study investigated ways midwives utilised caffeine to cope with shift work, associated sleep, physical health psychological outcomes.Materials Methods: N = 130 Australian (mean age 44 years, range 21–67, 115F, 15M) completed Standard Shiftwork Index. A sub-set 22 an in-depth interview.Results: Nearly 70% participants reported napping. Those who...
Shift work is a risk factor for chronic diseases such as Type 2 diabetes. Food choice may play role, however simply eating at night when the body primed sleep have implications health. This study examined impact of consuming big versus small snack on glucose metabolism. N = 31 healthy subjects (21-35 y; 18 F) participated in simulated nightshift laboratory that included one baseline (22:00 h-07:00 h) and awake with allocation to either (2100 kJ) or (840 group. The was consumed between...
Background: Cyberbullying and nighttime phone use are independently detrimental to sleep psychological wellbeing, but whether in combination they might be more disruptive remains unknown. Methods: Students aged 7–19 years (N = 53,734) completed a survey measuring duration, use, cyberbullying, distress. Results: Across stratification variables of gender (F/M) age group (primary/secondary-school-aged children), bivariate ordered probit regression revealed that being cyberbullied were...
Altering meal timing could improve cognition, alertness, and thus safety during the nightshift. This study investigated differential impact of consuming a meal, snack, or not eating nightshift on cognitive performance (ANZCTR12615001107516). 39 healthy participants (59% male, age mean±SD: 24.5 ± 5.0y) completed 7-day laboratory underwent four simulated nightshifts. Participants were randomly allocated to: Meal at Night (MN; n= 12), Snack (SN; n = 13) No Eating (NE; 14). At 00:30 h, MN...
Short naps on night shift are recommended in some industries. There is a paucity of evidence to verify the sustained recovery benefits short last few hours shift. Therefore, current study aimed investigate 30 and 10-min nap opportunities during simulated Thirty-one healthy participants (18F, 21–35 y) completed 3-day, between-groups laboratory with one baseline (22:00–07:00 h time bed), followed by awake (time from 07:00 day two through 10:00 three) random allocation to: opportunity ending at...
Consuming coffee immediately prior to a nap, known as caffeine-nap, has been shown improve alertness during the day, but it is unknown whether caffeine-nap effective at reducing sleep inertia night. A simulated shiftwork cross-over laboratory study was conducted whereby participants (N = 6, 4 F, 21–36y) consumed 200 mg of caffeine, or decaffeinated (placebo), 30 min nap opportunity 03:30 h. Compared placebo, resulted in improved vigilant attention and subjective fatigue 45 post-nap...
Night-shift work causes circadian misalignment and impairs glucose metabolism. We hypothesise that food intake during night shifts may contribute to this phenomenon.
Sleep inertia is a safety concern for shift workers returning to work soon after waking up. Split duty schedules offer an alternative longer periods, but introduce additional wake-ups and may therefore increase risk of sleep inertia. This study investigated across split schedule. Sixteen participants (age range 21–36 years; 10 females) participated in 9-day laboratory with two baseline nights (10 h time bed, [TIB]), four 24-h periods 6-h on/6-h off schedule (5-h TIB period; 10-h per 24 h)...
Flight attendants experience circadian misalignment and disrupted sleep eating patterns. This survey study examined working time, sleep, frequency in a sample (n=21, 4 males, 17 females) of Australian flight (mean age=41.8 yr, SD=12.0 mean BMI=23.8 kg/m2, SD=4.1 kg/m2). Respondents indicated frequencies snack, meal, caffeine consumption during their last shift. Reported duration on workdays (mean=4.6 h, SD=1.9 h) was significantly lower than days off (M=7.2 SD=1.2 p<0.001), perceived need...
Abstract Higher and lower levels of alertness typically lead to a leftward rightward bias in attention, respectively. This relationship between spatial attention potentially has major implications for health safety. The current study examined under simulated shiftworking conditions. Nineteen healthy right-handed participants (M = 24.6 ± 5.3 years, 11 males) completed seven-day laboratory based shiftwork study. Measures (Stanford Sleepiness Scale Psychomotor Vigilance Task) (Landmark Task...
This study investigated the reliability and factor structure of General Health Questionnaire‐12 (GHQ‐12) in children adolescents examined whether GHQ‐12 is sensitive to expected men...
Objective The commute home following a night shift is associated with an increased risk for accidents. This study investigated the relationship between food intake during and simulated driving performance post-shift. Methods Healthy non-shift working males (N=23) females (N=16), aged 18–39 years (mean 24.5, standard deviation 5.0, years) participated in seven-day laboratory underwent four shifts. Participants were randomly allocated to one of three conditions: meal at (N=12; 7 males), snack...
Many shiftworkers take short naps on nightshift to reduce the detrimental effects of sleep loss. However, inertia resulting from napping can have deleterious performance. Caffeine may be a useful countermeasure for inertia. This study examined effectiveness 200mg caffeine gum in reducing following 30min nighttime nap opportunity at 0200h. N=5 subjects (3F, M=22.2±SD3.8y) took part 2-day laboratory study, with randomised double-blind, placebo-controlled crossover design one-week abstaining...
