“…Following data extraction 8 papers were excluded: 3 for having no interpretable data (Iverson, 2004;Ueda et al, 2005;Wolff, III et al, 1985), two conference abstracts with insufficient data (Deoras et al, 2010;Kelly et al, 2009), two for inappropriate comparisons (Lemke et al, 1998;Mendlowicz et al, 1999) and one as an exploratory study of non-linear dynamic measures of variability (Hauge et al, 2011).

“…Although several reports have cited success in utilizing BL exposure times exceeding 30 min 25) , shorter implementation times are desirable. In the present study, participants were instructed to receive BL exposure for 10 min on workday mornings using a BL device (Travelite; Northern Light Technologies, Montreal, Canada).…”

Methods:We conducted a randomized crossover study involving registered nurses at a teaching hospital working a two-shift system including the night shift. Participants were instructed to expose themselves to BL for 10 min on workday mornings. Results: A total of 61 participants were enrolled in the present study. Thirty-one participants received BL exposure in the first month, and the other 30 received it in the second month. Significant improvements were noted in the BL periods compared with the non-BL periods for self-assessed sleepiness at 10:00 on day-shift days evaluated using the Karolinska Sleepiness Scale, self-assessment of night sleep for day-shift days using the Visual Analogue Scale and for fatigue assessed using the Checklist Individual Strength Questionnaire. The estimated mean difference for each scale (95% confidence interval) was -0.55 (-0.91, -0.20), 0.37 (0.04, 0.70) and -2.13 (-3.78, -0.48), respectively. Mean response time evaluated using the psychomotor vigilance task test (PVT) showed significant improvement in the BL periods compared with the non-BL periods. No statistically significant differences were observed for sleepiness at 14:00, depression, number of PVT lapses or frequency of perceived adverse events and near misses. Conclusion: Our findings suggest that brief BL exposure on mornings preceding a day shift is effective in improving sleepiness and performance during day-shift work, subjective nighttime sleep on day-shift days, and perceived fatigue for the preceding two weeks in rapidly rotating shift nurses.

“…One such theory states that a disturbed internal clock is causally involved in the development of depression (Winkler et al (2005), for review, see Racagni et al (2007)), which is supported by altered plasma cortisol rhythms (Deuschle et al 1997) and sleep patterns observed in most depressed patients and the recent licensing of agomelatine, which re-synchronizes disrupted circadian rhythms (Yous et al (1992), for review, see de Bodinat et al (2010)). In line with this, it was recently shown in rodents that chronic unpredictable stress affects suprachiasmatic nucleus (SCN) functionality, the central pacemaker of the circadian system in mammals, by dampening the amplitude of circadian PERIOD2 (PER2) protein expression, one of the main clock proteins involved in internal rhythm generation (Jiang et al 2011).…”

Recent findings in rats indicated that the physiological consequences of repeated restraint stress are dependent on the time of day of stressor exposure. To investigate whether this is also true for clinically more relevant psychosocial stressors and whether repeated stressor exposure during the light phase or dark phase is more detrimental for an organism, we exposed male C57BL/6 mice to social defeat (SD) across 19 days either in the light phase between Zeitgeber time (ZT)1 and ZT3 (SDL mice) or in the dark phase between ZT13 and ZT15 (SDD mice). While SDL mice showed a prolonged increase in adrenal weight and an attenuated adrenal responsiveness to ACTH in vitro after stressor termination, SDD mice showed reduced dark phase home-cage activity on observation days 7, 14, and 20, flattening of the diurnal corticosterone rhythm, lack of social preference, and higher in vitro IFNg secretion from mesenteric lymph node cells on day 20/21. Furthermore, the colitis-aggravating effect of SD was more pronounced in SDD than SDL mice following dextran sulfate sodium treatment. In conclusion, the present findings demonstrate that repeated SD effects on behavior, physiology, and immunology strongly depend on the time of day of stressor exposure. Whereas physiological parameters were more affected by SD during the light/inactive phase of mice, behavioral and immunological parameters were more affected by SD during the dark phase. Our results imply that repeated daily SD exposure has a more negative outcome when applied during the dark/active phase. By contrast, the minor physiological changes seen in SDL mice might represent beneficial adaptations preventing the formation of those maladaptive consequences.
