Dijk et al. (2012) [35] | Simulating night shift | Individual differences in amplitude of the melatonin rhythm were correlated with body temperature and cortisol. |
| Korompeli et al. (2009) [36] | Rotating and day shift work | The mean reduction of cortisol level between the two measurements was greater for the rotating than morning shift group. |
| Scheer et al. (2009) [37] | Simulating night shift | Daily cortisol rhythm was reversed. Subjects exhibit high levels of postprandial glucose responses. |
| Harris et al. (2010) [38] | Rotating shift (12-h day shift and 12-h night). Two weeks working followed by 4 weeks off work | Cortisol rhythm went back towards a normal rhythm in the second week, but it was not returned completely to normal levels when the workers returned home for the 4 weeks off period. |

Griefahn and Robens (2010) [39] | Simulating night shift | The increased of the CAR might be the anticipation of the upcoming demands. |

Ulha et al. (2011) [40] | Irregular shift and day shift workers | The concentration of cortisol declines throughout the day, reaching its lowest level during the night for day shift workers. Levels of CAR were higher on work days compared to days-off, for day shift workers. CAR levels were similar between work days and days-off for irregular shift workers. |
| Machi et al. (2012) [41] | Night and day shift workers | Morning cortisol peak was decreased or delayed after a night shift. |
| Wong et al. (2012) [42] | Rotating shift workers and day shift workers | High job strain elevated daily cortisol levels. |
| Nakajima et al. (2012) [43] | 24-h work shift and over the subsequent day-off | Early morning cortisol levels were attenuated after work. |
| Diez et al. (2011) [44] | Morning and afternoon shifts | Flattening of cortisol morning-evening difference. |
| Williams et al. (2005) [45] | Rotating shift (early morning-shift, dayshift, and control days). | Cortisol levels on waking were lower in the early morning-shift. |
| Kudielka et al. (2007) [46] | Day x night shift workers | Cortisol levels in permanent night workers seemed to be blunted during night work and days-off. Circadian cortisol levels were not disturbed in former night workers who recently switched to fast rotating shift schedule. |
| Boquet et al. (2004) [47] | Rotating shift work: clockwise x counterclockwise direction. | No significant differences of rotating shift condition for cortisol or melatonin. |
| Vangelova (2008) [48] | Rotating shift | Higher salivary cortisol during morning and night shifts in the backward rotating group. |
|
de Valck et al. (2007) [49] | Rotating shift: fast-forward versus a slow-backward rotating shift | Salivary cortisol did not significantly differ between the fast-forward and the slow-backward rotation shift systems. |
| Looser et al. (2010) [50] | Day shift | Associations between cortisol levels and heart rates, during periods of high stress. |
| van de Werken et al. (2014) [51] | Simulating Shift work | Exposure to stress, as in shift work, is predicted to result in abnormal cortisol levels. |
