Working on-call with a night call resulted in a depressed (lower) cortisol awakening response (CAR) peak and post-awakening cortisol area under the curve with respect to ground (AUCG) the following day compared to when off-call. This may be due to exposure to noise, physical exertion, and stressful events during night callouts. There was no anticipatory effect to working on-call in any of the cortisol measures examined. This study, of male fire and emergency service workers who operate on-call from home, had two aims: (1) examine CAR and diurnal cortisol profile following a night on-call with a call, on-call without a call, and off-call; and, (2) explore whether there is an anticipatory effect of working on-call from home on diurnal cortisol profiles. Participants wore activity monitors, completed sleep and work diaries and collected seven saliva samples a day (0 min, 30 min, 60 min, 3 h, 6 h, 9 h, and 12 h after final awakening) for one week. CAR peak, reactivity and area under the curve with respect to increase (AUCI), post-awakening cortisol AUCG, diurnal cortisol slope and AUCG, and mean 12-h cortisol concentrations were calculated. The final analysis included 26 participants for Aim 1 (22 off-call nights, 68 nights on-call without a call, and 20 nights on-call with a call) and 14 participants for Aim 2 (25 days leading up to a night off-call and 92 days leading up to a night on-call). Generalized estimating equations models were constructed for each variable of interest. Aim 1: CAR peak and post-awakening cortisol AUCG\ were 8.2 {\textpm} 3.4 nmol/L and 5.7 {\textpm} 2.4 units lower, respectively, following a night on-call with a call compared to an off-call night. Aim 2: the day before a night on-call was not a significant predictor in any model. The lower CAR peak and post-awakening cortisol AUCG\ following a night on-call with a call compared to following an off-call night may be due to exposure to noise, physical exertion, and stressful events during night callouts. The lack of difference between the day before a night on-call and the day before an off-call night suggests there may not be an anticipatory effect on cortisol when on-call from home.

Some aspects of sleep quantity and quality may be affected when on-call. The two main stress systems are largely unaffected by on-call work, with the exception of the cortisol awakening response. Two characteristics of the cortisol awakening response were blunted when on-call with a night callout compared to when off-call.

On-call is an irregular work schedule allowing provision of 24-h services. Although it is purported that working on-call from home is stressful, little is known about impacts on stress physiology. This study aimed to (1) examine cortisol awakening response (CAR) and diurnal cortisol profile in fire and emergency service workers following a night on-call with a call (NIGHT), a night on-call without a call (NO) and an off-call night (OFF) and (2) explore whether there is an anticipatory effect of working on-call from home (ON) compared to off-call (OFF) on diurnal cortisol profiles.
