This study investigated the association between diurnal salivary cortisol profile and perceived stress at work and at home. Healthy participants (N = 180, 52% women) collected saliva cortisol samples immediately after waking up, 15 min later, 30 min later, and at 9:00, 12:00, 15:00, 18:00 and 21:00. The area under the cortisol awakening curve with respect to ground (AUCgCAR) and increase (AUCiCAR), and diurnal slope between 9:00 and 21:00 were analyzed. Perceived stress at work and at home was measured with the Stress-Energy Questionnaire. Participants reporting stress at home had significantly lower AUCgCAR and a flatter diurnal slope. When performing separate analyses for men and women, this association was only significant among women. Perceived stress at work was not associated with any cortisol measure. This study highlights the importance of stress outside the workplace. The sex differences may indicate an increased vulnerability to non-work stress in women.
