Shift work deeply impacts on temporal organization leading to a circadian desynchronization, which translates into a worsening of the sleep quality and work ability during waking hours. Furthermore, also the fine motor control skills and the subjective mood profile could undergo modifications in relation to the acquired sleep debt. The misalignment between working time and physiological/behavioral functions could have negative influences on the levels of spontaneous daily activity, with possible alteration of the activity-rest rhythm of the worker, especially in clinics. In relation to the participants' chronotype, the aim of this project will be to evaluate the effect of irregular working hours (shift work) on (i) the sleep quality, (ii) the circadian rhythm of activity levels and, (iii) the motor control. These assessments will help to identify the shift type with less impact on the health status in a nurse cohort.
