According to recent studies, employees' sleep at night is increasingly jeopardised. Employees are also often forced to sleep differently than would correspond to their preferred biological sleep rhythm. At the same time, other findings emphasise the relevance of good quality and sufficiently long sleep for mental well-being and physical health.

Therefore, our research project is dedicated to the effect of nocturnal sleep on the mental well-being and occupational performance of working people.

The primary aim of this research project, funded by the DFG and FWF, is the comprehensive investigation of processes that explain the relationship between sleep and performance. At the centre of this project are changes in well-being over the course of the working day. Furthermore, influencing factors that favour or impair these regulatory processes - such as the personal sleep type (chronotype) or situational work demands - will be investigated. A total of three studies with more than 500 participants are being conducted as part of this project.

The scientific results of our research project are also of great practical relevance. By demonstrating and explaining the links between sleep characteristics and well-being and performance at work, we are drawing attention to the day-specific mechanisms of action of sleep and their boundary conditions, which should be specifically taken into account in the promotion of health and performance in the workplace.
