The interplay of sleep, personality and affective shift

Current polls show that the sleep of employees is increasingly at risk and is not always aligned with the personal, biologically preferred sleep window. At the same time, other findings illustrate the relevance of sleep of good quality and sufficient duration for well-being and physical health. Our project contributes to current research by investigating the relevance of sleep for employees well-being and performance at work in greater detail. The primary goal of our research project is to investigate explanatory mechanisms between sleep and performance. The focus of interest is on changes in well-being over the course of a work day. Furthermore, factors that potentially alter these processes such as sleep type (chronotype) and daily work demands will be investigated. In sum, three studies with a total of more than 500 participants will be conducted. The scientific results of our research project are also of high practical relevance. By demonstrating connections between sleep characteristics and well-being and performance at work, we are drawing attention to the day-specific mechanisms of sleep and their boundary conditions, which should be considered to promote health and performance at work.

Recent polls show that the sleep of employees is increasingly at risk and is not always aligned with the personal, biologically preferred sleep window. At the same time, other findings illustrate the relevance of sleep of good quality and sufficient duration for well-being and physical health. Our project contributed to current research by investigating the relevance of sleep for employees' well-being and performance at work in greater detail. The primary goal of our research project was to investigate explanatory mechanisms between sleep and performance. The focus of interest was on changes in well-being over the course of a workday. Furthermore, factors that potentially alter these processes - such as sleep type (chronotype) and daily work demands - were investigated. In sum, three studies with a total of more than 400 participants were conducted. The results of our studies show that good and sufficient sleep supports self-regulatory processes the following day. For example, efficient and sufficient sleep enabled a mindful start into the working day. As a result, employees experienced less procrastination. In one of the studies, we took advantage of the shift to daylight saving time to show quasi-experimentally that a reduced quality of sleep due to the shift to daylight saving time is reflected in diminished creative performance at work. Contrary to expectations, people's sleep type (chronotype) could not be identified as a relevant factor modulating these processes. The scientific results of our research project are also of high practical relevance. By demonstrating connections between sleep characteristics and well-being and performance at work, we are drawing attention to the day-specific mechanisms of sleep and their boundary conditions, which should be considered to promote health and performance at work.
