Organisations' digitalisation has had positive and negative effects on the work environment. Regardless, the digital work environment can affect employees' digital well-being. By studying how lecturers at Swedish universities feel that their digital well-being is affected by the digital work environment, the universities can proactively work for a good work environment. This quantitative survey studies essential factors for the well-being of lecturers in the digital work environment at Swedish universities. The variation is explained using the Job Demands-Resources model (JD-R) and the Demand-Control-Support model.  The most important factors for digital well-being that have emerged in this study are to have a positive attitude towards digital systems, to have digital competence and to minimize negative impact; this is also confirmed by previous research in other environments.
