Our expert, Prof. Dr Timo Kortsch, explains the term “digital stressors” for us. The professor of business psychology also outlines the psychological factors and technological mechanisms underlying these stressors.
Digital stressors are stress factors that arise from digital technology and digital communication and trigger or exacerbate digital stress. These include, above all, information overload and constant availability (too many emails, chats and feeds), frequent notifications and interruptions, pressure to respond quickly and time constraints, multitasking, and complex or frequently changing tools.
If there are no clear boundaries between work and private life, or if social comparison and FOMO (Fear of Missing Out) come into play, the digital burden increases further.
There are fundamental psychological reasons behind our reliance on smartphones and other devices. For instance, we react strongly to new information and small rewards, seek a sense of belonging, and tend to manage our emotions through distraction. At the same time, we’re driven by the fear of missing out.
Typical psychological factors:
These psychological factors would be less effective if digital tools did not specifically reinforce them.
Mechanisms: how digital tools work
Digital tools reinforce the psychological factors by being constantly available, deliberately capturing users’ attention and providing feedback in variable, hard-to-predict patterns.
Typical technological mechanisms:
These factors and mechanisms apply to all digital devices, although they are most prevalent in terms of smartphones. From a psychological perspective, smartphones are highly optimised behaviour reinforcers.

One cause of digital burnout lies in “constant mental stimulation in everyday life”, explains Prof. Dr Stefanie André, Professor of Health Management at IU International University of Applied Sciences. It is important to note that: it is not digital availability itself that is the source of stress, but rather the expectations, feelings and fears associated with it. The findings of the representative IU study confirm this too.
42.2% of employees, apprentices and trainees in Germany are familiar with the feeling of having to be constantly available, both at work and in their private lives. Almost a third even feel obliged to be available outside working hours.
Question: To what extent do you agree with the following statements?

Additional findings on stress factors in the workplace can be found in our IU study on leisure sickness.
More than half of respondents feel that those around them expect a prompt reply to digital messages. And more than a fifth say that: in my circle, it is not acceptable for me not to reply to messages straight away.
Question: To what extent do you agree with the following statement? “I feel that the people around me expect me to reply to digital messages immediately.”
