Prof. Dr André, why do many employees become ill when stress levels decrease?

Leisure sickness describes symptoms such as headaches, nausea or exhaustion that occur mainly during leisure time, when we should actually be relaxing. One possible reason lies in the autonomic nervous system: during periods of stress, the sympathetic nervous system dominates, while the parasympathetic nervous system is responsible for regeneration. In cases of chronic tension, it is difficult to switch between the two, and the body reacts to relief with exhaustion.

People with a high level of perfectionism or a need for control are particularly affected. Constant digital availability also prevents mental disengagement, as the brain remains in work mode and relaxation is inhibited.

Companies can provide targeted support by promoting a culture that allows and enables rest and relaxation. This includes training in relaxation techniques, leading by example, flexible working patterns and clear communication rules.

Digital tools such as AI-based self-checks or wearables such as the Oura Ring provide biofeedback on stress levels, sleep and relaxation. They help to identify overload at an early stage and to promote individual regeneration. Such technologies strengthen self-awareness, which is a key to mental health in an accelerated working world.

What do you think about the results of the study? Are you surprised that 71.9% of employees in Germany have experienced leisure sickness at some point?

No, I’m not really surprised. The results of the study are consistent with my observations and research on the subject. But that doesn’t make the figures any less alarming. Imagine the consequences leisure sickness can have in jobs where safety is important. If a doctor or pilot is not sufficiently rested, the risk of making mistakes increases significantly. Therefore, leisure sickness is a social issue, even if you are not personally affected by it.

Women are particularly susceptible. Many women have primary responsibility for care work in addition to their paid jobs and thus have little time for genuine rest and relaxation. Even free time is often filled with mental responsibilities, such as organising family life or providing emotional support. This sustained level of activity without breaks promotes precisely the physical and mental reaction known as leisure sickness. In emotionally demanding professions, chronic exhaustion can thus become a silent danger to health and the quality of work.

When does leisure sickness become an illness?

Leisure sickness is the body’s warning sign and should be taken seriously, even if it is not an official diagnosis. The symptoms are often non-specific and come and go, which means they are easily overlooked in everyday life. If ignored, there is a risk that the constant stress will develop into chronic fatigue syndrome or other health problems. Therefore, early attention and countermeasures are crucial.
