Recent health-related studies in Germany have examined various aspects of public well-being, including the physical effects of time off and the impact of living environments. A study by the International University of Bad Honnef-Bonn found that 22 percent of Germans experience ‘leisure sickness,’ a phenomenon where individuals suffer from symptoms such as fever, fatigue, and nausea during holidays. Researchers suggest this may be linked to psychological factors or the suppression of the immune system due to chronic stress. In contrast, a survey by DAK-Gesundheit reported that 86 percent of vacationers rate the recovery effect of summer holidays as good or very good, noting that high temperatures did not significantly disturb their relaxation. Additionally, research by the Forsa-Institut regarding living environments in Berlin and Brandenburg found that while 61 percent of residents view their surroundings as ‘rather healthy,’ concerns remain regarding air quality, safety, and noise levels. ## Timeline ### 2026-09-20: Lake Como faces landscape concerns amid luxury tourism surge Italia Nostra warns that rapid luxury tourism development in Lake Como is threatening the region's historical and natural landscape, despite attracting 30% of Italy's hotel investments. 9 sources. https://clstr.news/cluster/german-health-surveys-examine-vacation-trends-and-living-environments ### 2026-08-28: Leisure sickness affects 22 percent of Germans during holidays A study shows 22 percent of Germans suffer from ‘leisure sickness,’ experiencing symptoms like fever and fatigue once work stress subsides during vacations. 3 sources. https://clstr.news/cluster/leisure-sickness-affects-22-percent-of-germans-during-holidays --- Cite as: German public health and well-being trends.
