Seasonal allergies to different types of grass or tree pollen are more common in people with anxiety disorders, while patients with depression are more likely to suffer from perennial allergies triggered by allergens such as animal hair. These are the findings of a team of researchers from the Technical University of Munich (TUM). Conversely, food and drug allergies were unaffected by these psychosocial disorders.
The team interviewed over 1,700 people from the Augsburg area of Germany about their allergies. Led by Claudia Traidl-Hoffmann, Director of the University Center for Health Sciences at University Hospital Augsburg (UNIKA-T) and Professor of Environmental Medicine at TUM, the team differentiated between perennial or non-seasonal allergies for example those triggered by house dust mites or animal hair, seasonal allergies caused by grass pollen for instance, and allergies to other substances such as food.
The study participants also answered questions about their psychological health. The focus here was on depression, generalized anxiety disorders – which affect all aspects of daily life and acute mental stress.
