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, according to new research.

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, a team of researchers interviewed over 1,700 people from the Augsburg area of Germany about their allergies.

They differentiated between perennial or non-seasonal allergies — such as 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. “There are studies that focus on the psychological components of skin diseases or allergic asthma. For the first time, we are now able to show a connection with seasonal allergies,” explains Katharina Harter, the publication’s lead author. Around a quarter of those surveyed (27.4%) stated that they suffered from allergies, with 7.7 percent reporting perennial, 6.1 percent seasonal, and 13.6 percent other forms of allergic reactions.
