Pollen-related allergic rhinitis (hay fever) is one of the most common allergic diseases in children and adolescents (Schmitz et al. 2017). In Germany, the 12-month prevalence of medically diagnosed hay fever among 3 to 17 year olds is 9.9% (Poethko-Müller et al. 2018). This results in an allergic reaction of the nasal mucosa and the conjunctiva to certain pollen, for example that of birch, which leads, among other things, to increased secretion, sneezing, restrictions in nasal breathing and itching. Although the symptoms of a pollen allergy can be very stressful and severely limit the quality of life and academic success, they are often trivialized (Greiner et al. 2011). In addition, high direct and indirect economic costs are attributed to allergic rhinitis and its secondary diseases, for example bronchial asthma and later COPD (Pfaar et al. 2014).
