Non‐pharmacological interventions for pollen‐induced allergic symptoms: Systematic literature review

Allergic diseases pose a health problem worldwide. Pollen are widespread aeroallergens which can cause symptoms like shortness of breath, cough, itchy eyes, or rhinitis. Apart from preventive measures and pharmacological treatment, also non‐pharmacological interventions have been suggested to reduce symptoms. The objective of this work was to review studies investigating the effectiveness of non‐pharmacologic interventions to reduce allergic symptoms.
