LAS VEGAS, NEV. (April 21, 2025) — Temperatures are rising and trees are in bloom, which can only mean one thing: the return of allergy season. Beginning this month, oak trees become a major source of allergenic pollen, followed by ash trees and pine trees in the next few months. Touro University Nevada College of Osteopathic Medicine Dean, Dr. Wolfgang Gilliar, who was born and raised in Germany, is sharing the self-care routine millions of Europeans use to keep allergy symptoms at bay.
The German self-care trick known as “lüften” has been a long tradition to aerate living spaces such as bedrooms, bathrooms and kitchens. Social influencers who swear by the method, such as Bridget, have also posted about the tradition. “Lüften” literally translates to “airing” or letting the air in and refresh the air inside of a closed space. It means to establish good, natural ventilation through opening windows (or doors) for a set amount of time to “refresh” the internal air space in our living quarters.
The proposed benefits are better hygiene, reduction in respiratory problems such as asthma and potentially bolstering the immune system. It can also help with allergies and alleviate those symptoms. Intermittent “lüften” has shown to be more effective as over-the-counter allergy relief medication as it provides relevant and effective air exchange rather than drying out the living spaces that happens with low-grade constant aeration.
