Sahara dust reaches Switzerland: What this means for our health
In recent years, experts have observed a phenomenon that is affecting Switzerland more and more frequently: Sahara dust, carried by strong storms in the desert, is reaching our region. These fine sand particles are transported northward across the Mediterranean by air currents and settle over the Swiss sky like a veil.
For the population, this weather phenomenon has noticeable effects. When the dust reaches Switzerland, the sky often turns yellowish or orange. However, the high concentration of particulate matter in the air we breathe is particularly problematic. The tiny particles can penetrate deep into the respiratory tract and cause irritation there.
For people with pre-existing respiratory conditions, such as asthma or chronic bronchitis, the Sahara dust poses a particular health burden. Doctors therefore advise those affected to avoid strenuous physical activities outdoors on days with high dust levels and to keep windows closed as much as possible to keep indoor exposure low.
Scientists assume that the intensity of these dust events could increase in the future due to climate change and changing weather conditions. While the natural spectacle often provides fascinating images for photographers, health precautions remain an important issue for the Swiss population. Authorities regularly provide information on current air quality when levels are particularly high.
