Sahara dust reaches Switzerland: What this means for our health
In recent days, fine desert dust from the Sahara has increasingly reached Switzerland. This weather phenomenon occurs when strong storms in North Africa swirl sand particles into the upper layers of the atmosphere and transport them with the wind across the Mediterranean to Europe.
For the population in Switzerland, this event is clearly visible. The sky often turns yellowish or orange, and a fine layer of reddish dust settles on cars and windowpanes. Experts observe that such weather conditions are becoming more frequent due to climate change and more intense storms in the Sahara.
However, Saharan dust does not only have visual effects; it also influences air quality. The fine particles can enter the respiratory tract and lead to health problems for sensitive individuals. People with asthma or other respiratory diseases, in particular, should be cautious when dust levels are high.
Medical professionals recommend reducing physical exertion outdoors when dust levels are high. Keeping windows closed can also help to keep indoor exposure low. Although the dust usually clears after a few days, the question remains as to how the increasing frequency of such events will affect the health of the Swiss population in the long term.
