Sahara dust reaches Switzerland: What this means for our health
In recent months, meteorologists have observed an intensifying phenomenon: fine desert dust from the Sahara is reaching Switzerland with increasing frequency. The cause is more intense storms in North Africa, which swirl sand into the upper layers of the atmosphere and transport it across the Mediterranean to our region via strong winds.
For the Swiss population, this event is not only visible through a yellowish sky or deposits on cars and terraces. The fine dust penetrates deep into the respiratory tract and can lead to health problems in sensitive individuals. People with pre-existing respiratory conditions or those with allergies, in particular, clearly feel the increased strain on air quality.
Experts advise reducing physical exertion outdoors when concentrations of Saharan dust are high. Those suffering from asthma or other respiratory problems should be cautious on these days and, if necessary, stay indoors. Closing windows can also help keep exposure to the fine particles inside the home to a minimum.
Although the phenomenon of Saharan dust is generally well-known in Switzerland, the increasing frequency and intensity are causing concern among researchers. It remains to be seen how future climatic changes will affect air quality in Switzerland. Authorities continue to monitor the situation closely in order to inform the public in a timely manner if necessary.
