According to the health authority, this situation will cause concentrations of inhalable particles of natural origin in the air to increase, affecting the regions of the Alentejo, Algarve and the interior of the Central Region.

This pollutant (inhalable particles) has effects on human health, especially on the most sensitive populations, such as children and the elderly, whose health care must be increased.

While this phenomenon continues, the DGS recommends that the population avoid prolonged exertion, limit physical activity outdoors and avoid exposure to risk factors, such as tobacco smoke and contact with irritating products.

Due to their greater vulnerability, children and the elderly, as well as people with chronic respiratory problems and cardiovascular patients, in addition to complying with general recommendations, should, whenever possible, remain inside buildings, preferably with the windows closed.

In case of worsening symptoms, DGS advises contacting Linha Saúde 24 (808 24 24 24) or, if necessary, using health services.
