Given these forecasts, "a situation of poor air quality is expected on the continent, with an increase in the concentrations of inhalable particles of natural origin in the air," the agency said.

According to the Department, "this pollutant (inhalable particles – PM10) has effects on human health, especially on the most vulnerable population, children and the elderly, whose health care should be redoubled during these situations."

Therefore, and while this phenomenon continues, the DGS recommends that the general population avoid prolonged exertion, limit outdoor physical activity, and limit exposure to risk factors such as tobacco smoke and contact with irritants.

The most vulnerable groups of citizens, and the general population, whenever possible, should "remain indoors and, preferably, with windows closed," especially children, the elderly, and patients with chronic respiratory problems, notably asthma and cardiovascular disease.

Chronic patients should continue their medical treatments, says the DGS, emphasizing that if symptoms worsen, they should contact the Health 24 Line (808 24 24 24) or seek medical help.
