The air we breathe contains pollutants of natural origin (sea spray, dust, pollen...) or resulting from human activities (road traffic, energy production, industry, agriculture...). The penetration of these pollutants into the body can have short- and long-term health consequences, even at low concentrations. 

In the short term, exposure to pollutants can trigger irritating symptoms in the eyes, nose and throat, either immediately or over the following days. Exposure can also amplify respiratory illnesses such as asthma and bronchitis.¹

Exposure to air pollution over several years can have far greater health effects than short-term exposure. Numerous studies show the role of air pollution in reducing life expectancy and mortality, and more specifically in the development of cardiovascular disease, respiratory disease and lung cancer. Chronic exposure to air pollution particles, produced largely by motorized traffic, is one of the factors incriminated in the rising prevalence of respiratory allergic diseases. For example, chemical pollutants in the air can increase people's sensitivity, making them more susceptible to pollens. ²

However, measures are being taken to improve air quality: in 2021, the French government introduced a plan to halve atmospheric pollutants by 2030, in particular by changing domestic wood heating systems, the main source of fine particle emissions.³
