QUICK SUMMARY: New research from China finds that exclusive breastfeeding for 6 months (or longer) could help reduce the negative impact of air pollution. Researchers looked at links between maternal exposures to air pollution DURING PREGNANCY and the risk of allergic disease for pre-school children. With babies who were exclusively breastfed for 6 months or more, “the associations were significantly reduced.”

As you probably know, a child exposed to air pollution is at increased risk of developing allergic disease, for example, allergic rhinitis (AR).

Allergic rhinitis (AR) is a non-infectious chronic inflammatory disease — it is when your nose gets irritated by something you’re allergic to. For example, pollen — which causes sneezing, runny nose and other symptoms.

Over recent decades, allergic rhinitis has been on the rise, especially in high-income areas, like in cities. Among other factors, ambient particulate matter which are pollutants emitted from power plants, industries and exhausts of cars, have been linked to allergic disease.
