Research links air pollution to childhood learning and sleep issues

Recent international studies have identified air pollution as a significant factor contributing to learning difficulties and sleep disturbances in children. Research from the University of Cambridge indicates that even in cities with relatively low pollution levels, fine particulate matter (PM2.5) is directly linked to nighttime coughing and fragmented, shallow sleep.

Furthermore, a large-scale study by the Oregon Health & Science University involving over 12,000 children found that exposure to air pollution accelerates cortical thinning in the brain. This physiological change affects areas responsible for emotional regulation, learning abilities, and decision-making. Experts suggest that the combination of poor sleep quality and chronic inflammation caused by microscopic particles can lead to long-term declines in school performance and increased anxiety.

In Hungary, data from the Hungarian Central Statistical Office shows an 8% increase in children registered with severe attention deficits over a single year, rising from 7,875 to 8,506. However, experts like Dr. Krisztina Bohács note that this rise may be attributed to improved diagnostic recognition, changing regulations, and reduced social stigma rather than a true increase in ADHD prevalence.
