Air Pollution Linked to Mental Health Issues and Respiratory Symptoms

Research presented by Professor Yang Liu of Emory University highlights that air pollution, especially fine particulate matter (PM2.5) from sources such as forest‑fire smoke, can aggravate anxiety and depression and may accelerate neurodegenerative processes linked to Alzheimer’s disease. Liu explains that inhaled toxic smoke triggers systemic inflammation, which in turn affects brain function. Protective measures such as certified masks and validated air‑purifying devices are recommended, though their effectiveness varies.

Medical guidance in Poland notes that chronic exposure to polluted air often produces a characteristic “morning cough.” Health authorities advise seeking medical attention if the cough persists beyond three weeks, or if it is accompanied by shortness of breath, hemoptysis, severe chest pain, or fever above 38 °C. The World Health Organization estimates that air‑pollution‑related respiratory and cardiovascular diseases cause millions of premature deaths each year, underscoring the broader public‑health urgency.
