Climate change and asthma: work-related risks and planetary implications.

OBJECTIVE Asthma is a chronic respiratory condition characterized by airway inflammation and hyperresponsiveness to internal and external factors. In addition to well-known irritants such as allergens and pollutants, weather conditions-amplified by climate change-are increasingly recognized as contributors to asthma symptoms. METHOD This study gives an overview of the literature on Asthma and Climate Change, the Occupational Risks, and Planetary Health Implications. RESULTS Environmental changes in temperature extremes and allergen levels can disrupt immune regulation-specifically, the Th1/Th2 balance-thereby contributing to airway narrowing, and stronger inflammatory responses. Climate change worsens respiratory health by prolonging pollen seasons, intensifying allergies, fostering mold and pests, and triggering asthma through extreme weather. CONCLUSIONS Given the growing impact of climate change, increasing public and professional awareness is key to safeguarding vulnerable populations and promoting long-term respiratory health.
