A single new report, dated October 9, 2026, describes a study of ozone exposure in endurance athletes. According to this report, the study found that the inhaled pollutant dose rises as breathing increases during harder exercise. The report states that because ozone is invisible, athletes may not notice its effects on their lungs during workouts. The research focused on how higher exercise intensity raises the amount of air, and potentially more pollutant, moved through the lungs. No other reports, conflicting figures, or additional dates are included in the supplied coverage, so the chronology consists only of this one development.
