Engagement in outdoor physical activity under ambient fine particulate matter pollution: A risk-benefit analysis.

ABSTRACT:

Background

Outdoor physical activity (PA) brings important health benefits, but exposure to polluted air increases health risks. This study aimed to quantify the tradeoff of PA under fine particulate matter (PM_2.5) air pollution by estimating the optimal PA duration under various pollution levels.

Methods

A risk-benefit analysis was performed to estimate the optimal outdoor moderate-intensity PA (MPA) duration under varying PM_2.5 concentrations.

Results

An inverse nonlinear relationship was identified between optimal MPA duration and background PM_2.5 concentration levels. When background PM_2.5 concentration increased to 186 µg/m³, the optimal outdoor MPA duration decreased to 2.5 h/week, the minimum level recommen
