  • Exercise lowers the risk of heart disease, cancer, and early death.
  • A new study suggests polluted air may reduce the benefits of exercise.
  • Researchers analyzed health data from over 1.5 million adults across multiple countries.
  • Focus was on PM2.5 particles, which can cause inflammation and long-term damage.
  • Exercise reduced death risk by 30% in less polluted areas but only 12-15% in highly polluted areas.
  • In regions with PM2.5 above 35 μg/m³, exercise offered even less protection, especially against cancer deaths.
  • The study emphasizes that exercise remains beneficial but improving air quality enhances health gains.
  • Toxic air can partially block exercise benefits but doesn’t eliminate them.
  • Clean air and physical activity are both crucial for healthy aging.
  • The study acknowledges limitations, including data mostly from high-income countries and lack of indoor air quality data.
  • Recommendations include checking air quality and choosing cleaner routes for outdoor exercise.
  • The study highlights the serious global problem of air pollution and its impact on health.
  • The study was published in BMC Medicine.
