- 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.
