Air pollution caused up to 8.9 million premature deaths with cardiovascular diseases as the primary cause. Although the air pollution level in the U.S. is at the lower end worldwide, millions of U.S residents travel to a country with severe air pollution every year, and it remains unclear whether a short-term visit to polluted areas causes any adverse health effects. To fill this knowledge gaps, we performed a natural experiment on a group of international travelers and biomonitored their exposures to air pollutants and the subsequent health effects.
