Even if you pay a brief visit to a polluted city can affect your health, says a study.
Done by researchers at UCLA, the study shows that even a short-term visit to a highly polluted city can be detrimental to one’s health.
The study involved 26 non-smoking, healthy adults (with a mean age of 23.8 years) who traveled from Los Angeles to Beijing during the summers of 2014 and 2015 over a 10-week period.
The study participants were split into two groups and blood samples were taken in the first group at eight weeks and in the second group at six weeks after arrival in Beijing. The study was done in collaboration with Peking University in Beijing.
The participants experienced significant health changes during their time in Beijing, including higher levels of oxidized fats, causing increased heart inflammation; and a change in enzyme function, which is associated with heart disease. The study also found that these individuals had up to an 800% greater concentration of air pollutants in their bodies than they did when in Los Angeles.
