Weather, Pollution, and Heart Health: A City's Story

In Mashhad, a city nestled in northeastern Iran, researchers wanted to know how air pollution and weather affect heart health. They looked at data from 2017 to 2020, including weather details like temperature, humidity, and air pressure, along with pollution levels such as PM2. 5, PM10, NO2, SO2, and CO. Using a method called Random Forest, they found some interesting things. Time, air pressure, and temperature had a big impact on heart-related deaths. Among the pollutants, NO2 and SO2 were the most influential. Surprisingly, weather factors played a bigger role than pollution in heart health. The study also found that heart-related deaths increased with time, higher air pressure, colder seasons, and higher temperatures. All the pollutants, except SO2, also affected mortality rates. This study shows that understanding the link between heart diseases, weather, and pollution is crucial. With climate change and pollution on the rise, it's important for people, especially those with heart issues, to stay alert about weather changes.
