"Safe" air pollution is like invisible cookies that we eat every day, most of the time, they're harmless, but too many can make our hearts work harder.
Imagine your heart is a little engine, and it needs to keep running all day long. When you breathe in clean air, it's like giving your engine spark plugs, everything runs smoothly. But when there are some tiny invisible particles floating around in the air, like those from cars or factories, they're like little bits of dirt that get stuck in your lungs.
Your heart senses this and says, "Hmm, I need to work a little harder to help you breathe!" So it pumps faster. That's okay for a while, it's like when you run up the stairs and your heart beats quicker. But if this happens too much, especially over time, your heart can get tired.
This is what "safe" air pollution does, it doesn’t hurt us right away, but it adds extra work to our hearts every day, just like eating a few more cookies than usual, and eventually, the heart might say, "I need a break!""Safe" air pollution is like invisible cookies that we eat every day, most of the time, they're harmless, but too many can make our hearts work harder.
