Avoid Traffic-Related Air Pollution: Close Your Windows in Peak Hours
While I 100% stand by this, I do want to put a caveat on it.
If you live near a busy road OR you live close to a school OR you get heavy traffic around your home at certain times, then please don’t open your windows.
I know that sounds obvious… but sometimes the obvious needs to be stated.
There are many noxious gases in exhaust fumes, including the deadly carbon monoxide.
So, if there is a busy time for traffic near your home, be sure to close the windows to keep these fumes out.
