I entirely enjoy being awake at the crack of dawn here where I live, and this is because the air quality is perfect at this time of afternoon where I live, and as the afternoon goes on the air quality starts to deteriorate.
It is an entirely different thing, occasionally by the middle of the afternoon the air quality is so awful that you feel like death warmed over, and if you have allergies it could entirely cause some drastic health problems with breathing and such.
This is why I invested in a whole home air purification plan for my home. I am one of those people with awful allergies. Without this whole home air purification plan I am not sure I would survive the entire afternoon! The crack of dawn though the air quality is superb. Make sense out of that! This is how different this area I live in is. You can have the most healthy air quality in the absolutely early morning but by afternoon you would never suppose you were even in the same site. I do not know why this is and it did not consistently used to be this way. This has only started in the last 6 months or so. It is absolutely strange, however but I am thankful that I have a whole home air purification plan to get me through the rest of the afternoon and I am also glad that I work from home, so this way I can have great indoor air quality while it is horrible outside. If I had to go out to work, forget it! I would never be able to hold the job!
