Air conditioning & heat are charming inventions.
Without them, every one of us would be uncomfortable at best & every one of us could potentially have life threatening conditions at worst.
I am absolutely grateful for our central air conditioner in the hot & humid summers. I am also grateful for our central heat in the cold winters. On a weekly basis when you go to work in the summer time or in the winter, opportunities are you work indoors. The majority of people who have office jobs or corporate jobs work inside. I am a professor & I spend alot of time inside our classroom with our students, then for our job, it is essential that I have both heating & cooling to keep our students safe & comfortable. Even though most of us spend the majority of our days inside in the heat or air conditioner, it is essential that every one of us get fresh air. This does not take away from how amazing & necessary heat & air conditioner are. Occasionally when you are indoors in an environment with heat or air conditioner, you may be exposed to dust. This is due to a/c filters not being cleaned as often as they should. It is pressing to inhale fresh, clean air outside. Fresh air is not always perfect, especially if someone is smoking near you or you live in an section with heavy polution, however, most times fresh air is healthier to breathe in than indoor air, and air conditioning, heating, & fresh air are all pressing for weird reasons & at weird times in our lives.
