There are ceiling fans in every room of the house.
I love to have the one in my bedroom going all the time when home.
Even though I can't sleep without my soft blanket, even in the summer, the ceiling fan makes the room temp just right and I like the soft whir.
Only problem is like
@Chance mentioned, if you have eye problems the doctors will tell you NO.
I have allergies and dry eyes. Sometimes I will relax with a cool sleep mask if I lay down in the day, but at night the doctor prescribed a steroid gel for the lining of my lower lid that keeps my eyes moist all night and helps with inflammation.
Also you can use the ceiling fan as an air cleaner.
Go to a hardware store and ask for ceiling fan filters.
You past one on each blade and as it turns they take dust out of the air. Change them often like any other air filter.
I got new glasses today and there was a script change.
Having a hard time adjusting to them. I think I would rather see through my old script. At least they are comfortable. More like natural eyesight. Progressive lens are hard to get used to also. But, I'll try them for a few days and see if my brain adjusts.
