Air conditioning is open and closed, do you like which one when you are asleep?

In my country people don't use air conditioners, because it's quite moderate climate here, in the winter we even need to heat our houses, so I don't use AC too. Still, I like to sleep in a cool room, so I usually leave my window half opened. I do it in summer, because in some other time of the year it would get too cold inside my bedroom. It's also quite nice to fall asleep while listening to grasshoppers. They start to make their noise somewhere in the late summer. It's an excellent lullaby for me!:)

I have centeral heating and air, so I can control what it does by the thermostat. I don't concern myself with it. If it is that hot that it warnts use of the unit, I simply set it to where it'll turn itself on and off every so often. While you may think the body doesn't adapt to the cold air, that simply isn't true. The human body has its limits yes, but it can adapt accordingly as to what is, and isn't needed. For me, if its colder, in some cases (Most actually) it's actually better. Because my body can't handle the heat. I reach a cirtain point and everything closes up. So as long as the temperure is maintained at a cirtain level I'm fine.

Hello, I live in a place that require Heat and AC. I dont like both of them but sometimes I need them just to keep me cold or warm. But when I go to bed, then it has to be close. I rather open the window or cover with blanket instead. you are right, those are bad for you.

Hi, chocalate2010. If I have to run the air conditioner right on me when I go to sleep, I will try to have the air vents slightly pushed in. I don't want to wake up with a bad cold because of this. If I am not sleeping under the air vents, I will just, leave the vents opened.

Yes, you are right! It is not healthy no matter if it blows hot or cold air stream it is not good, because you breath it and it injures your lunges!

i agree that air conditioner keeps the room so cool,but it an artificial thing,it causes many problems to the nature. but our human body has already latent heat which causes to health. i switch on the air conditioner when i was using my computer,but when i sleep i switched it off,because already it is winter season.
