How to make Room's celling COLD !!!

From what I know about our ceiling fan, there is a way to reverse it. I would look into getting blinds, or curtains. If you know the manufacturer of the fan, maybe you could go on the net and see if there is a switch to get it to throw cold air. I guess you do not have a portable air conditioner or a thermostat control in your place so that you could turn the temperature so the air conditioner starts to work.

Hmmm...How low is your ceiling? Coz what I know is that when your ceiling is very low then the house/room can be very hot. We once lived on a rented house that has a low ceiling and the house was indeed very hot! We weren't able to take anymore it so we moved to a house that has a ceiling high enough so that air can properly circulate inside the house. If your ceiling though is not low and your room still gets hot then maybe you can put some curtains in your terrace which you can pull down only when the sun is out and streaming directly unto your terrace. Or you can also put some indoor plants in your room. At least the heat coming in will be lessen. Hope it helps :)

This summer I made some paper fans and put them in glaring locations. It increased the darkness, but gave relief from heat. Who wanted glaring light anyway? But seems not a right solution for your problem..... why not wet your terrace regularly...? Maybe it will help in cloud formation.....

Get a fan and place it near your bed. Then take some clothes pins and pin your sheet around all edges of the fan. Make sure that the rest of the sheet is tucked in around the bed and under your head/pillow. Its like sleeping in an air conditioned bubble. Works great! Keep the door to your bedroom open, so that there is proper air circulation from other rooms. Keep in mind that this may not improve your condition if your house, apartment, etc. is the same temperature or hotter than your bedroom. Still another option is to get a large powerful fan, such as one at least 16" in diameter and put it facing outward in a window in another room than the one you are sleeping in. Then, close all other windows in the house except the one the fan is in, and where people are sleeping near. The fan will exhaust hot air out of the room and create a vacuum which will pull in the cooler night air from the outside through the open windows where people are sleeping. Prop the doors in the bedroom(s)somewhat next to yours open, to create a path for air to migrate. This is much more effective than having a loud fan blowing the same hot room-temperature air back at you. It also does not suck small bugs through the screen like having the fan pointed inward sometimes does. This, of course, assumes it is nighttime, and that it has become significantly cooler outside than during the day, when your room celling warmed up. If you have a lot of people sleeping or you want more airflow, get a more powerful fan, or put another exhaust fan facing another open window. You can use a air conditioner for your room.
