It is a common way to cool a room in the summer by running a fan, but in fact the air gets heated by the way the fan operates. I am not saying don't run the fan; we are all used to it, but I am saying let nature do its thing for some part of the day.
The law of physics says that warm air is light and cold air is heavy, so a good natural solution is to keep the windows and doors of your house or room closed but keep the skylight open during the day. Due to this, the light, hot air will continue to go out from above, giving way to fresh air, and the cold, heavy air will remain below.
