<human>:  How can I cool down a room without air conditioning?
<bot>: One option is to open the windows to allow fresh air in and create a cross-breeze. Alternatively, you could use a fan to circulate cooler air into the room. You could also dampen towels and hang them in front of the windows to keep cool air in. You could also get a window-mounted evaporative cooler, as these can cool a room down without the use of electricity.
