Freezer ziplock bag full of ice to go around your neck will cool your core down quick. You can also just regularly goto the faucet and rinse your wrists and neck with cold water to help cool your body down as well. I live on the river, so I keep the windows open for the breeze and the blinds down to block sunlight. I've heard of constructing a water tank that fits to your windows, and what happens is the sun heats the water up over the course of the day, but still lets water in, and then at night when its cool outside, the windows maintain an even temperature releasing heat. I know some people do this in their kitchen windows using clear glass bottles filled with water stacked on top of eachother to fill the window.
