I'd never say no to some ultra calorie dense ice cream... fattening AND cooling, it's very practical for butterballs!!
To give a more serious answer, controlling airflow is REALLY important! Growing up my bedrooms were always over insulated and under ventilated so it'd get like a kajillion degrees in there; You wanna block out the sun with some blackout curtains or shades, then get a crossbreeze going! Windows on opposite walls or sides open if you can, let that air circulate and move over all that dough a bit more! Creating airflow routes for hot air to travel up and out, like through an attic or loft, are also good! And lastly: You could try putting a moist cloth over any fans or windows you might have, that way as the air flows the water evaporates and gets picked up!
