I go camping often throughout the year, and sometimes sleep in a tent in 85-100+F weather. If I put a box fan at the foot of the bed, blowing straight over me, it will cool me down to the point where I wake up and pull a blanket over me. (I always start with a sheet because cool air blowing directly onto on the bottom of my feet is uncomfortable.) Don't underestimate the power of the simple box fan.
