Is there any body cooling/fan hacks or gadgets you know?

2016, 1:30 am, its like 85 degrees in my hotel room.

is there any way to cool off or any small portable fan i can buy for travel that will cool me somewhat better than a tiny portable fan? or a lifehack? or a way to build a sweet ass cooling system for cheap?
