I sweat profusely at the slightest hint of physical exertion (thanks asthma) but I solved this with a box fan and a handful of sweatbands

I like to put the fan at either the front or back of the play area, it keeps you cool and the breeze and noise help keep you oriented in the real space, i found it helps a lot to stop people from losing their place.

sweatbands you can get at a sporting goods store for $6 to $12, depending on how nice you want them. I recommend cotton or nylon, polyester fabric is suffering.
