advice about heat from Yale.
didn't know this.
"Be careful using fans in extremely hot weather: If the temperature is approaching
100 F, particularly if the air is dry,
running a fan can be more dangerous for your body."
They don't exactly explain in what way fans can be dangerous...

I think they're oversimplifying. If there is no air moving and the humidity is high, the air layer near your body will be hotter than ambient temperature. A little air movement will reduce your temperature. If it's very dry humidity, it will dehydrate you more than it cools you (since you're evaporating fast anyway) and could make you sicker.
