The best heat remedy used to be the dash fans. They were removed in our center about 10 years ago, the cited reason being maintenance cost, non uniformity in the district as well as a possible fire hazard due to being an add on and not being stock equipment. Instead now we have added on cameras, monitors, and telematics. All add-ons, and I'm no less overheated from pcm's encouraging me to drink more water and alternate with a corn syrup based sport drink with enough sodium to leach the calcium out of my bones. Hydration is necessary, but so is evaporation, and nothing drives that point home in this heat like a good breeze on your sweaty shirt. Something is lost when a latte sipping manager with his butt cemented to his desk chair, sitting under an a/c makes the decision to remove equipment that actually boosted production. Those who have never had a dash fan, will never know how much easier the job was when we had them.
