To help reduce flushing in hot weather I use a battery-operated person fan that I always carry in my purse.  The model I prefer has an adjustable head and a suction cup on the bottom.  The blade is soft plastic and is removable.  It operates on one C battery, which often lasts for several hours.  I buy them online, keep a few in reserves and stash one in the car and at friends’ houses.
