Officials cited extreme heat as the cause of death in more than 40 cases nationwide over the week of the Fourth of July - at least three of those deaths happened in Central Indiana. One of the deceased, a 92-year-old man, was found dead in his unventilated home, according to a news release from the Marion County Public Health Department. Another victim, a 54-year-old man, was found dead outside his house. In addition, two babies were found left in parked cars over the weekend - one died. Aside from the basics of hot-weather survival (don't leave ANYTHING in the car; drink lots of water; find AC; check on people who may need help), officials offered a reminder that fans are not adequate to the task of cooling one's body in high heat and, in fact, can be counterproductive by raising body temperature when they are simply recirculating hot air.
