Rising temperatures bring risk for heat-related illnesses July 7, 2021 JACKSON, Tenn. — As temperatures and dew points begin to increase this summer, the risk for heat-related illnesses does as well. “During the summer time, the number rises, so you may see about 10 percent of the population may develop some type of heat illness,” said Mechelle Taylor Moragne, the owner and a physician at Taylor Medical Center. The two main heat-related illnesses include heat exhaustion and heat stroke, both of which can be deadly. “Heat stroke is really the most dangerous of that. The heat exhaustion is feeling the fatigue, just when your body overheats,” Moragne said.
