 That's Dee Jepson. She's a professor of safety and health, Ohio State University. And she says a lot of people get very sick from the heat and many lose their lives from it because the symptoms can sort of sneak up on you. And those symptoms may not be noticed at first by others around you. Also, she says the symptoms vary with each person. Heat illness is really hard to recognize and hard to predict because each one of our bodies, you know, are so different.
