DONNA KELLEY, CNN ANCHOR: If you were with us just a few minutes ago, you know we were in an emotional news conference over the death of Minnesota Viking Korey Stringer -- 27 years old, passed away this morning from heat exhaustion. And our medical correspondent, Dr. Sanjay Gupta, is joining us. We will talk a little bit more about what heat exhaustion is and how you could avoid it.</s>DR. SANJAY GUPTA, CNN MEDICAL CORRESPONDENT: Right.</s>KELLEY: Hey, Sanjay.</s>GUPTA: Hi.</s>KELLEY: What's the difference between heat exhaustion and heat stroke? We talked about that a little bit before. Maybe you can refresh in case folks are joining us just now.</s>GUPTA: Sure. Heat exhaustion is actually at one end of the extreme. And heat stroke is what people think of when you start thinking of people having death, unconsciousness, all sorts of things. Heat stroke is the worst one. Heat exhaustion is often characterized by profuse sweating. Heat stroke is characterized by no sweating. And that's because your body's cooling mechanism has shut down. Your body's temperatures rise through the roof, greater than 103 degrees -- 108 degrees in the case of Mr. Stringer. Your organs start to shut down. Your brain may start to shut down. And you could subsequently die.</s>KELLEY: We're a little short on time, but let's try and tell folks what they should watch for and what they should do.</s>GUPTA: Certainly -- mentioning earlier, it's very hot outside. And when it gets very humid, you may not sweat quite as effectively as you would otherwise. Drink plenty of fluids before activities. Make sure to pace yourself. Very importantly, as well, is, when you get heat stroke, early stages of it, you may become sort of confused and you may forget to stop doing your activity; you may forget to start drinking. And all those sorts of things you want to keep doing.</s>KELLEY: OK. Dr. Sanjay Gupta, thanks very much.
