Man’s brain “fried” in heat Arizona heat wave

After suffering massive burns during the Arizona heat wave, experts say a man’s brain was fried after his internal temperatures reached 107. He was reportedly slamming his head on a truck before passing out. This incident serves as a reminder to take necessary steps to avoid heat stroke. When it takes hold, “the brain's function becomes totally disarrayed and you have things like confusion, coma stupor, seizure activity, and even intracranial bleeding,” Ralph Riviello, professor and chair of the Department of Emergency Medicine at The University of Texas Health Science Center at San Antonio said in an article.
