Heat stroke isn't a stroke but it can kill you just as fast

Dr. McGeorge addresses common concerns about extreme heat, emphasizing that heat stroke is a life-threatening emergency caused by dangerously high body temperature, which can result in brain and organ damage or death if not treated quickly. He explains that symptoms usually begin with heat exhaustion -- such as fatigue, headache, and nausea -- before progressing, and highlights the particular risk for elderly individuals who may not recognize the danger. For prevention, Dr. McGeorge advises staying hydrated, monitoring urine color, and checking on vulnerable populations during heat advisories.
