The extreme heat poses severe health risks, including dehydration, heat exhaustion, and life-threatening heat stroke. Vulnerable groups, such as older adults, young children, and those without access to air conditioning, are at heightened risk. The lack of overnight cooling exacerbates these dangers, as the human body has fewer opportunities to recover. Outdoor workers and tourists visiting national parks in Utah and Nevada are also at risk. The NWS has emphasized that heat-related illnesses can escalate quickly, with symptoms such as dizziness, nausea, and confusion potentially leading to organ failure or death if untreated.
