How Heat Kills And What It Does To The Body
Heat can kill by three main routes: heatstroke with organ failure from rising core temperature, heart strain as blood rushes to the skin and blood pressure falls, and dangerous dehydration stressing kidneys and causing shock. The brain also suffers, with confusion as a key early sign, especially in the elderly. Wet bulb readings show danger rising earlier than once thought, with humidity worsening outcomes. Medical teams cool victims quickly via cold water immersion or IV cooling, ice packs, and cooling mats, but in many cases outcomes remain grim.
