Learn how extreme heat affects the body

  • Sweating causes loss of water and blood salt from the body (dehydration)
  • Not enough water to sweat for cooling, body gets even hotter.
  • Also, blood is thicker, harder for the heart to pump
  • Heart tires, weakens, reduces circulation, oxygenation. Kidneys can’t clean the blood as well
  • Whole body exhaustion
  • Brain function reduces – fainting, cramps, dizziness, confusion, uncoordinated movement
  • Heart urgently works harder, burning more fuel, heating body more
  • Clammy skin
  • Death
