  Extreme Heat
  Heat kills by pushing the human body beyond its limits. In extreme heat and high humidity,
evaporation is slowed and the body must work extra hard to maintain a normal temperature.
Most heat disorders occur because the victim has been overexposed to heat or has over-exercised
for his or her age and physical condition. Older adults, young children, and those who are sick or
overweight are more likely to succumb to extreme heat.

Conditions that can induce heat-related illnesses include stagnant atmospheric conditions and poor
air quality. Consequently, people living in urban areas may be at greater risk from the effects of a
prolonged heat wave than those living in rural areas. Also, asphalt and concrete store heat longer
and gradually release heat at night, which can produce higher nighttime temperatures known as the
“urban heat island effect.”
