Heat Stroke - Weather Definition

By

Definition: Heat stroke is a serious heat-related illness that requires immediate medical attention. Death or serious disability can result if symptoms are not brought to the attention of a medical professional. After exposure to extreme heat for extended periods, the body loses its ability to cool down naturally through sweating and evaporative cooling. Think of a thermostat in your house...If it breaks, there is no way to control the temperature of a room.

  • Dizziness
  • Severe headache
  • Nausea
  • Hot, dry skin without sweat
  • High pulse rate
  • High body temperature
  • Unconsciousness
