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.
