🔍 Key Concepts

• Body cooling mechanisms: especially the role of sweating and evaporation in controlling body temperature • Typical signs and symptoms of heat cramps, heat exhaustion, and heat stroke • Which heat illness is considered a medical emergency due to failure of the body’s temperature regulation system

💭 Think About

• For each option, ask: Is the person usually still sweating, or have they stopped? How does that relate to their ability to lose heat? • Which condition is associated with very high body temperature, possible confusion or unconsciousness, and often dry or very hot skin? • Which of these conditions are earlier, milder stages where the body is still trying to cool itself effectively?

✅ Before You Answer

• Verify which condition is linked to failure of the body’s temperature-regulating center in the brain • Check which stage is commonly described as having hot, dry skin rather than profuse sweating • Confirm which conditions (cramps, exhaustion, prostration) usually still involve active sweating as the body attempts to cool down
