🔍 Key Concepts

• Heat exhaustion vs. heat stroke – how the body responds to working in high temperatures • Role of body fluids and electrolytes (salt) in temperature regulation • Difference between too much water, too little water/salt, and change in body temperature

💭 Think About

• When someone works hard in a hot environment, what is happening to their sweat, body water, and salt levels? • Does heat exhaustion come more from the body gaining heat, or from what the body loses while trying to get rid of heat? • Which option best explains why a person might feel weak, dizzy, and have muscle cramps after sweating heavily in the heat?

✅ Before You Answer

• Identify which options involve loss vs. gain of heat in the body • Check which option mentions both water and salt, not just one or the other • Eliminate any option that describes a condition more like hypothermia (low body temperature) than overheating
