Dizziness, headache, and nausea are all signs of which heat-related condition?

• A. Heat stroke
• B. Heat cramps
• C. Heat Exhaustion
• D. Heat failure

Answer: (C)

Overheating with fluid loss stresses the body’s cooling system, and dizziness, headache, and nausea are classic signs of heat exhaustion. When you sweat a lot and don’t replace fluids and salts, blood volume drops, which reduces blood flow to the brain and can make you feel lightheaded or nauseated. You may also feel tired, weak, or clammy, and you might have a slight fever or feel faint. This condition is milder than heat stroke, which is an emergency and involves dangerous brain and organ dysfunction, often with confusion, very high body temperature, and sometimes hot, dry skin. Heat cramps, on the other hand, are painful muscle cramps caused by electrolyte imbalances and dehydration, usually during heavy sweating. If heat exhaustion is suspected, the priorities are to cool the body and rehydrate: move to a shaded or air-conditioned area, remove excess clothing, sip water or an electrolyte drink, and apply cool compresses or a fan. Seek medical help if symptoms worsen or you experience vomiting, confusion, chest pain, or new or increasing dizziness.
