Heat Stroke vs. Heat Exhaustion: Know the Difference

Heat Exhaustion

As temperatures rise, the risk of heat-related illnesses becomes a critical concern. Among these, heat stroke and heat exhaustion are two of the most severe. Understanding the differences between them is crucial for timely and effective intervention.

Heat exhaustion is the body’s response to excessive loss of water and salt, typically through sweating. Key symptoms include:

  1. Heavy sweating
     
  2. Weakness or fatigue
     
  3. Dizziness
     
  4. Nausea or vomiting
     
  5. Muscle cramps
     
  6. Headache
     
  7. Fainting
     
  8. Pale, cool, and moist skin

Immediate steps for treating heat exhaustion include:

  1. Move to a cooler environment: Preferably indoors or at least in the shade.
     
  2. Hydrate: Drink plenty of water or electrolyte beverages.
     
  3. Rest: Lie down and elevate legs slightly to improve circulation.
     
  4. Cool down: Apply cool, wet cloths to the body or take a cool shower.

Heat Stroke

Heat stroke is a severe condition resulting from prolonged exposure to high temperatures, leading to the body’s inability to regulate its temperature. It is a medical emergency.

Symptoms include:

  1. High body temperature (above 103°F or 39.4°C)

  2. Hot, dry skin or profuse sweating (in exertional heat stroke)
     
  3. Altered mental state or behaviour (confusion, agitation, slurred speech)
     
  4. Seizures
     
  5. Loss of consciousness
     
  6. Rapid and strong pulse
     
  7. Nausea or vomiting

Immediate action is critical for heat stroke:

  1. Call emergency services: Heat stroke requires immediate medical attention.
     
  2. Cool the person: Move them to a cooler place and use any means available to cool them rapidly—immerse in cool water, place ice packs on the neck, armpits, and groin, or use fans and cool cloths.
     
  3. Do not give fluids: Unlike heat exhaustion, administering fluids can be dangerous if the person is not fully conscious.

Recognize and Respond to Stay Safe
