What is Heat Exhaustion?

Heat exhaustion is a heat-related illness resulting from your body’s inability to regulate its temperature effectively. Excessive sweating leads to a significant loss of fluids and electrolytes (like sodium and potassium), disrupting the body’s delicate balance. While less severe than heatstroke, heat exhaustion is still a serious condition that requires immediate attention. Untreated, it can rapidly escalate into heatstroke, a medical emergency with potentially fatal consequences.

Common Symptoms of Heat Exhaustion: Recognizing the Warning Signs

  • Heavy Sweating: Profuse sweating is a hallmark sign.
  • Cool, Clammy Skin: Skin might feel cool and damp, appear pale, ashen, or flushed.
  • Headache: A throbbing headache, often with dizziness or lightheadedness.
  • Dizziness or Fainting: Feeling lightheaded, dizzy, or fainting due to dehydration.
  • Fatigue and Weakness: Extreme fatigue and weakness.
  • Nausea and Vomiting: Feeling nauseous or vomiting.
  • Muscle Cramps: Painful muscle cramps, particularly in the arms, legs, or stomach.
  • Rapid Heartbeat (Tachycardia): Rapid heartbeat, weak pulse.
  • Rapid Breathing (Tachypnea): Rapid and shallow breathing.
  • Elevated Body Temperature: Slightly elevated (above 100°F or 37.8°C), but usually below 104°F (40°C).
  • Excessive Thirst: Intense thirst.
  • Low Blood Pressure (Hypotension): Noticeable drop in blood pressure.
  • Blurred Vision: Temporary blurred vision.
  • Swollen Extremities (Heat Edema): Swelling in ankles, feet, or hands.
  • Transient Confusion: Brief periods of confusion or disorientation.

Heat Exhaustion Symptoms in Babies and Young Children: Special Considerations

Babies and young children are particularly vulnerable. Parents should be vigilant for paler skin, cooler skin temperature, increased thirst, and irritability.

When to Seek Immediate Medical Attention

  • Symptoms don’t improve after an hour of rest and rehydration.
  • Cannot drink fluids.
  • Body temperature of 104°F (40°C) or higher.
  • Trouble speaking, standing, or walking.
  • Continues sweating heavily despite resting.
  • Confused or distressed.
  • Loss of consciousness.

Treating Heat Exhaustion: First Aid and Prevention

  1. Move to a Cool Place: Get the person out of the heat.
  2. Remove Excess Clothing: Loosen or remove restrictive clothing.
  3. Cool the Body: Apply cool, wet cloths to the skin.
  4. Hydrate: Offer water, electrolyte solutions, or clear broths.
  5. Monitor Vital Signs: Keep a close eye on temperature, pulse, and breathing.
  6. Rest: Encourage complete rest.

Preventing Heat Exhaustion: Proactive Measures

  • Stay Hydrated
  • Dress Appropriately
  • Limit Exposure to Heat
  • Use Sunscreen
  • Take Breaks
  • Acclimatize Gradually
