Heatstroke vs. Heat Exhaustion: Signs, Symptoms, and First Aid

August 19, 2024

As temperatures rise, so do the risks of heat-related illnesses like heatstroke and heat exhaustion. Understanding the differences between these conditions, recognizing their signs and symptoms, and knowing the appropriate first aid measures can be lifesaving. At AFC West Haven, we prioritize your health and safety, especially during the hot summer. Here’s a comprehensive guide to help you stay informed and prepared.

Understanding Heat-Related Illnesses

Heat-related illnesses occur when the body cannot properly cool itself, leading to high temperatures. Two of the most common and severe conditions are heat exhaustion and heatstroke.

What is Heat Exhaustion?

Heat exhaustion is a condition that results from prolonged exposure to high temperatures, particularly when combined with high humidity and strenuous physical activity. It’s often caused by excessive sweating, which leads to dehydration and the depletion of essential salts and minerals.

Signs and Symptoms of Heat Exhaustion:

  • Heavy sweating
  • Weakness or fatigue
  • Dizziness or lightheadedness
  • Nausea or vomiting
  • Muscle cramps
  • Pale, calm, and clammy skin
  • Rapid but weak pulse
  • Headache
  • Fainting

What is Heatstroke?

Heatstroke is a severe, life-threatening condition when the body’s temperature regulation system fails. It is a medical emergency that requires immediate attention. Heatstroke typically develops from untreated heat exhaustion but can occur suddenly without prior symptoms.

Signs and Symptoms of Heatstroke:

  • High body temperature (104°F or higher)
  • Hot, dry, or slightly moist skin
  • Rapid and strong pulse
  • Confusion, agitation, or irritability
  • Slurred speech
  • Seizures
  • Loss of consciousness
  • Throbbing headache
  • Nausea or vomiting

Critical Differences Between Heat Exhaustion and Heatstroke

Understanding the critical differences between heat exhaustion and heatstroke is crucial for timely and appropriate response:

  • Body Temperature: Heat exhaustion generally involves a body temperature below 104°F, while a body temperature of 104°F or higher characterizes heatstroke.
  • Skin Condition: During heat exhaustion, the skin may be cool, pale, and clammy. In heatstroke, the skin is hot and dry or slightly moist.
  • Mental State: Heat exhaustion can cause dizziness and fainting, but heatstroke can lead to confusion, agitation, seizures, and loss of consciousness.

First Aid for Heat Exhaustion

If you suspect someone is experiencing heat exhaustion, take the following steps:

  • Move to a Cooler Environment:
    • Get the person out of the heat and into an air-conditioned or shaded area.
  • Hydrate:
    • Encourage the person to drink cool water or sports drinks containing electrolytes. Avoid caffeine and alcohol.
  • Cool Down:
    • Apply cool, wet cloths to the skin, or have the person take a cool shower or bath.
  • Rest:
    • Allow the person to rest and avoid strenuous activity until they fully recover.
  • Monitor:
    • Keep an eye on their symptoms. See medical attention if they worsen or do not improve within an hour.

First Aid for Heatstroke

Heatstroke is a medical emergency. If you suspect someone is suffering from heatstroke, act quickly:

  • Call 911:
    • Immediately dial emergency services.
  • Cool the Person:
    • Move them to a more relaxed place and remove excess clothing.
    • Use whatever means to cool them down quickly, such as a cool bath, wet cloths, or ice packs applied to the armpits, neck, and groin.
  • Monitor Vital Signs:
    • While waiting for emergency responders, monitor their breathing, pulse, and level of responsiveness.
  • Stay with the Person:
    • Remain with them until medical help arrives, providing reassurance and continued cooling measures.

Prevention Tips for Heat-Related Illnesses

Prevention is critical to avoiding heat-related illnesses. Here are some tips to stay safe during hot weather:

  • Stay Hydrated: Drink fluids, especially water, throughout the day.
  • Wear Appropriate Clothing: Choose lightweight, light-colored, and loose-fitting clothing.
  • Limit Sun Exposure: Avoid direct sunlight and seek shade during peak heat hours (10 AM to 4 PM).
  • Use Sunscreen: Protect your skin from harmful UV rays with a high-SPF sunscreen.
  • Take Breaks: If you engage in outdoor activities, take frequent breaks in a cool or shaded area.
  • Acclimate: Gradually increase your exposure to high temperatures over several days to allow your body to adjust.
  • Avoid Strenuous Activity: Limit physical exertion during the hottest parts of the day.
