Don’t Let the Heat Get to You: How to Spot and Respond to Heat Exhaustion

With hotter days upon us, staying safe in the heat is more important than ever. Whether you’re exercising, working, or simply spending time outside, prolonged exposure to high temperatures can lead to heat exhaustion—a condition that’s often overlooked but potentially dangerous if left unaddressed. Here’s how to recognize the signs, take preventive steps, and know exactly what to do if you or someone nearby is affected by heat exhaustion.

What is Heat Exhaustion?

Heat exhaustion is a condition that occurs when your body overheats and struggles to cool itself down, usually due to prolonged exposure to high temperatures combined with inadequate hydration. The body cools itself by sweating, but this process can lead to dehydration and a drop in electrolyte levels, which are critical for muscle and nerve functions. If not managed quickly, heat exhaustion can progress to the more serious condition of heatstroke, which requires emergency medical care.

Common Causes of Heat Exhaustion

1. High Temperatures: Prolonged exposure to temperatures above 90°F, especially when combined with high humidity.
2. Physical Activity: Engaging in intense exercise or labor outdoors without adequate breaks or hydration.
3. Inadequate Hydration: Not drinking enough water can impair your body’s ability to regulate temperature.
4. Wearing Heavy Clothing: Thick, dark, or non-breathable clothing can trap heat.
5. Health Conditions or Medications: Some health conditions and medications (like diuretics) can increase the risk of dehydration.

Recognizing the Symptoms of Heat Exhaustion

Knowing the signs of heat exhaustion is crucial for timely intervention. The symptoms may vary but typically include:

• Heavy Sweating: The body’s attempt to cool itself can cause excessive sweating.
• Fatigue and Weakness: Feeling drained or weak is a common sign as the body’s energy reserves are depleted.
• Dizziness or Lightheadedness: Due to a drop in blood pressure from dehydration.
• Nausea or Vomiting: As the body struggles to maintain balance, nausea may set in.
• Headache: Dehydration often results in a headache.
• Cool, Clammy Skin: Despite the heat, skin may feel cold and clammy to the touch.
• Rapid, Weak Pulse: The heart works harder to pump blood to cool the body, leading to a weak but rapid pulse.

Remember, ignoring these signs may lead to heatstroke, a life-threatening emergency.

How to Prevent Heat Exhaustion

1. Stay Hydrated: Drink water frequently, especially if you’re outdoors or active. Aim for a glass of water every 20-30 minutes when in the sun.
2. Avoid Peak Heat Hours: Try to plan outdoor activities in the early morning or evening when temperatures are cooler.
3. Wear Lightweight, Breathable Clothing: Light-colored, loose, and moisture-wicking clothing helps keep your body cool.
4. Take Breaks: If you’re active outdoors, take regular breaks in shaded or air-conditioned areas to let your body cool down.
5. Know Your Limits: If you start feeling fatigued, dizzy, or otherwise unwell, listen to your body and stop your activity to rest.

Immediate Steps to Take for Heat Exhaustion

If you suspect someone is experiencing heat exhaustion, here’s what to do:

1. Move to a Cooler Area: Take the person to a shaded or air-conditioned space to help reduce their body temperature.
2. Hydrate Slowly: Offer small sips of water or a sports drink with electrolytes to rehydrate and replenish minerals lost through sweating.
3. Apply Cool Compresses: Use a damp cloth or cold pack on their forehead, neck, and wrists to help cool them down.
4. Loosen Clothing: Remove or loosen tight or heavy clothing to promote airflow and cooling.
5. Encourage Rest: Rest is essential for recovery. Avoid returning to activity too quickly, as this may cause symptoms to worsen.

When to Seek Medical Attention

If symptoms do not improve after 30 minutes of rest and cooling measures, seek medical assistance. Additionally, if the person shows signs of:

• confusion
• loss of consciousness
• rapid, strong pulse

they may be experiencing heatstroke. In this case, call emergency services immediately, as heatstroke is a medical emergency.

Heat Exhaustion Recovery Tips

After an episode of heat exhaustion, full recovery may take up to 24-48 hours. During this time:

• Continue to drink water to restore hydration.
• Avoid strenuous activities and exposure to high heat until fully recovered.
• Monitor for any recurring symptoms, as the body is more vulnerable to heat after an initial episode.
