Know the Difference to Stay Safe in Hot Weather

Heat Exhaustion vs. Heat Stroke

As the temperature rises, the risk of heat-related illnesses becomes a concern, particularly during hot summer months or in regions with high temperatures. Heat exhaustion and heat stroke are two such conditions that can occur due to prolonged exposure to extreme heat and humidity. In this blog, we will delve into the differences between heat exhaustion and heat stroke, including their causes, symptoms, and essential first aid measures.

Heat Exhaustion

Heat exhaustion is a milder form of heat-related illness caused by the body’s inability to cool down efficiently. It often occurs when individuals are exposed to high temperatures for extended periods, leading to excessive sweating and dehydration. Heat exhaustion is a serious condition and requires prompt attention to prevent it from progressing to heat stroke.

Causes of Heat Exhaustion

1. High Temperatures: Exposure to hot and humid weather, especially without adequate rest or shade, can trigger heat exhaustion.

2. Strenuous Physical Activity: Engaging in intense exercise or physical labor in the heat can contribute to heat exhaustion, as it leads to increased sweating and fluid loss.

3. Dehydration: Insufficient fluid intake can reduce the body’s ability to cool down through sweating, increasing the risk of heat-related illnesses.

Symptoms of Heat Exhaustion

1. Heavy sweating and clammy skin

2. Weakness or fatigue

3. Dizziness or lightheadedness

4. Headache

5. Nausea or vomiting

6. Rapid heartbeat

7. Muscle cramps or weakness

8. Cool, moist skin despite the heat

First Aid for Heat Exhaustion

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

1. Move them to a cool, shaded area or an air-conditioned space.

2. Have them lie down and elevate their feet slightly to improve blood flow to the brain.

3. Encourage the person to drink cool, non-alcoholic fluids (e.g., water or sports drinks).

4. Apply cool, wet cloths or use a fan to help lower their body temperature.

5. If symptoms persist or worsen, seek medical attention immediately.

Heat Stroke

Heat stroke is a severe and life-threatening heat-related illness that requires immediate medical attention. Unlike heat exhaustion, heat stroke is characterized by the body’s inability to regulate its temperature, resulting in a rapid increase in body temperature.

Causes of Heat Stroke

1. Prolonged Heat Exposure: Staying in hot environments for too long without adequate hydration and cooling measures can lead to heat stroke.

2. Ignoring Heat Exhaustion Symptoms: When heat exhaustion is left untreated or ignored, it can progress to heat stroke.

3. High Humidity: High humidity can impede the body’s ability to cool down through sweating, increasing the risk of heat stroke.

Symptoms of Heat Stroke

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

2. Altered mental state or confusion

3. Hot, dry skin (absence of sweating)

4. Rapid and strong pulse

5. Nausea, vomiting, or diarrhea

6. Seizures or convulsions

7. Unconsciousness or coma

First Aid for Heat Stroke

Heat stroke is a medical emergency. If you suspect someone has heat stroke, take the following steps:

1. Call emergency services immediately.

2. Move the person to a cool, shaded area.

3. Remove excess clothing and attempt to lower their body temperature with cool water or wet towels.

4. Do NOT give them anything to drink if they are unconscious or unable to swallow.

Preventing Heat-Related Illnesses

1. Stay hydrated by drinking plenty of fluids, even if you don’t feel thirsty.

2. Avoid strenuous outdoor activities during the hottest part of the day.

3. Wear lightweight, light-colored, and loose-fitting clothing.

4. Take regular breaks in shaded or air-conditioned areas during hot weather.
