Quick Answer
Heat exhaustion and heatstroke are two severe heat-related illnesses with distinct differences. In heat exhaustion, the body is able to cool itself, whereas heatstroke occurs when the body's ability to cool itself is impaired. Heat exhaustion is often reversible with proper treatment.
Identifying Key Differences
Heat exhaustion and heatstroke share similar symptoms, such as heavy sweating, pale or flushed skin, and rapid pulse. However, heatstroke is characterized by a body temperature of 103°F (39.4°C) or higher, often with a temperature difference of 1.5°F (0.8°C) between the armpits and groin. In heat exhaustion, the body temperature remains below 103°F (39.4°C).
Cooling Methods for Heat Exhaustion
For heat exhaustion, cool the body by moving to a shaded area, removing excess clothing, and applying cool compresses or a fan. You can also use a cool shower or bath, but avoid using ice or ice water, as this can cause a rapid drop in body temperature. To cool a person experiencing heat exhaustion, spray them with cool water and fan them, aiming for a temperature drop of 1.5°F (0.8°C) per 15 minutes.
Preventing Heat-Related Illnesses
Prevention is key when it comes to heat-related illnesses. Stay hydrated by drinking plenty of water or electrolyte-rich beverages, such as sports drinks. Avoid strenuous activities during the hottest part of the day (usually between 11am and 3pm) and take regular breaks in shaded areas. Wear lightweight, light-colored clothing and a hat to protect yourself from the sun. Additionally, monitor the weather forecast and plan outdoor activities accordingly. If you have underlying health conditions, take extra precautions to stay safe in the heat.
