Quick Answer
To treat heat exhaustion in the field, remove excess clothing, cool the body with shade or cool water, and replenish electrolytes with oral rehydration solutions. Monitor vital signs closely and seek medical attention if symptoms worsen. Administer cool compresses to the neck, wrists, and forehead.
Identifying Heat Exhaustion Symptoms
Heat exhaustion can be identified by heavy sweating, pale or flushed skin, fast and weak pulse, nausea or vomiting, dizziness or fainting, headaches, and fatigue. In a field setting, it’s essential to recognize these symptoms early to prevent heat exhaustion from progressing to heatstroke.
Cooling Methods
Cool the body using the “Wet Towel Method” - wet a towel with cool water, wring it out, and place it on the forehead, neck, and wrists. Replace the towel every 2-3 minutes. Another method is to use a cooling vest or a cooling scarf, which can be soaked in water and wrung out to lower the body temperature. In extreme cases, immerse the person in a cool water bath, but be cautious not to cool them too quickly, as this can cause shock.
Rehydrating and Replenishing Electrolytes
Provide the person with oral rehydration solutions, such as sports drinks or coconut water, every 15-20 minutes to replenish lost electrolytes. Aim to give 1-2 cups of fluid every 15 minutes. Monitor urine output and color to ensure proper rehydration. If urine is dark yellow or amber-colored, rehydration is not adequate. Also, consider administering electrolyte tablets or powders to the oral rehydration solution to replenish sodium and potassium.
