Quick Answer
Recognize heat exhaustion signs such as heavy sweating, pale skin, fast and weak pulse, nausea or vomiting, and dizziness or fainting. If left untreated, it can progress to heatstroke, a life-threatening condition.
Warning Signs of Heat Exhaustion
Identify heat exhaustion signs early to prevent heatstroke. Watch for heavy sweating, pale or flushed skin, and a rapid pulse. If the person experiences nausea or vomiting, dizziness, or fainting, seek medical attention immediately. Monitor their temperature, as heat exhaustion is characterized by a body temperature of 100.4°F (38°C) or lower.
Recognizing the Warning Signs in Various Situations
In hot and humid environments, be aware of the increased risk of heat exhaustion. Prolonged physical activity, even in mild temperatures, can cause heat exhaustion. Pay attention to individual factors such as obesity, age, and certain medical conditions that may increase the risk. In these situations, monitor individuals closely and provide regular breaks in shaded or air-conditioned areas.
First Aid for Heat Exhaustion
Move the affected person to a cooler location, remove excess clothing, and apply cool compresses or fans to lower their body temperature. Provide cool water or an electrolyte-rich drink to rehydrate. If the person’s symptoms worsen or they experience seizures, confusion, or a body temperature above 104°F (40°C), call for emergency medical services.
