Quick Answer
Watch for symptoms such as dizziness, nausea, headaches, fatigue, and rapid heartbeat in heat-related illnesses. Be particularly aware of signs of heat exhaustion like heavy sweating, pale skin, and a weak pulse. If left untreated, heat exhaustion can quickly progress to heatstroke, a life-threatening condition.
Recognizing Heat-Related Illnesses
Heat-related illnesses often manifest with mild to severe symptoms. Heat exhaustion is a common precursor to heatstroke. Be aware of these warning signs: heavy sweating, pale or flushed skin, a weak or rapid pulse, dizziness, nausea, headaches, fatigue, and irritability. If you or someone else is experiencing any of these symptoms, seek shade or air-conditioning and rest immediately.
Treating Heat-Related Illnesses
In cases of heat exhaustion, encourage the person to drink cool water or an electrolyte-rich beverage. If the individual is conscious, remove excess clothing, and provide a cool compress to the forehead, neck, and wrists. Monitor the person’s temperature and pulse, and if they worsen or the individual becomes unconscious, call for emergency medical help.
Cooling Methods and Hydration
To prevent heat-related illnesses, stay hydrated by drinking at least 1 gallon of water per day in extreme heat. Avoid strenuous activities during the hottest part of the day (11 am to 3 pm). Practice cooling techniques like fanning, taking cool showers, or using a wet towel to cool down. If the temperature exceeds 90°F (32°C), avoid using fans, as they can actually make you feel warmer.
