Heat exhaustion is a condition that occurs when the body overheats. Its signs and symptoms include heavy sweating and a rapid pulse, both a result of your body overheating. Heat exhaustion is one of three heat-related syndromes, with heat cramps being the mildest and heatstroke being the most severe. Keep reading to learn heat exhaustion causes, when to see the doctor, who’s at risk, heat exhaustion treatment and heat exhaustion prevention.

What is normal core body temperature? 

Heat exhaustion results when your body fails to cool down and maintain a normal core temperature. If left untreated, it can lead to heat stroke, a potentially fatal condition that needs medical intervention. 

Your body’s heat combined with environmental heat results in what’s called your core temperature, your body’s internal temperature. Your body needs to regulate the heat gain (and in cold weather, heat loss) from the environment to maintain a normal core temperature, approximately 98.6 F (37 C).1 

Possible Heat Exhaustion Signs + Symptoms 

Here are some possible heat exhaustion signs and symptoms. 

  • Cool, moist skin with goosebumps in the heat, or clammy skin 
  • Heavy sweating 
  • Fainting 
  • Dizziness 
  • Thirst 
  • Fatigue 
  • Weak, rapid pulse 
  • Low blood pressure upon standing 
  • Muscle cramps 
  • Nausea, vomiting 
  • Headache 

Individuals with heat exhaustion will generally have an elevated body core temperature (internal temperature, not skin temperature).

When To See The Doctor 

If your signs and symptoms don’t improve within an hour, or if they worsen, contact your doctor or health care provider immediately. You need urgent medical attention if your core body temperature reaches 104F (40C). 

If you are with someone suffering from heat exhaustion, seek medical attention if their core temperature rises or if he or she is confused or agitated. 

Heat Exhaustion Causes 

The main cause of heat exhaustion is the failure of the body’s cooling mechanism (mainly evaporative sweating) to maintain a normal core body temperature, resulting in the body overheating. This can occur in adults, children, and as well as in animals (like, dogs and cats). The following factors can contribute to heat exhaustion. 

  • Strenuous work or exercise in a warm or hot environment 
  • Dehydration 
  • Alcohol intake 
  • Wearing clothing that inhibits evaporative cooling of the body.

Who’s At Risk 

The elderly and children under five years of age are at higher risk for developing heat exhaustion. Heat exhaustion can happen when dehydration occurs after a long heat spell especially when humidity is high. 

Heat Exhaustion Treatment: What To Do If You Experience Heat Exhaustion 

When heat exhaustion occurs, you need to immediately cool the body by rehydration. 

  • Drink plenty of fluids. Avoid carbonated or alcoholic drinks. 
  • Coconut water is a cooling fruit that can do wonders to help keep you hydrated. 
  • Stop all activity and take a rest. The person affected should be transferred to a cool and shady place, preferably into air conditioning if available. 
  • Make the person lie down with legs elevated above the heart. 
  • Cooling can be aided by spraying cool water on the skin and then circulating the air with fans to increase evaporative cooling. A cool water shower may also help. 
  • Wear loose-fitting, lightweight, natural fabrics. 
  • Provide the person with cool drinks such as electrolytes, lemonade, and coconut water. Coconut water is a natural source of electrolytes and low on the glycemic index. 
  • Additionally, intravenous fluids may be given by medical personnel to treat dehydration if needed. 

People with high Pitta dosha need to be particularly vigilant about keeping their bodies cool. The main element in Pitta dosha is fire so they get heated easily. To avoid damaging their internal organs, Pitta Prakriti (Pitta body types) should take special care to not get overheated. Not only Pitta body types can be affected. Others should also take precautions to avoid heat exhaustion. If neglected, the condition might cause severe consequences. Vata body types also need special care as they are easily dehydrated.

Heat Exhaustion Prevention 

You can take several precautions to prevent heat exhaustion and other heat-related illnesses. 

  • When temperatures rise, wear loose-fitting, lightweight clothing. Wearing excess clothing or clothing that fits tightly won’t allow your body to cool properly. 
  • Protect against the sun. Avoid the midday sun. Sunburn affects your body’s ability to cool itself. Protect yourself outdoors with a wide-brimmed hat and sunglasses and use a broad-spectrum sunscreen. Avoid going out in the midday sun when the sun’s rays are most intense. 
  • Drink plenty of fluids. Staying hydrated will help your body sweat and maintain a normal body temperature. 
  • Never leave anyone in a parked car. This is a common cause of heat-related deaths in children. When parked in the sun, the temperature in your car can rise 20 degrees Fahrenheit (more than 6.7 C) in 10 minutes. 
  • Try to schedule exercise or physical labor for cooler parts of the day, such as early morning or evening. Limit time spent working or exercising in the heat. 
  • Be cautious if you’re on any medication. If you take medications or have a condition that increases your risk of heat-related problems, such as a history of previous heat illness, avoid the heat and act quickly if you notice symptoms of overheating. 
  • Avoid excessive salty, spicy, sour, hot, and pungent food. Avoid hot beverages as it is unbalancing for Pitta dosha. 
  • Avoid skipping meals, but do not overeat. Take light meals and do not get dehydrated. 
  • Drink coconut water. It’s great for hydration and neutralizes acid so it can also help with heartburn and acid reflux. 
  • When it comes to exercise, especially during the Pitta season, don’t over-exert yourself, especially by running in the hot afternoon sun. Reduce anything that heats the body. That includes saunas, steam rooms, hot showers, and hot spicy foods. Stay out of the hot midday sun. 
  • Take walks in the cool mornings or evenings under the moonlight after dinner. Do deep breathing exercises and meditation. Enjoy the following cooling recipes to stay hydrated in the heat.
