What is Heat Stroke?

Heat stroke occurs when the body's cooling system fails, and its internal temperature rises beyond the normal range. The body typically cools itself through sweating, but excessive heat or dehydration can overwhelm this mechanism. There are two primary types of heat stroke:

1. Classical Non-Exertional Heat Stroke: Most common in older adults, this type of heat stroke occurs due to prolonged exposure to high ambient temperatures, especially in poorly ventilated spaces during hot summer months.

2. Exertional Heat Stroke: This type is caused by a combination of high temperatures and physical activity. It often affects athletes or people engaging in strenuous outdoor activities, such as marathon runners or laborers in hot climates.

Understanding Heat Stroke: What Happens to Your Body?

Heat stroke occurs when the body’s temperature rises above 40°C (104°F). This extreme rise in body temperature disrupts the body’s ability to cool itself and can affect the central nervous system. As a result, the body stops responding properly to the heat, causing symptoms ranging from dizziness and nausea to more severe issues like unconsciousness or organ failure.

Signs and Symptoms of Heat Stroke

It’s vital to recognize heat stroke early. Some of the most common signs and symptoms include:

1. High Body Temperature: The hallmark symptom of heat stroke is a body temperature exceeding 40°C (104°F).

2. Hot, Dry Skin: Unlike heat exhaustion, which is often accompanied by sweating, heat stroke usually causes the skin to feel hot and dry, as the body stops sweating.

3. Nausea and Vomiting: As the body overheats, it can cause gastrointestinal distress, leading to nausea and vomiting.

4. Dizziness or Confusion: Heat stroke can affect your brain function, causing confusion, dizziness, and even loss of consciousness in severe cases.

5. Severe Headache: The pressure caused by high temperatures can result in a pounding headache.

6. Low Response Level: As the central nervous system is affected, the person may become lethargic or unresponsive.

7. Rapid Pulse and Breathing: As the body struggles to cool itself, the heart rate and breathing rate tend to increase rapidly.

8. Muscle Cramps: Prolonged heat exposure can cause dehydration, leading to painful muscle cramps.
