Heat exhaustion is a form of heat-related illness that can occur when the body cannot cool itself effectively. Heat exhaustion can be caused by a combination of factors, including high temperatures, high humidity, and physical exertion. Therefore, it is important to recognize the signs and symptoms of heat exhaustion and take appropriate action to prevent it from progressing to a more serious condition, such as heat stroke.

Cause: Heat exhaustion is caused by prolonged exposure to high temperatures and inadequate hydration. When the body is unable to cool itself effectively, it can lead to heat exhaustion. Other factors contributing to heat exhaustion include high humidity, physical exertion, and certain medications or medical conditions.

Symptoms: The symptoms of heat exhaustion can vary but may include heavy sweating, weakness, headache, nausea, dizziness, fainting, muscle cramps, rapid heartbeat, dark-colored urine

First Aid: If you suspect someone is suffering from heat exhaustion, it is important to take immediate action. The following steps should be taken to help the person:

  1. Move the person to a cool, shaded area.
  2. Have the person lie down and elevate their feet.
  3. Remove any excess clothing.
  4. Provide the person with cool, non-alcoholic beverages.
  5. Apply cool, wet clothes to the skin.
  6. Monitor the person’s vital signs, such as pulse and temperature.
  7. Seek medical attention if the person’s condition does not improve.

It is important to take heat exhaustion seriously and take steps to prevent it from occurring. This includes staying hydrated, wearing light-colored clothing, avoiding strenuous activity during the hottest part of the day, and taking frequent breaks in a cool, shaded area.
