Quick Answer
Rapid cooling during heat emergencies is aided by techniques such as removing excess clothing, immersing the body in cool water, and using cool compresses or fans to cool the body. Evaporative cooling and misting can also help lower the body temperature. These methods should be done carefully and under medical supervision.
Cooling Techniques
When a person is experiencing a heat emergency, it’s essential to act quickly and effectively. Removing excess clothing can help cool the body by allowing air to circulate and heat to escape. In most cases, this means removing all clothing, including socks and shoes, to expose the skin to the air. The American Red Cross recommends cooling a person to 102.2°F (39°C) before calling for medical help.
Cooling Methods
Immersing a person in cool water is one of the most effective ways to cool the body. Water should be cool, not cold, as cold water can cause the blood vessels to constrict, which can worsen the situation. A good rule of thumb is to cool the person to 102.2°F (39°C) in 10-15 minutes. This can be done by submerging the person in a bathtub or pool filled with cool water, or by using a cooling blanket.
Precautions and Considerations
When using cooling techniques, it’s essential to take certain precautions. Avoid using ice or cold water, as they can cause the blood vessels to constrict. Also, avoid using fans or air conditioning alone, as they can blow warm air onto the person’s skin and make them feel worse. Finally, always cool a person at the onset of symptoms, rather than waiting for them to worsen.
