What action should you avoid when attending to a person suspected of having heat exhaustion?

When attending to a person suspected of having heat exhaustion, covering the head and neck to retain body heat is a counterproductive action. Heat exhaustion occurs when the body loses excessive amounts of water and salt, primarily due to prolonged exposure to high temperatures and vigorous physical activity. The symptoms can include heavy sweating, weakness, dizziness, and nausea.

To effectively address heat exhaustion, the focus should be on cooling the individual down and rehydrating them. Providing water helps replenish lost fluids, while moving the person to a cooler environment helps lower their body temperature, alleviating the symptoms. Laying the person down is important as it can help prevent fainting and allow for better circulation. Conversely, covering the body will trap heat and exacerbate the condition, making A the action that should be avoided.
