Heat exhaustion is characterized by several symptoms that arise when the body loses excessive amounts of water and salt, typically due to prolonged exposure to high temperatures and physical exertion. Common symptoms include headache, nausea, fatigue, excessive sweating, and weakness.

Altered mental status generally signifies a more severe condition, such as heat stroke, where the body's thermoregulatory mechanisms are overwhelmed and can lead to neurological implications. In heat exhaustion, while individuals may feel dizzy or faint, it does not usually progress to an actual altered mental status.

Understanding these symptoms is crucial for identifying and managing heat-related illnesses effectively in a clinical setting, especially for those in high-risk environments such as flight nursing. Recognizing these differences allows for appropriate intervention and safety measures to be employed, ensuring the well-being of patients in potentially hazardous conditions.
