What temperature-related emergency involves symptoms like weakness, dizziness, and nausea?

Heat exhaustion is a heat-related emergency that occurs when the body overheats, often due to prolonged exposure to high temperatures, intense physical activity in hot weather, or both. The symptoms associated with heat exhaustion include weakness, dizziness, nausea, headaches, excessive sweating, and sometimes confusion. This condition can be a precursor to more severe heat-related illnesses such as heatstroke, making it essential to recognize and address it promptly.

In heat exhaustion, the body's cooling mechanisms—such as sweating—are still functioning but are overwhelmed, leading to fluid loss and electrolyte imbalances. Immediate intervention can include moving the person to a cooler environment, providing rehydration with water or electrolyte drinks, and removing any excess clothing. Recognizing these symptoms early is crucial to prevent progression to a more dangerous condition like heatstroke, which can involve symptoms such as a high body temperature, altered mental state, and even loss of consciousness.
