What are the symptoms of heat exhaustion?

Heat exhaustion occurs when the body loses an excessive amount of water and salt, typically due to prolonged exposure to high temperatures or intense physical activity in a hot environment. The symptoms reflect the body's struggle to cool itself and maintain normal function.

Low blood pressure and a weak pulse are indeed symptoms associated with heat exhaustion. When the body is overheating, it may lead to a decrease in blood pressure due to dehydration and loss of electrolytes, making it difficult for the heart to pump blood effectively. This can result in a weak pulse, as the heart works harder to maintain circulation under stressful conditions.

The other symptoms mentioned, such as severe headaches, nausea, fever, chills, extreme fatigue, and confusion, also characterize heat-related illnesses but do not directly pertain to the physiological response of low blood pressure and weak pulse, which specifically indicates the body's impaired ability to maintain proper circulation and hydration in heat exhaustion scenarios.
