Heat stroke and heat exhaustion are two distinct heat-related conditions with varying degrees of severity. Heat exhaustion is typically the precursor to heat stroke and occurs when the body becomes overwhelmed by excessive heat. Symptoms include heavy sweating, weakness, dizziness, and nausea. Prompt action, such as moving to a cooler environment, resting, and hydrating, can prevent progression to heat stroke. Heat stroke, on the other hand, is a medical emergency and requires immediate attention. It involves a dangerous elevation in body temperature, accompanied by a cessation of sweating, confusion, rapid heartbeat, and even loss of consciousness. Heat stroke demands urgent medical intervention to prevent life-threatening complications.
