Quick Answer
Heat stroke symptoms can be mistaken for heat exhaustion, but they are distinct conditions. Key differences include body temperature, level of consciousness, and sweating.
Identifying Heat Stroke Symptoms
Heat stroke is a life-threatening condition characterized by a body temperature of 103°F (39.4°C) or higher. To identify heat stroke, look for a lack of sweating, despite the high temperature. Other symptoms include confusion, agitation, and loss of consciousness. In severe cases, heat stroke can cause seizures, coma, and even death.
Distinguishing Heat Stroke from Heat Exhaustion
Heat exhaustion, on the other hand, is a milder condition that can progress to heat stroke if left untreated. Symptoms of heat exhaustion include heavy sweating, pale skin, fast and weak pulse, nausea or vomiting, and dizziness or fainting. To distinguish heat exhaustion from heat stroke, check the body temperature, which is usually below 103°F (39.4°C). If the body temperature is normal or only slightly elevated, the condition is likely heat exhaustion.
Prevention and Treatment
Preventing heat-related illnesses requires awareness and caution. When working or exercising in hot environments, drink at least 8-10 glasses of water per day, take regular breaks in shaded areas, and avoid strenuous activities during the hottest part of the day (usually between 11am and 3pm). If you or someone else is experiencing symptoms of heat exhaustion or heat stroke, seek shade or air-conditioning immediately and rest in a comfortable position. Remove excess clothing and apply cool compresses to the skin. In severe cases, call for emergency medical assistance.
