What is the Difference Between Heat Stroke and Heat Exhaustion?

Heat stroke and heat exhaustion are both heat-related illnesses that occur when the body is unable to cool itself adequately. They share some similarities but have distinct differences in symptoms and severity.

Heat Exhaustion:

• Characterized by heavy sweating
• Symptoms include dizziness, headache, nausea, weakness, unsteady gait, muscle cramps, and fatigue
• Core body temperature is between 101°F (38.3°C) and 104°F (40°C)
• Less severe condition, but if left untreated, it can lead to heat stroke

Heat Stroke:

• Characterized by decreased sweating
• Symptoms include a change in mental status (confusion, delirium, combativeness, seizures, loss of consciousness), core body temperature above 104°F (40°C), rapid heart rate, no sweating, and nausea or vomiting
• Most severe heat-related illness, posing a serious medical emergency
• Requires immediate medical attention; call 911 and take steps to lower the person's body temperature by moving them to a cooler place, using cold compresses, and not giving them fluids

To prevent heat exhaustion and heat stroke, it is essential to stay hydrated, wear appropriate clothing, avoid overexertion in hot weather, and seek cooler environments when needed.

Comparative Table: Heat Stroke vs Heat Exhaustion

Here is a table comparing the differences between heat stroke and heat exhaustion:

Both heat exhaustion and heat stroke are potentially serious conditions that can occur when a person's body temperature rises too much. If left untreated, heat exhaustion can lead to heat stroke, which can be life-threatening. It is essential to recognize the early warning signs of heat exhaustion, such as nausea, light-headedness, and muscle cramping, and take appropriate action to cool the body down. If a person is experiencing heat stroke, it is crucial to call emergency services immediately and take steps to lower their body temperature.
