Heat stroke core temperature threshold is typically what?

Heat stroke core temperature threshold is typically what?

• A. 102 F
• B. 100 F
• C. 101 F
• D. 104 F

Answer: (D)

Heat stroke hinges on a failure of the body's cooling system that lets the core temperature rise to dangerous levels. The typical threshold used is 104°F (40°C). Reaching this level, especially with central nervous system changes such as confusion, seizures, or loss of consciousness, signals heat stroke and calls for immediate cooling and medical care. Lower heat-related illnesses, like heat exhaustion, usually have core temperatures around 100–102°F and lack CNS impairment. Core temperature should be measured with a reliable method (like rectal or ingestible thermometry) since skin readings can be misleading.
