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 happens when the body's ability to regulate temperature fails under heat stress, causing core temperature to rise to about 40°C (104°F) or higher, typically with central nervous system signs like confusion, seizures, or unconsciousness. That 104°F point is the standard threshold because, at or above it, organs and brain start to malfunction and the risk of serious damage increases quickly. Lower temperatures such as 102, 101, or 100°F are more characteristic of milder heat-related illnesses (like heat exhaustion) or fever, where the CNS is not as severely affected. Normal body temperature is around 37°C (98.6°F), so reaching 104°F marks a dangerous escalation requiring urgent cooling and medical care.
