Why does hyperthermia accelerate exponentially once the body's core temperature surpasses 41°C, even if the external temperature remains constant?

💡 Explanation

Hyperthermia escalates rapidly due to protein denaturation; because crucial cellular proteins, including those involved in thermoregulation, become non-functional as temperature increases. Therefore, the body's ability to dissipate heat declines further, rather than cell respiration efficiency increasing or glycogen breakdown directly lowering ATP production.
