Why does impaired hypothalamic function cause hypothermia despite normal shivering reflexes in a patient?

💡 Explanation

The hypothalamus sets the body's thermoregulatory set point, and its impairment causes a lower threshold for initiating vasoconstriction, because signals to conserve heat are compromised; therefore, the body attempts to maintain the lowered set point rather than initiating heat conservation, rather than shivering being ineffective.
