Which mechanism causes elevated core temperature when vasodilation during hyperthermia becomes impaired within mammalian skin?

💡 Explanation

When vasodilation becomes impaired, reduced convective heat dissipation from the skin occurs because blood flow to capillary beds near the skin surface is restricted, hindering heat transfer to the environment. Therefore, reduced convective dissipation causes elevated core temperatures, rather than metabolic increases, radiative heat absorption, or evaporative decrease which involve distinct thermal regulation pathways.
