Which physiological outcome occurs when a hibernating woodchuck experiences sudden ambient temperature rise?

💡 Explanation

When environmental temperature increases, vasodilation occurs because blood vessels widen to dissipate heat, leading to increased blood flow especially in peripheral tissues. Therefore vasodilation accelerates, rather than shutting down thermogenesis or sudden glucose release which involve different metabolic triggers during entry to or maintenance of torpor cycles.
