Which physiological outcome occurs when a hibernating mammal experiences vasodilation in its superficial tissues?

💡 Explanation

When vasodilation occurs in superficial tissues, increased blood flow allows heat to radiate outwards, raising core temperature and triggering arousal because the hypothalamus senses rising temp and begins metabolic normalization. Therefore rapid arousal results, rather than decreased metabolic rate, heat conservation, or suppressed thermogenesis which require continued hibernation mechanisms.
