Which physiological risk arises if peripheral vasodilation happens prematurely during arousal from mammalian hibernation?

💡 Explanation

When vasodilation occurs prematurely during arousal from hibernation, the cold blood in the periphery rushes to the heart abruptly decreasing its temp causing arrhythmia because of disrupted ion channel function. Therefore cardiac arrest results, rather than, dehydration or hypoxic brain damage, which rely on different regulatory failures.
