Which physiological risk increases when a hibernating mammal experiences frequent arousal during its hibernation period?

💡 Explanation

When a hibernating mammal experiences frequent arousals, it engages in thermogenesis causing rapid metabolic increase and excessive usage of brown fat reserves due to increased mitochondrial uncoupling. Therefore, brown fat depletion results, rather than edema, arrhythmia, or atrophy requiring different long term physilogical changes.
