Which risk notably increases when a hibernating groundhog experiences intermittent arousals during unusually warm winter periods?

💡 Explanation

When hibernating animals experience frequent arousals, metabolic rate surges due to shivering thermogenesis because the animal tries to revert to homeothermy, rapidly depleting the finite energy stored as fat. Therefore, depletion of fat reserves is increased, rather than infection, cognitive impairment, or combustion, which involve pathogen exposure, neural disruptions, or highly unusual reactions.
