Hibernating mammals drastically lower their metabolic rate (MR) and body temperature (Tb) for up to several weeks. but regularly rewarm and stay euthermic for brief periods. It has been hypothesized that the necessity for rewarming is due to the accumulation or depletion of metabolites. or the accrual of cellular damage that can be eliminated only in the euthermic state. https://www.spidertattooz.com/USC-Trojans-9FIFTY-Snapback-Hat/
