Epigenetic Aging Slows During Hiberation in a Common Bat Species

In conclusion, application of a multi-species bat epigenetic clock provides strong evidence that hibernation is associated with slower epigenetic ageing. The multi-species clock explains 94% of the variation in the chronological ages of both hibernating and non-hibernating big brown bats; however, the clock estimates are equal to or greater than the chronological age, suggesting big brown bats age slightly faster than a 'typical' bat, especially during the active period.
