Hibernation: Not a Snooze

This Stuff You Should Know episode dives deep into the fascinating world of hibernation, exploring how animals dramatically slow their bodies down to survive harsh winters and food shortages. Josh and Chuck break down the surprising differences between hibernation and regular sleep, explaining the wild physiological changes that occur—like how some animals' heart rates drop from hundreds of beats to just a handful per minute, and how certain creatures can actually recycle their own urine for survival. They also explore whether humans might someday tap into this ancient survival mechanism, touching on everything from Russian peasants' winter survival strategies to NASA's interest in hibernation technology for long-distance space travel.
