00:02:48.240Instead of hibernating, bears fall into torpor, a deep sleep with some awareness still intact.
00:02:58.440During torpor, heart rate and breathing rate decreases, body temperature reduces slightly,
00:03:05.080and bears do not eat or release bodily waste.
00:03:09.460Bears can sleep more than 100 days without eating, drinking, or passing waste.
00:03:14.760Instead, bears are able to literally turn their pee into protein through a urea recycling process.
00:03:24.140The urea produced by their fat metabolism is broken down, and the nitrogen is reused by the bear to rebuild protein.
00:03:32.200The main difference between hibernation and torpor is that during torpor, the animal is able to wake up easily if hurt or threatened by predators.
00:03:42.280Pregnant female bears can also wake up from torpor to give birth, then go back to sleep afterwards.
00:03:49.600I am bear kin, so I gave up on hibernation and set my bleary sights on torpor.
00:03:57.780Energy is the currency. I can afford to waste none.
00:04:02.600Energy I used to waste becomes protein, becomes fuel.
00:04:07.440I keep just enough awareness to not miss something important.
