8/25/2023 0 Comments Do bears hibernateAlso when the spring comes they only wake up when is sure to find enough food to survive. The reserves of fat that they build during summer and fall are just enough so the bears can survive the winter, therefore for them to wake up and start looking for food in the middle of the winter is quite dangerous: this is consuming a lot of their low reserves of energy and if they don’t find food they can die in few days. During bears’ torpor the temperature drops to 29☌ – 34☌. Normal temperature of Carpathians’ brown bear range between 36.5☌ and 37.5☌. Also their body temperature drops only slightly, while in hibernation there is a drastic change in body temperature. Brain activity also doesn’t slow down, but goes into a state of permanent awakeness, therefore the bear can wake up at slightest noise. However, vital functions like breathing and blood circulation continue almost unchanged. In a deep sleep (remember is called “torpor”) most of body functions have reduced activity. Similarly an animal hibernating will use almost no energy, drastically reduce all metabolism and wake up slowly. Think like that: a computer hibernation will save all docs on disk and allows the laptop to use zero power. Yes, there is: as with your windows operated computers (sorry, Apple fans, we’re just trying to explain some things here ), deep sleeping is a light version of hibernation. Wait, what? There is a difference between hibernation and sleep? We should not use the word hibernation because the brown bear (Ursus Arctos) doesn’t really hibernate, but go into a deep sleep, called torpor. And if you think that doing nothing is an amazing way to burn fat,, don’t forget that that means not eating either. They will burn it by doing nothing all winter. As opposite to us humans, bears are not unhappy to build fat. And here’s why:ĭuring winter, starting with late October or November, depending on weather conditions, bears are sleeping and living out of the fat they accumulate during summer. The chances to see bears in the wilderness (as all our bear viewing tours are) during winter are very low. Another question we get is ”What are the chances of seeing them in Romania?” As you can see in the picture below, sometimes it’s possible. People coming to Brasov during winter months are always curious if it’s possible to see these wild animals during wintertime. ”Do bears hibernate during winter?” is one question we get when we have guests coming to our bear watching tour.
