The mysteries of nature, or Why the bear sleeps in winter

No matter how close a person is to nature, it still remains for him a huge unsolved mystery. This is especially true of animals. It is extremely interesting for people to observe the life and behavior of our "brothers" in the animal kingdom, the fate of which consists of numerous and difficult trials. So, mankind has long been trying to unravel the mystery of why the bear sleeps in winter. It's not a secret that severe winters are one of the most difficult periods in the life of many animals. Unsurprisingly, they are trying to hide, and they are triggered by the instinct of self-preservation. This is especially noticeable for bears, since the predator conducts cold times in hibernation, thus passing through frost and bad weather.

Features of the view

Winter hibernation is the main feature of bears. In fact, these are unique animals that are to some extent similar to dogs, but have a more developed body structure and can walk on their hind legs. Some of them prefer animal food, while others prefer vegetable food. Returning to the question of why the bear sleeps in winter, it should be noted that some species of animals spend the cold season in a pre-prepared den. Others, on the contrary, wander throughout the year.

The causes of winter sleep

We are interested in why the bear sleeps in winter. The main reasons for the unusual phenomenon are the following:

• An animal experiences huge difficulties in finding food, especially if it is a kind of bear that eats plants;
• The large size of the mammal creates difficulties in movement, as well as the search for the necessary "food" products in huge quantities;
• Eating constantly only animal food, a bear can not live long.

Therefore, the mammal instinctively goes into hibernation. Of course, there is a possibility that under the snow will be berries or other fruits, but they still can not moderate the famine of a five-kilogram beast. There are other assumptions about why bears sleep in winter. Female polar bear fall into hibernation while pregnant. This process can occur at any time of the year, but most often this happens in winter, as in adverse days the future "moms" try to keep their fruit as best as possible.

Autumn chores

Considering the interesting question of why the bear sleeps in winter, you can not tell about the period of preparation for bed. Naturally, before hibernation the animal needs to stock up on nutrients, accumulate a stock of fat deposits in order to successfully survive the harsh period. The most favorite delicacy of a bear is cedar cones, especially since they are considered to be the best nutritional food. Young males easily break off branches or climb on trees and tear off their favorite food. Some bears eat stocks made by small animals. Digging their mink, they find nuts, small rodents, eggs, larvae and much more. If the season turned out to be lean, the mammal may not fall into a hibernation, which will negatively affect its state of health.

How's it going?

After preparation the animal falls into a long hibernation, which can last several months and even six months. It is very interesting to learn about how bears sleep in winter and why they suck paws. When the mammal has fallen asleep, its body begins to completely rebuild, resulting in breathing becomes less frequent, and the heart rate slows down. It should be noted that charming animals rather doze than sleep soundly, so they can easily be awakened. In this case, the bear will be very angry and dissatisfied with the fact that he was disturbed. Sucks a mammal paw because on its limbs there is a kind of "moult". A very thick layer of skin is located on the soles of the feet, which helps the bear to move along the rough surface, this layer is renewed during hibernation (that is, a new one is growing), so the animal helps the process and accelerates it by biting off old areas.
