This has caused many problems to be asked for decades. Now, a new research may have demonstrated why the polar bears did not freeze.

First discovery: infrared cameras and cold fur

Discover Wildlife reports that this discovery began when Professor Bodil Holst of Bergen University could not see the polar bears of infrared cameras while watching a television program. Realizing that their furs were extremely cold, the professor began to question why they were not freezing. Then, Julian Carolan, a doctoral student from Trinity College Dublin, set up a team to investigate the reason why polar bears survived in calf environments.

Sebumun Secret: Natural Skin Oil

According to the findings published in Science Advances, the answer to this situation lies in the natural skin oil, which is secreted from the glands under the furs of polar bears. This oily coating contains a water -repellent mixture, cholesterol, diasilglycerol and fatty acid. This natural oil prevents freezing in their bodies by allowing water to slide rapidly from the fur. According to the researchers, this situation is very important in terms of survival, as it will make it difficult for the bears to remain hot by imprisoning the cold of the frozen fur and reducing the insulation.

Privacy and Role of Natural Fat in Hunting

This natural oil helps them to remain dry as well as to remain hidden. One of the basic nutrient sources of polar bears is seals and they need to follow these animals without noticing. The natural oil secreted by their bodies allows the polar bears to move silently on the ice to follow the seals.

Apparently, local polar communities have long known the unique features of the polar bear fur. Researchers found several historical recordings that hunters used polar bear fur in hunting vehicles. Now, scientists are investigating whether there are similar characteristics in the furs of other bear species, such as brown bears.
