Hibernation of animals

Hibernation is an instinct for some animals to resist the cold in winter. They can hibernate for months without eating, not drinking, and not working and still not dying. The amazing thing is that mother bears often lay their babies at hibernation time.

For hibernation of animals, scientists have studied for centuries. They claim that under the skin of animals there is a thick layer of white fat, which can prevent body heat dissipation . There is also a layer of brown fat in the area around the shoulder and chest bone of the hibernating animal, like an electric carpet that produces heat 20 times faster than white fat. Moreover, the cooler the sky, the faster the heat is produced.

When the ambient temperature is low, sensory cells of hibernating animals transmit signals to the brain, stimulating sympathetic nerves of brown fat, making brown fat heat enough to ensure hibernation of animals at the point of being unable to die.

Black bears before hibernating for 1 month every day and night have up to 20 hours of eating, the amount of cumulative daily heat from 7000 increases to 20,000 calories, body weight increased by nearly 50kg. This means that in animals there are some auto-substances that lead them into hibernation.

To corroborate the above speculation, the scientists experimented on yellow mice. They took the blood of hibernating mice and injected them into the active vein, then put them into the room with a temperature of 7 degrees Celsius. Several days later, they all hibernated, which proved to be a sleeping guide natural east.

People took the blood of hibernating animals separately separated from serum and red blood cells, then injected with 2 groups of golden mice. soon after, they all hibernate. Again filter the serum to remove the filtered substance and the remaining substance, inject each thing into the golden rat and see the new filter only cause hibernation. Thereby, it is suggested that hibernation is a substance with very small molecules. The concern is that the serum of the sloth (marmota) causes hibernation for the golden rat to be most effective, regardless of whether it is winter or summer, it is possible to put a yellow rat into hibernation.

Finally, the scientists concluded: Hibernation is not only determined by narcotic substances, but also determined by the effects of narcotics and anti-sleepers . Animals reproduce narcotic substances throughout the year, but sleepers only produce in the spring and autumn, the sleeper causes enough to catalyze the animals to hibernate. By the spring, anti-sleepers are produced enough to inhibit sleep causing animals to wake up.
