Have you ever seen someone sleeping for a long time? Very quickly you will think of someone who is lazy. Although sometimes, don’t you also secretly wish that you could stretch your sleep-time for a few more hours, especially on a school day.
What if someone slept for months together? Now that is not laziness. Such kind of sleep is called hibernation. A lot of animals go into hibernation during the winter time when the climate is very cold and there is almost no food in the difficult weather. This is their body’s way of surviving the harsh winter. For example the ground squirrel goes into hibernation and its body temperature drops very low. So the body uses very little energy to survive. But they get up occasionally to eat a bite or go to the bathroom.
However Bears in the colder regions are a bit different from the squirrels or the bats. They really go into deep sleep for almost seven months. They realize that since there is no food they might as well nap 
. Once the weather is warmer with the coming of spring they start waking up.
So next time someone calls you lazy tell them about the bears
Facts
