The key is in your neurons.
Have you heard about hibernation? Do you know how it works?
During hibernation the animals remain immobile, lower their body temperature and respiratory rate. This is achieved, among other things, thanks to the brain.
American researchers studied the brain of the ground squirrel, also known as thirteen stripes, and the Syrian or golden hamster, do you want to know what they discovered?
They found that the neurons of both animals have evolved so they perceive less cold than other rodents that do not hibernate.
Their neurons are less able to detect temperatures below 20 degrees than other animals.
Imagine squirrels can hibernate for up to eight months! and the hamsters a few more weeks!
