Why can't humans hibernate?

HUMANS; HIBERNATION?

   Yes, recently I've been thinking why can't we humans hibernate ...?

We're way ahead in thinking and conscience compared to other animals which hibernate. So can we develop any technology that can allow us to hibernate?

Need for hibernation

   Why do animals hibernate?  Because they can't survive the harsh weather particularly cold weather. Now coming to humans, as Space colonization is the next big step in the evolution of life, we need to travel to the other planets. For a stance, it takes 8 months to travel to the Mars with the presently available technology. And there is no other planet in our Solar system on which life can exist. So if we've to travel to the neighboring galaxies at the speed of light, it would take years. Clearly we can't carry all the food required, so hibernation is the next alternative.

What hinders us from hibernation?

   To understand this we need to understand why animals hibernate. The most obvious reason is to avoid cold. Hibernation is extended period of energy-saving torpor. During hibernation the rate of heart beat, respiration and metabolism comes down to a minimum level. As a result body temperature decreases. Hibernation is frequent in northern hemisphere than in southern hemisphere, as the lands in the southern hemisphere are closer to equator, the winter is milder. Majority of the animals hibernate during winter but a few hibernate in summer too, it is called Aestivation.
   A closer attention on the smaller animals which hibernate tells us a new thing. These smaller
animals like squirrels, skunks, hamsters retreat to a burrow underground and sleep not only to escape the winter but also to protect their life from the animals superior in the food chain.
   While the bigger animals, apex predators, hibernate solely to the escape the perilous winters.
   And this isn't the only difference between these inferior and superior animals; The way they manage to keep their biological operations, like respiration, metabolism, going on. Squirrels, and other similar animals, become busy throughout fall caching food. They gain fat and body mass, these layers of fat serve two purposes. The fat layers act like blankets and are energy reserves too.
   Bears, similar animals, have a better plan for the winter. They mate before the arrival of winter and they too gain body mass tremendously. They breed during winter i.e during hibernation.
        But human body is not suitably designed for storing enough fat for the entire winter. Moreover too much fat obstructs heart functioning.
