We are African animals and we do not hibernate.
None of our relatives hibernate.
The only reason we are even alive this far north is because we have magic that protects us from the cold.
An English winter would kill me, if I was ever exposed to it without my magic.
Even if we had somehow managed to pick up a hibernation mechanism during our brief period as temperate climate animals, which is most unlikely because no human population has ever been caught hibernating, that would only apply to white people and black people get metabolic dysfunction too
It's probably not anything to do with hibernation.
While only some animals hibernate, torpor (a metabolic state of saving energy) apparently occurs in tropical animals, too.
What kind of parties do you get invited to where people talk about hibernation? Sounds like a fascinating crowd.
Worth remembering that there are metabolic effects of not having one's metabolism properly entrained with the seasons. No doubt many people in the Western world who have metabolic problems and also never go outside are stuck permanently in 'overwinter'ing mode.
