This was an interesting article, though it looks like more testing needs to be done on the idea. I sometimes joke that I wish people hibernated because I don’t want to have to bother with all the snow removal that has to be done in the northeast during winter.
When I started reading this, I wondered why hibernation would be possible for some humans but not for others such as Inuits who live in very harsh conditions for most of the year, but that was addressed eventually:
The answer, say Arsuaga and Bartsiokas, is that fatty fish and reindeer fat provide Inuit and Sami people with food during winter and so preclude the need for them to hibernate. In contrast, the area around the Sima site half a million years ago would not have provided anything like enough food. As they state: “The aridification of Iberia then could not have provided enough fat-rich food for the people of Sima during the harsh winter - making them resort to cave hibernation.”
