Does our body expect to experience seasons?

Someone once told me that it is normal for us to put on weight in late Autumn, to help us get through the winter. It is also normal for us to be thinner in Spring.
I hate using electric blankets or air conditioners. I want to feel the weather.

I think, that if your body is made to feel cold or in want in the summer or fall, you will change your sleep habits and look to find and store food. I live the in the weirdest climate after not living it in… and I can attest, it screws you up 100%. No doubt. Sleep, eat, rest…. the stupid sun screws it all up, by either up too much or being gone too much. I used to have a very good, steady, healthy circadian rhythm, but moving to the asshole and beyond has sucked me of any sense or reason. I recently feel the territorial need to barricade a section of my physical property off because the neighbours were using it and I didn’t want them that close. How weird is that?? Seemed very reasonable.

I don’t think our bodies expect to experience seasons, I just think our bodies adjust to the seasons as well as it can.

I once argued on a Q that humans became whiter as they migrated to colder climates. Paler skin, blue eyes, blond hair. I had just been in Alaska and when I was in glacier bay there is mostly ice and water and the colors around you are white and blue. Literally some of the ice is blue-ish. Being tan in the summer we blend in with the browner tree tree trunks in the forest. I really see it as a camouflage. But, almost everyone talked about how pale skin absorbs vitamin D better. I do see the logic in that, and I always thought that myself, but I can tell you for me, I am very pale, and can’t be out in the sun for more than 20 minutes without burning. My avoidance of the sun has left me vitamin D dificient, so that was not a perfect system evolution gave me. My husband has olive skin and his vitamin D is always good, but he gets more sun than I do. Anyway, I was also thinking how some Native Americans have more of a red tan, and maybe they lived where the lands were red clay? But, enough of this tangent.

Plenty of people live close to the equator where there is basically almost no change of seasons. If what you suggest is true, they would have all sorts of problems, but they don’t. My happiest time in my life was living in FL with minimal season change. Being warm all the time suited me very well. Having more days of sunlight made me very happy.

@JLeslie I like your reasoning!

I’m much more energetic in the summer than the winter. Something about cold and dark make me want to hibernate. It was unbearable when I lived in Eastern Europe but I feel much better in South America energy-wise.
