For the same reason that orgasms are better if you’re wearing socks.
This is the first I’m hearing on the matter/association between socks and orgasms 🧦🍆💦
I read it in some medical journal many years ago, but I already knew it from experience.
Sure…
Conversely, I like to have my feet poke out from under my duvet.
Same, my feet are always warm or hot, I walk around all winter on hardwood floors with no socks.
I rarely wear shoes when not outside and will be bare foot as much as possible (so I have Hobbit feet). I do have Raynaud’s though, so have made to wrap up a bit warmer these days.
This is due to vasodilation.
“Vasodilation occurs in superficial blood vessels of warm-blooded animals when their ambient environment is hot; this process diverts the flow of heated blood to the skin of the animal, where heat can be more easily released to the environment. The opposite physiological process is vasoconstriction. These processes are naturally modulated by local paracrine agents from endothelial cells (e.g., nitric oxide, bradykinin, potassium ions, and adenosine), and by the autonomic nervous system and the adrenal glands, both of which secrete catecholamines, such as norepinephrine and epinephrine, respectively.[6][7]”
It’s the opposite of vasoconstriction, which occurs when you’re cold and your extremities have less blood flow to prioritize the warmth of your core organs.
