Perhaps counter-intuitively, I have found that applying more layers to my core rather than to my fingers/hands tends to keep my fingers warmer.

Of course, this only works if blood can circulate heat from your core to your extremities. Try throwing on a vest and, when coding, make sure your elbows are not bent and your writs are not resting on a pad in such a way as to obstruct blood flow.

Good luck!

This works for me. It's more of an issue when I'm playing music than coding. So I put on socks, slippers, a nice sweater, or maybe a hoodie, even a hat.

From what I've read, when the core gets colder, the body withdraws blood from the extremities.

I tried googling for this but got mixed results. Shouldn't the wrists be touching/resting on the desk (the piece of desk between the keyboard and me) or are they suppose to float?

[cauterized]

They're supposed to float. It's much better ergonomically.

Look for images/videos of professional pianists -- ideal wrist ergonomics for typing are very similar to those for playing piano.

Specifically, your wrists should be loose and relaxed, so that your hands would hang down loosely if the fingers weren't resting on anything. My piano teacher used to spend a few minutes at the beginning of each lesson shaking my forearms until the wrists loosened enough!

Also if you are "hair-challenged" on your head like me, wearing a hat helps as well.
