ELI5: I'm in my room, at room temperature, wearing nothing but socks. Why the fuck are my feet so cold?

In general, your feet are the last place which your body warms up. If your internal organs and your brain are cold (which is likely, since those parts of your body were naked) then blood will be diverted from the extremities such as hands and feet to keep these parts warm. Even wearing socks won't keep your feet warm if there's reduced blood flow to your feet.

Having said that, if you are in any way worried about this, please see a doctor who will be able to check whether your blood circulation is normal.
