Cold

I am really cold right now. My fingers are turning blue and my nose feels frigid.

1. It is cold right now.
2. I need to eat and my metabolism is slowing down.

How can I tell the difference between the two? I don't really feel hungry, but at the same time, other people nearby aren't cold. I need to find some sort of work mittens that will warm my hands but allow me to continue to type in order to work.

I don't really consider this a major problem or issue (on par with starving plague-ridden children, global poverty, military-industrial complex, etc.), but when you're cold, you're cold. You feel me?
