the body's polite reminder that it would prefer to be elsewhere immediately
means Having a low temperature, or feeling a lack of warmth, whether in the air, an object, or someone's demeanor.
from From Old English 'cald' or 'ceald,' tracing back to Proto-Germanic '*kaldaz' — the same chilly root that gives German 'kalt' and the 'cold' in 'cold shoulder.' It's a cousin of Latin 'gelu' (frost) and 'gelidus,' so the same deep family that froze Old Europe also gave us 'gel,' 'gelato,' and 'congeal.' The word has meant 'low in temperature' since before English was written down, and the figurative chill — a cold welcome, cold comfort — has been hanging around almost as long.
