Concept:

In the winter season, the body temperature is more than the atmosphere and as a result, radiation energy loss takes place.

Our body emits radiations in the infrared range and white color absorbs the infrared radiations.

Thus, fewer radiations are emitted than are absorbed and as a result, it keeps us warm.
