Air is a good insulator
As papers are wrapped air is trapped between them this and the paper are both insulators of heat thus preventing body heat from escaping

A beggar wraps himself with a few layers of newspapers on a cold winter night to keep himself warm. This is because paper is a good thermal insulator and keeps the objects wrapped using it quite warm. Moreover, it is one of the easiest and cheapest insulating material to keep oneself warm.
