More blankets don't help the moment you get out of bed in the morning. The apartment was unheated for much of the winter during my teenage years, so I usually wore two pairs of thick woolen socks and thick woolen PJs (along with a thick duvet and several blankets) so I wouldn't freeze to death the moment I got out of bed. The period between rushing out of bed and into an 8 ply woolen bathrobe was still painful though.
