I had chemo and the center I went to always had blankets for anyone who wanted one. It wasn't a fancy clinic either. No private rooms, tv and such but a wonderful staff, camaraderie among those of us getting treatment. Many, including me, brought our own blankets to use. Some friends made me a quilt which I took to curl up with. I was there each time for about 4 hours. Many were there longer so in addition to the chill factor there is comfort in having something to cuddle up with.
