The first house where I lived in Wales did not have central heat, or even automatic hot water. The UK in the winter can be incredibly damp and cold, and you get chilled to the bone. Aside from being almost fully clothed when I went to bed, I found that the best solution to keeping warm was a hot water bottle. I would stick it at the foot of the bed as I was getting ready for bed, and by the time I jumped in, the area where my feet were was all nice and toasty. As I fell asleep, I’d move the bottle around so it would warm my back and then my front. I haven’t had a hot water bottle since then, but recently bought one because my back was hurting. I remembered what a wonderful simple little item this is, and have been using it for a few weeks. I find that I can turn the heat down lower when I go to bed and stick my bottle at the bottom of the bed like I did in Wales. I played around with making a cover for it using an old cashmere sweater. Now it will be doubly nice! You can find the old-fashioned red hot water bottles at any drugstore.
