Especially at this time of year. I write in the evenings in an unheated room. I don't tend to notice how cold I've gotten until I stop and stand up, toes aching with cold, fingers stiff, shivers wracking my body. Then I plunge into the hot bath and re-discover circulation.
It makes climbing into the cold bed better too. Rather than curling into a ball and waiting for the sheets to warm around me for several minutes, I can just lie down and feel the heat radiating off me into the bedclothes. I'm sure I fall asleep much faster.
Baths also give me time to read. I lie there, cup of tea within easy reach, and read books. No e-reader for me, folks! I do occasionally fall asleep in there and baptize a library book, which is not so great, but I have a pretty good method of drying them out again without getting that terrible swollen book thing going on.
I often have my best writing ideas in the bath. I'll realize I've been staring at a page in my book for an aeon, not absorbing a word, while whole sequences of scenes and characters run riot in my head. The beginning of Taillights came to me in the bath. A huge number of short stories too. And my new WIP, The Boyfriend Plague.
Do you have an everyday activity which inspires your writing? And what kind of bath products do you like best?
