I read many years ago of a folk remedy--you put a bar of soap (unwrapped) under your bottom sheet probably somewhere around your knees. No one knows why this works (when it does). Here's some info off the net: Supposedly gives off magnesium. Not every brand does the trick (folks who try this say Dial and Dove don't work); Dr. Oz recommends soap containing lavender. One site re this says, "One possible explanation for the soap effect is the fragrance. A chemist suggested to us that the most popular soaps all seem to have the fragrant compound limonene in their scent.... We suspect that transient receptor potential (TRP) channels are involved. (Limonene activates TRP A1.)"--https://www.peoplespharmacy.com/2017/11/27/why-put-soap-under-your-bottom-sheet/
