If you suffer leg cramps as you sleep, you'll love this next wives' tale: Put a bar of soap in your bed to relieve nighttime leg cramps. This is definitely one of the more controversial wives' tales, and the truth is that there is little more than anecdotal evidence to support the hypothesis. However, the remedy appears to be effective, and many people report it working. It may be little more than a placebo effect, but placebos have been proven effective in many cases. [caption id="" align="aligncenter" width="565"] Source: livecleanbestrong.com[/caption] Some people believe that there is some unknown molecule in the water-swollen gel that is your bar of soap, and that this molecule helps to alleviate cramps. After a time, there are no more of these molecules emitted by the soap, so the bar of soap must be changed. Research has found that most bars of soap must be swapped out after 6 months in order for the remedy to continue being effective. Why does this remedy work? No one knows, but research has discovered that it DOES work.
