This month in the journal Sleep Science, Brazilian researchers speculate that masturbation may calm restless leg syndrome. Previous studies have shown that an imbalance of dopamine may be a contributing factor. Drugs that increase dopamine have been shown to reduce RLS symptoms, but an orgasm, which provides a natural dose of dopamine, may help too. The researchers only mention possible benefits for men, but if any of you ladies suffer from RLS, there's no harm in performing a one-woman scientific study.
