Women who use a vaginal douche could be at a higher risk of exposure to potentially dangerous chemicals, according to a University of Michigan study that looked at the correlation between the use of female hygiene products and the levels of volatile organic compounds in women’s blood.
The study found a significant association between vaginal douching and higher blood concentrations of 1,4-dichlorobenzene, a volatile organic compound.
According to the study, women who used a vaginal douche two or more times per month had concentrations 81% higher than those that never used. Women who used douches occasionally (once a month) had 18% higher concentrations of the chemical.
VOCs are chemicals that are used in a wide-range of products including deodorants, nail polish and paints. Some of these chemicals have been associated with respiratory symptoms, cancers and neurological disorders, as well as adverse effects in reproductive systems. [emphasis mine]
I assume this refers to packaged douche products, not to mixing vinegar and water at home, or baking soda and water.
