Douching
The practice of douching is surprisingly popular considering how many experts insist on its inefficiency. Although you may feel like douching cleans those body areas better than you ever could, the long-term results can be devastating.
According to Wendie A. Howland, principal of Howland Health Consulting, douching can seriously alter the pH of your skin. While it washes away that nasty bacteria, it also eliminates the good bacteria that keep your skin healthy, thus increasing your risk of infections.
Furthermore, a study published by Environmental Health showed that products designed for douching can alter hormone production. Over time, this imbalance might increase your risk of reproductive problems and chronic disease.
