Noticing “bleach” patches on underwear has puzzled many people, but the explanation is quite simple and related to the body’s natural processes.
These discolorations are due to the acidic nature of the vagina, which has a pH range of 3.8 to 4.5. This acidity is a healthy sign, as it plays a crucial role in preventing infections by inhibiting the growth of harmful bacteria.
Dr. Vanessa MacKay from the Royal College of Obstetricians and Gynecologists explains that the vagina’s self-cleaning ability through its secretions, which can cause these light patches on fabric, is a normal function aided by beneficial bacteria. It’s a misconception that these patches are due to poor hygiene.
In fact, these patches indicate a well-balanced vaginal environment. Understanding this helps demystify the body’s natural processes and highlights the importance of maintaining the natural pH balance for overall vaginal health.
