The Internet: A Well of Shared Knowledge

Though there seems to be no end to the advantages it brings to modern life, the internet’s greatest gift is perhaps its boundless well of shared knowledge. There is virtually no topic beyond reach—no mystery unsolved if you know where to look. Questions that might once have lingered unanswered for decades can now be resolved with a few keystrokes.

Over time, countless myths have been debunked online, while life hacks and practical wisdoms—once known to only a few—have become common knowledge. Take, for example, the curious question many women have asked online: why does underwear sometimes appear to have bleach-like stains?

According to Dr. Vanessa MacKay of the Royal College of Obstetricians and Gynaecologists, the vagina is self-cleaning, using natural secretions that contain protective bacteria. With a slightly acidic pH of 3.8 to 5.0—compared to the neutral 7—it’s normal for these secretions to cause mild fabric discoloration over time. This is a natural, healthy process, not a sign of illness or poor hygiene.

However, true bleach stains can also result from external causes, such as contact with bleach-based detergents, chemical reactions between fabrics and bodily fluids, or residue from personal care products.

To prevent such discoloration, experts recommend using color-safe detergents, washing whites and colors separately, handling bleach carefully, and following garment care labels.

In the end, it’s another reminder of how the internet transforms curiosity into clarity—offering practical knowledge with just a few clicks.
