There are countless reasons why the internet, with its vast amount of knowledge available, is a very helpful tool.

Even if there seems to be no end to the benefits it offers us on a daily basis, its ability to be a never-ending source of shared knowledge may be what makes it the greatest invention of the last few centuries.

There is no topic that you can’t read up on, no answer that’s beyond your reach if you know where to look. Mysteries that would have remained elusive in all the decades up to now can be solved quite literally with a few clicks of a mouse, a few stabs at a keyboard.

Over the years we’ve seen many old myths debunked online, just as we’ve seen life-hacks and helpful hints become common knowledge, whereas once they would have been wisdoms held by only a small few.

For instance, have you ever pondered why your underwear sometimes appears to have bleach stains on it? If so, you’re not alone, it seems, as ladies looking for solutions have asked the same question online.

And answers they found. As it turns out, said patches of coloring have absolutely nothing to do with your machine (as some have speculated).

Now, according to reports, the vag!na’s natural pH levels are what really produce these “bleach” spots.

Let us emphasize once more that there is no reason for concern regarding this before moving forward. Instead, it’s a good indicator if you find the previously stated spots on your underpants. As is common knowledge, a liquid or substance’s pH level indicates how acidic or alkaline it is. However, one useful tweet states:

“Now that everyone is aware, it’s completely normal to discover lighter patches in a woman’s underwear or knickers due to the acidic nature of the vag!na, with a pH range of 3.8-4.5. So, I suppose it’s time to abandon the notion of it being a result of poor hygiene. In fact, a healthy vag!na is one that can bleach the fabric.

According to Dr. Vanessa MacKay of the Royal College of Obstetricians and Gynecologists, the vagina has a natural secretory system that allows it to clean itself. It is protected by the good bacteria that it contains.

According to the National Institutes of Health, the pH of the vagina typically fluctuates from 3.8 to 5.0, which means that it is rather acidic compared to the normally neutral pH level of 7.

Dr. MacKay continues, “Disturbing the natural balance can lead to infections, but it’s perfectly normal and healthy for women to have clear or white discharge from their vag!na.”
