Is it safe to wipe after a wee with a snotty tissue?

Dear Aunt Vadge,

Sometimes I blow my nose into the toilet paper, then – to be environmentally friendly – use the same paper to wipe after weeing. I don’t wipe the snot onto myself; I use the other side. Is this safe?

Yours sincerely,

Dear J,

I love the eco intention, so a measured answer rather than a horrified one. Most of the time you’re probably fine, because you’re using the clean side and not putting snot directly onto your vulva.

The small catch is that your nose is a debris-catcher – it traps bacteria and gunk from the air, which then end up in your tissue – and while those respiratory germs aren’t usually the ones that thrive in your vagina, your urethra sits right there. And it’s not impossible to ferry a stray microbe somewhere it could cause a UTI or irritation.

Germs are opportunists. So my verdict: a couple of dry boogers wrapped well into the far side, fine; but when you’ve got a cold or flu, or there’s stringy snot that won’t stay put, reach for fresh paper and flush the snotty bit, because that’s exactly when the bug load is highest and the small risk isn’t worth it.

And on the green front, this is a tiny saving. And we live somewhere with excellent wastewater treatment – you’ll do far more for the planet by, say, skipping bottled water than by squeezing two uses out of one tissue. Choose your battles; your vulva will thank you.

Best,
Aunt Vadge
