They've been putting Twisters where one should never put Twisters.

Oh boy. With temperatures soaring to nearly 40 degrees in London today, things have really been heating up. And by that, we mean Londoners have been resorting to extreme measures to cool off - most of them perfectly reasonable.

Air con? Good idea. A cold shower? Sure. Putting a popsicle inside your vagina? Sorry - what?

Tips to beat the summer heat Time to ditch the aircon and try one of these tips to keep you cool this summer!

Yes, you read that right.

Some women have apparently been putting Twisters and Calippos where one should never put Twisters and Calippos.

Decided to put an ice lolly up my vagina to help me cool down. It was FAB. — ☆⚓Mįśš~Fïtż⚓☆ (@Wasrayray) June 19, 2013

But the problem - aside from the obvious - is that inserting a frozen object into your vagina can cause a whole swarm of issues, from burning to itching to just general pain.

"The vagina is composed of very delicate and sensitive skin," Dr Sarah Welsh, the co-founder of HANX, a condom brand, tells UK website Metro. "Hence, things that may seem innocent to other areas of the body, if they come in contact with the vagina, can cause infections, irritations and damage."

can you believe i just witnessed a video of a woman putting an ice lolly into a woman’s vagina.... an iCE LOLLY — charlotte (@cabbbbello) July 29, 2018

Of all the things that should never go near a vagina, she continues, popsicles are "up there", because the ice can stick to the vaginal wall and cause "real trauma and damage", not to mention the disruption to the bacteria, which could cause infections (swapping to a sugar-free option will not help, Dr Welsh qualifies).

Worse still, the popsicle could actually break off inside you and would be less then comfortable, one would imagine.

Instead, experts are recommending women wear loose cotton underwear, perhaps take a cold shower or even run a cold ice cube over (the outside of) your body.

Or, as gynaecologist Dr Shree Datta so delicately puts it: "leave the vagina out of it".
