If you canāt go a day without your morning coffee on holiday, weāve got bad news for you.
Instead of providing you with a taste of home, the kettle in your hotel room could be leaving you with a mouthful of someone elseās dirty underwear.
Thatās right, cleaning your grubby pants in hotel kettles is a thing, apparently.
The abominable habit shot onto our radars after a Twitter user asked others whether they had tried it. The man said heād heard about the practice from a friend.
Understandably, people on Twitter seemed to be as grossed out as us.
In case there was any doubt, Dr Heather Hendrickson, a senior lecturer in Molecular Biosciences at Massey University in Aukland, has confirmed that boiling your underwear in a kettle is a bad idea.
Speaking to Gizmodo, she explained that while boiling kills most germs, it doesnāt kill all microorganisms. This is because some bacteria form spores - such as clostidium botulinum spores - that are are resistant to heat below 120 degrees celsius.
āThese donāt cause sickness if they are consumed, but their presence in certain environments can encourage them to produce a toxin that can be deadly,ā she said.
Thankfully, boiling water contaminated with bacterial pathogens is likely to reduce any nastiness to low levels that are unlikely to seriously damage health.
But Dr Hendrickson still maintained that using a hotel kettle is āsuper, super, super, super grossā.
āWho knows how long that water, with nutrients that have been introduced and then sterilised, sits around in the kettle before someone else uses it?ā she said.
Well, thatās ruined hotel tea for all of us.
