Sleep hygiene has garnered a lot of attention in medical circles, as individuals spend a third of their life in bed. It is believed sleeping naked could improve the quality of rest for sleep-deprived individuals, as well as improve the skin’s health and appearance. The condition of your bedding, however, is just as important for your health. While many studies have purported the benefits of sleeping naked, one American doctor suggests germ-laden gas could dirty your bed sheets.
“That same study showed that your tighty-whities will catch all of these particles for the sake of your bed partner, please sleep with your underwear one.
The video, which was shared by the popular plastic surgeon, has been viewed a whopping 8.2 million times on YouTube.
Dubbed America’s Holistic Plastic Surgeon, Dr Youn added: “For women – if your gyno tells you to sleep without underwear, then listen to them.
“For guys – put your tighty whities on before bed!
“And change your sheets regularly you disgusting animal!”
While the medic did not specify which study he was referring to, a BMJ study in 2001 set out to determine whether flatulence was germ-laden or malodorous.
Speaking of the study, the paper’s author Doctor Karl Kruszelnicki said: “It all started with an enquiry from a nurse, she wanted to know whether she was contaminating the operating theatre she worked in by quietly farting in the sterile environments during operations.
The researcher conducted an experiment by asking a colleague to break wind directly onto two Petri dishes from a distance of five centimetres, once fully clothed, when with his trousers on.
Overnight, the Petri dish sprouted visible lumps of two types of bacteria that usually reside in the gut or on the skin.
Doctor Kruszelnicki noted that the wind that had passed through the clothing had not caused bacteria to sprout, suggesting that clothing acts as a filter.
Doctor Kruszelnicki added: “Our deduction is that the enteric zone in the second Petri dish was caused by the flatus itself.
“It seems that flatus can cause infection if the emitter is naked, but not if he or she is clothed.
“But the results of the experiment should not be considered alarming, because neither type of bacterium is harmful. In fact, they’re similar to the ‘friendly’ bacteria found in yogurt.”
Dead skin cells, sweat, saliva can also cause germs to fester on your sheets, with lab tests showing pillowcases can harbour 17,000 times more colonies of bacteria than samples taken from a toilet.
Furthermore, studies have shown that the human body sheds more than 500 million skin cells daily, which can pile up on sheets during sleep.
This can attract dust mites, which discard droppings which can trigger allergies, asthma and cause excess to flare up.
