Here is a transcript of the video.
Narrator: No one likes to make their bed, let alone wash their sheets. Mostly single men. In a survey, 55% of single men between the ages of 18 and 25 said they only change their sheets four times a year. And to be clear, these are beds you wouldn’t want to sleep in.
You lose around 15 million skin cells every night, but they don’t build up in your sheets. Because something else is already there to swallow them up: dust mites. And the longer you wait between washes, the more food these critters will have and the more they will procreate and multiply. So if you don’t wash your sheets you will be sleeping with hundreds of thousands of arachnids.
Now, for the roughly 20 million Americans with dust allergies, the situation is getting worse. Dust mites and their feces produce proteins that cause red and itchy eyes, runny nose, and other cold-like symptoms in people with allergies. And dust mites, well, they’re actually not the only allergen in a dirty bed. If you never wash your pillow sheets, a fungal community can grow there as well. One study found that a typical pillow contains up to 16 different species of fungi and literally millions of fungal spores. And the most common of them, Aspergillus fumigatus, is potentially dangerous. In addition to allergic reactions, it can infect your lungs and other organs.
And it’s not just the mushrooms joining in the fun. You see, bacteria are also very fond of a good pillowcase or unwashed sheet. Another study found that unwashed pillowcases and sheets contained up to 39 times more bacteria than pet food bowls and several thousand times more bacteria than a toilet seat. Like Staphylococcus aureus, which in rare cases can be fatal.
Now, on a slightly less scary, if not scarier note, dirty sheets can also give you acne. Each night, the oil, lotion, and other cosmetics on your skin transfer to your sheets and build up over time until your bedding is finally a giant used makeup wipe. Then over the following nights all that gunk is transferred to your body, clogging your pores and voila, you get acne.
Fortunately, there is an easy way to avoid all of these problems: wash your sheets and wash them often. Experts recommend about once a week to use the hottest water possible. It will kill a lot of bacteria and mites, remove stains and remove oils.
Plus, as horrible as your bed can be, there is simply nothing better than slipping between crisp, clean sheets.
