Bathroom Hand Dryers Might Be Blasting Us With Poo Particles

Using a public restroom can be a stressful experience. People inevitably shake the flimsy stall doors to check for occupancy. Soap can be missing and gastrointestinal noises can be heard. Now, a new study has found that the perils of public voiding may not end at the sink. The wall-mounted hand dryers—often believed to be a sanitary solution—could be blasting fecal bacteria right back on your hands.

Published in Applied and Environmental Microbiology, the report looked at 36 bathrooms at the University of Connecticut School of Medicine. Samples of bacterial colonies were taken on plates. A typical bathroom air sample averaged less than one colony, while plates positioned underneath a hand dryer for 30 seconds averaged 18 to 60 colonies per plate.

Researchers aren't yet sure whether the dryers are actually harboring bacteria or simply sucking it up and then blowing a concentrated amount back out: Swabs of dryer nozzles had only minimal bacteria levels. Researchers found that installing a HEPA filter in the dryers dramatically reduced their bacterial load.

Bacteria in a public bathroom are likely coming from nearby toilets, which don't have lids and can release fecal particles when flushed. So what do you do if you don't want weaponized poo on your freshly washed hands? Avoid the dryer and stick with paper towels. But for relatively healthy people who aren't immunocompromised, a few blasts of contaminated air probably won't harm you.

Looking to Downsize? You Can Buy a 5-Room DIY Cabin on Amazon for Less Than $33,000

If you’ve already mastered DIY houses for birds and dogs, maybe it’s time you built one for yourself.

As Simplemost reports, there are a number of house kits that you can order on Amazon, and the Allwood Avalon Cabin Kit is one of the quaintest—and, at $32,990, most affordable—options. The 540-square-foot structure has enough space for a kitchen, a bathroom, a bedroom, and a sitting room—and there’s an additional 218-square-foot loft with the potential to be the coziest reading nook of all time.

The construction process might not be a great idea for someone who’s never picked up a hammer, but you don’t need an architectural degree to tackle it. Step-by-step instructions and all materials are included, so it’s a little like a high-level IKEA project. According to the Amazon listing, it takes two adults about a week to complete. Since the Nordic wood walls are reinforced with steel rods, the house can withstand winds up to 120 mph, and you can pay an extra $1000 to upgrade from double-glass windows and doors to triple-glass for added fortification.

Though everything you need for the shell of the house comes in the kit, you will need to purchase whatever goes inside it: toilet, shower, sink, stove, insulation, and all other furnishings. You can also customize the blueprint to fit your own plans for the space; maybe, for example, you’re going to use the house as a small event venue, and you’d rather have two or three large, airy rooms and no kitchen or bedroom.

The U.S. Postal Service Is Struggling—Buying Stamps Can Help

Throughout the coronavirus pandemic, businesses have drastically reduced the number of advertisements and other marketing materials they’re sending to consumers—and since a considerable chunk of the U.S. Postal Service’s (USPS) revenue comes from those large mailings, the ongoing crisis has put the organization in a tough spot.

The importance of keeping the USPS afloat goes beyond simply wanting to preserve something that’s been around since the dawn of U.S. history. As Lifehacker explains, the institution delivers mail to every single household in the nation—be it by truck, boat, or even mule—which makes it a critical method of circulating necessary documents like paychecks and voting ballots. Without the USPS, it would be difficult to reach rural residents who might not have consistent phone or internet service.

So, how can we help? The USPS doesn’t get any taxpayer funds, relying instead on the sale of stamps and various shipping supplies. In other words, the best way to put money into the pockets of our postal guardians is to stock up on stamps.

There are dozens of different designs listed on USPS’s online store, which makes this charitable endeavor an especially fun one. You can, for example, decorate your envelope with Sally Ride, Scooby-Doo, or celebrated broadcast journalist Gwen Ifill. There are plenty of fruits and flowers to choose from, too, and even a lovely illustration of Walt Whitman, complete with a very thick mustache and a very piercing gaze. And we’d be remiss not to mention the existence of this mail carrier dog costume, which only costs $18.

If you’d like to go the extra mile, you can also sign a petition to save the USPS by texting “USPS” to the number 50409. A chat program called Resistbot will walk you through the steps to add your name, and it’ll even send an automated message to your senators, letting them know you’ve signed the petition and support the continued operation of the USPS. You will have to enter your name, email address, and residential address, but the whole process takes about two minutes.
