UV Photos Show the Areas We Miss When Applying Sunscreen

Sunscreen only works if you're actually wearing it. And it's too easy to go through the motions of putting on sunscreen while still leaving large amounts of skin unprotected. Even if you're applying the recommended shot glass of sunscreen before you head out into the world, parts of your skin may still be exposed to harmful rays. Just check out these UV images taken by researchers at the University of Liverpool, spotted by the UK's Metro.

The black-and-white images were taken with a UV camera so that any part of the skin covered by UV-blocking sunscreen would appear dark. Skin without sunscreen on it, by contrast, remains visible. The 57 volunteers in the study—which was recently presented at the British Association of Dermatologists' Annual Conference—were instructed to apply sunscreen to their face as usual.

Some volunteers were more thorough than others, but as a whole, the group ended up missing a median of 9.5 percent of their faces. Men with beards tended to miss a lot of their faces, you might notice in the photos, and people seemed to have trouble with covering the full area around their mouth. However, the main problems occurred around the eyes. Many people missed their eyelids, and more than three-quarters of the group missed the medial canthal region, or the area between the bridge of the nose and the inner corner of the eye.

The finding is significant because the area around the eyes are particularly susceptible to skin cancer. According to the abstract presented at the conference, 5 to 10 percent of skin cancers occur on the eyelids.

Knowing this doesn't necessarily help, though. When the participants were brought back for a second visit, the researchers gave them new instructions that included data on cancer risks for eyelids, the results barely changed. People put slightly more sunscreen on around their eyelids (they missed a median 7.7 percent instead of 13.5 percent of the area) but almost everyone still missed their medial canthal area.

It's not a surprising finding, considering the fact that no one wants to get sunscreen in their eyes. Sunscreen manufacturers recommend that you keep it out of your eyes, and if it does run, you'll end up in tears. So it's not particularly useful to tell people they should be coating their eyelids in Coppertone.

To keep your face super smooth and reduce your likelihood of sun damage, then, the message is clear. Better get some shades, unless you've got a UV-blocking eyeshadow on hand. Better yet, get yourself a hat, too.

7 Quick Tips for Disinfecting Your Home the Smart Way

With many people spending more time—or virtually all of their time—indoors, it’s natural for thoughts to turn to how to best clean surfaces that might help minimize the risk of spreading illness. Although researchers believe respiratory droplets are the primary way coronavirus is transmitted, preliminary data, which is not yet peer-reviewed, suggests the virus may remain on some surfaces for hours or days.

While scrubbing isn't a complex process, there are nonetheless some areas of your home you might be neglecting. Here’s how to best approach a household scrub, as well as identify and disinfect some common germ hot spots.

1. Pay attention to high-touch surfaces and clean them frequently.

High-touch surfaces are exactly what they sound like: Areas in the home that get handled and touched regularly. Think doorknobs, light switches, appliance handles, toilet handles, faucets, and remotes. And don’t forget laptops, keyboards, desks, and phones.

2. Don't just do a quick wipe down. Get the entire surface.

Taking a disinfecting wipe to the keyhole of a doorknob isn’t going to do you much good—it's important to really scrub all high-touch surfaces. Make sure you get every available surface area, including the plate behind the knob where fingers and hands often brush against it. When cleaning remotes, make sure you don't just scrub the buttons, but the space between them as well.

3. You can use soap and water.

While products claiming to kill 99.9 percent of germs are best in this scenario, there's another option if you're having a hard time tracking down those supplies—simply mix some dish soap in water. It won’t kill organisms, but it can remove them from the surface. (And while soap and water can work for high-touch surfaces throughout the home, you shouldn't use the solution on electronics like your remote or keyboard.)

If you’re looking to kill germs, diluted bleach (four teaspoons to one quart of water) and 70 percent alcohol solutions work well. But it's important to note that bleach and other cleaners can harm certain surfaces. So be sure to do your research and make sure the product you're using won't cause any damage before you start scrubbing.

4. Take laundry precautions.

If you’re trying to be extra-vigilant about the spread of germs in the house, you should consider washing clothes at the highest possible temperature and disinfecting laundry bins. It’s also advisable to use disposable laundry bags.

5. Remove your shoes before entering the house.

This step is more preventative, but it’s a simple way to keep from tracking in contaminants. Remove your shoes before going inside and leave them near the door. It's also a good idea to clean floor surfaces with disinfecting mop cloths, but be sure anything you use is safe for the finished surface. Cleaners like bleach can discolor certain materials.

6. Don't forget to clean your car.

Even people vigilant about cleaning their home can neglect their car interior. Since you’re constantly touching virtually every surface, be sure to wipe everything down regularly, including the steering wheel and door handles. If you have a leather interior, there are auto wipes available for those surfaces. And before you go wipe down any touchscreens, be sure to check your owner’s manual to see if they require any special microfiber cloth.

7. Give your debit cards a wipe.

It’s a good idea to disinfect credit or debit cards that follow you around on shopping excursions. As with all high-touch objects, be sure to wipe them down every day.

The World Health Organization Is Releasing a COVID-19 App to Combat Coronavirus Misinformation

As is the case with most crises, the novel coronavirus has become a breeding ground for misinformation. Because the disease is so new, there are a lot of unanswered questions surrounding it, but that hasn't stopped people from claiming to know how to treat, prevent, and detect COVID-19. In an effort to separate fact from fiction, the World Health Organization (WHO) is launching an app dedicated to sharing what we know and don't know about the virus, 9to5Google reports.

Named WHO MyHealth, the new app is a collaboration between former Google and Microsoft employees, WHO advisors and ambassadors, and other tech and health experts. Users will be able to compare their symptoms with those linked to COVID-19 and receive public health updates specific to their location. As of now, there are plans to invite people who have been either been diagnosed with or exposed to COVID-19 to share their phone's location history to give experts a better idea of how the virus spreads.

WHO MyHealth, which is currently being built as open source, is set to roll out for Android and iOS on Monday, March 30. If you have questions about COVID-19 you need answered immediately, you can also access accurate and up-to-date information through the WHO's chatbot.

Any information regarding novel coronavirus should be met with skepticism when it can't be traced back to organizations like the WHO or the CDC—especially when it comes to supposed cures. No specific medication has been proven to treat or prevent COVID-19, so you shouldn't take advice from anyone claiming otherwise.
