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.

Yoga and Meditation May Lead to an Inflated Ego

If you’ve been exasperated for years by that one self-righteous, yoga-obsessed friend, take note: Regular yoga practitioners experience inflated egos after a session of yoga or meditation, according to a forthcoming study in the journal Psychological Science.

Researchers found that yoga and meditation both increase "self-enhancement," or the tendency for people to attach importance to their own actions. In the first phase of the two-part study, researchers in Germany and England measured self-enhancement by recruiting 93 yoga students and having them respond to questionnaires over the course of 15 weeks, Quartz reports. Each assessment was designed to measure three outcomes: superiority, communal narcissism, and self-esteem. In the second phase, the researchers asked 162 meditation students to answer the same questionnaires over four weeks.

Participants showed significantly higher self-enhancement in the hour just after their practices. After yoga or meditation, participants were more likely to say that statements like "I am the most helpful person I know" and "I have a very positive influence on others" describe them.

At its Hindu and Buddhist roots, yoga is focused on quieting the ego and conquering the self. The findings seem to support what some critics of Western-style yoga suspect—that the practice is no longer true to its South Asian heritage.

It might not be all bad, though. Self-enhancement tends to correlate with higher levels of subjective well-being, at least in the short term. People prone to self-enhancement report feeling happier than the average person. However, they’re also more likely to exhibit social behaviors (like bragging or condescending) that are detrimental in the long term.

So if you think your yoga-loving friends are a little holier than thou, you may be right. But it might be because their yoga class isn’t deflating their egos like yogis say it should.

The Honey Smacks In Your Pantry May Be Contaminated With Salmonella

Salmonella, a bacterial food-borne illness often associated with raw eggs and undercooked chicken, has been linked recently to a popular children's cereal. According to Snopes, the Centers for Disease Control and Prevention (CDC) is urging consumers to avoid Kellogg’s Honey Smacks, citing the brand as the likely cause of the Salmonella outbreak spreading across the U.S.

Since early March, 73 people in 31 states have contracted the virus. Salmonella clears up in most people on its own, but in some cases it can lead to hospitalization or even death. Twenty-four victims have been admitted to hospitals so far, with no reported deaths. Of the 39 patients who were questioned, 30 of them remembered eating cold cereal and 14 of them specifically cited Honey Smacks.

In response to the outbreak, the Kellogg Company has recalled its 15.3-ounce and 23-ounce boxes of Honey Smacks printed with any "best if used by" date between June 14, 2018 and June 14, 2019 (recalled boxes are labeled on the bottom with the UPC codes 3800039103 or 3800014810). The CDC recommends that you take even greater precautions by throwing out or returning any Honey Smacks you have at home, regardless of package size, "best by" date, or whether your family has eaten from the box previously without getting sick.

Symptoms of Salmonella include diarrhea, fever, headache, and abdominal pain, and usually appear 12 hours to three days after the contaminated food is ingested. If you or someone in your household is showing signs of the infection, ask a doctor about how to best treat it.
