Dermatologist Lindsey Zubritsky has a warning for everyone.

Remember when you were a kid learning how to take a bath and your mom said, “Don’t forget to wash behind your ears!” According to a viral TikTok video by dermatologist Lindsey Zubritsky (@Dermguru on TikTok), your mother was right.

In a post with over 3.3 million views, Zubritsky reveals the places you “absolutely need to be washing more often than you are.” They are behind the ears, beneath the fingernails and in the belly button. Zubritsky says that failure to keep those areas clean can result in some severe health problems that can be life-threatening.

First, let’s take a look behind the ear.

If you put your finger behind your ear and “notice an odor to it or you feel something you should be washing it more,” Zubritsky says. Dandruff, sebum, other hair, and materials from the hair and head can build up behind the ear, leading to dermatitis.

Next, let’s do a little navel-gazing.

Zubritsky says the belly button is a common area to collect sweat, debris and dirt buildup. According to the dermatologist, some extremely gross things can happen if you don’t clean there often enough. After watching this video, you will never forget to clean your belly button again.

“In fact, if you’re not cleaning it enough, you’ll have so much debris and dirt in there that you’ll develop a navel stone that looks like this,” she said as she shared a photo of a black stone protruding from someone’s belly button. The stone-like object is known as an omphalith and it may require surgical removal.

Finally, take a look beneath your nails.

“When you’re showering, you really need to get under those nails with a scrub brush to get rid of the dirt, debris and buildup,” she explained. Failure to keep your nails clean can lead to infections and pinworms.

Zubritsky concludes the video with a serious warning. If you don’t keep those 3 areas of your body clean, you could become a carrier of Methicillin-resistant Staphylococcus aureus (MRSA). MSRA is a bacteria that is resistant to several antibiotics.

According to the Mayo Clinic, MRSA can lead to staph infections that produce painful boils that require surgical draining. In severe cases, they can burrow deep into the skin, leading to life-threatening infections in the bloodstream, bones, joints, heart valves and lungs.

Zubritsky has 1.1 million followers on TikTok and 576,000 on Instagram. Her social media fame has opened up a world of opportunities for the dermatologist.

“My work on social media has provided me with the opportunity to work with the American Academy of Dermatology on their social media campaigns and become an editor in the prestigious Journal of the American Academy of Dermatology,” she told Washington & Jefferson College. “My platform has allowed beauty editors from some of the biggest news outlets and magazines to consult with me on editorial pieces, and I have been featured in Forbes, CNN, Yahoo!, Vogue, Women’s Health, Allure, and many more as an expert dermatologist.”

Two brothers Irish stepdancing to Beyoncé's country hit 'Texas Hold 'Em' is pure delight

The Gardiner Brothers stepping in time to Beyoncé's "Texas Hold 'Em."

In early February 2024, Beyoncé rocked the music world by releasing a surprise new album of country tunes. The album, Renaissance: Act II, includes a song called "Texas Hold 'Em," which shot up the country charts—with a few bumps along the way—and landed Queen Bey at the No.1 spot.

As the first Black female artist to have a song hit No. 1 on Billboard's country music charts, Beyoncé once again proved her popularity, versatility and ability to break barriers without missing a beat. In one fell swoop, she got people who had zero interest in country music to give it a second look, forced country music fans to broaden their own ideas about what country music looks like and prompted conversations about bending and blending musical genres and styles.

And she inspired the Gardiner Brothers to add yet another element to the mix—Irish stepdance.

You know that feeling you get when you walk into a classroom and see someone else's stuff on your desk?

OK, sure, there are no assigned seats, but you've been sitting at the same desk since the first day and everyone knows it.

So why does the guy who sits next to you put his phone, his book, his charger, his lunch, and his laptop in the space that's rightfully yours? It's annoying.

This mom's empowering selfies show off life with an invisible illness.

There are a lot of hard things about living with Crohn's disease. Not being able to talk about it might be the worst one.

Imagine being constantly tired, but in a way that even 15 hours of sleep a day can't cure. Imagine going to dinner, but every time you eat something as simple as a roll of warm bread, it feels like it might've had broken glass inside of it.

Then, it's time to go to the bathroom. Again. Is that the fifth time this hour or the sixth? You've lost track. It's a running joke now — your friends think it's funny, but nobody really talks about what happens when you step away. Because, really, you look fine. Just tired.

A school assignment asked for 3 benefits of slavery. This kid gave the only good answer.

The school assignment was intended to spark debate and discussion — but isn't that part of the problem?

A school assignment asked for 3 "good" reasons for slavery.

It's not uncommon for parents to puzzle over their kids' homework.

Sometimes, it's just been too long since they've done long division for them to be of any help. Or teaching methods have just changed too dramatically since they were in school.

And other times, kids bring home something truly inexplicable.

As much as we'd like to pretend every phrase we utter is a lone star suspended in the space of our own genius, all language has a history. Unfortunately, given humanity's aptitude for treating each other like shit, etymology is fraught with reminders of our very racist world.

Since I have faith that most of you reading want to navigate the world with intelligence and empathy, I figured it'd be useful to share some of the everyday phrases rooted in racist etymology.

Knowledge is power, and the way we use and contextualize our words can make a huge difference in the atmospheres we create.
