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.

Alcohol-Producing Gut Bacteria May Harm Livers—Even if You Don't Drink

Teetotalers might think their liver is safe from the damaging effects of alcohol consumption, but new research is hinting that even non-drinkers and light drinkers might have cause for concern. It turns out a type of gut bacteria is capable of producing alcohol—and enough of it to potentially cause some pretty serious health consequences, including liver disease.

A study led by Jing Yuan at the Capital Institute of Pediatrics in Beijing, China and published in the journal Cell Metabolism offers details. After evaluating a patient with auto-brewery syndrome (ABS), a rare condition brought on by consumption and fermentation of sugary foods that leaves a person with high blood alcohol levels, researchers made an intriguing discovery. Rather than finding fermenting yeast that may have led to the condition, the patient’s stool contained Klebsiella pneumonia, a common gut bacteria capable of producing alcohol. In this subject, K. pneumonia was producing significantly more alcohol than in healthy patients.

The patient also had nonalcoholic fatty liver disease (NAFLD), characterized by fatty deposits in the liver. While many cases of NAFLD are relatively benign, too much fat can become toxic. Examining 43 other subjects with NAFLD, scientists found that that K. pneumonia was both present and potent, pumping out more alcohol than normal in 60 percent of participants with NAFLD. In the control group, a surplus was found in only 6.25 percent.

To further observe a correlation, scientists fed the bacteria to healthy, germ-free mice, who began to see an increase in fat in their livers after only one month. While not conclusive proof that the bacteria prompts NAFLD, it will likely trigger additional research in humans.

It’s not yet known how K. pneumonia acts in concert with the bacterial profile of the gut or what might make someone carrying stronger strains of the bacteria. Luckily, K. pneumonia can be treated with antibiotics. That’s good news for people who might never touch a drink and still find themselves with a damaged liver.

Visit Any National Park for Free on September 28—or Volunteer to Help Maintain Them

By the end of September—which always seems especially busy, even if you’re not a student anymore—you might be ready for a small break from the hustle and bustle. On Saturday, September 28, you can bask in the tranquility of any national park for free, as part of National Public Lands Day.

According to the National Park Service, the holiday has been held on the fourth Saturday of every September since 1994, and it’s also the nation’s largest single-day volunteer effort. It’s up to you whether you’d like to partake in the service side or simply go for a stroll, but there is an added incentive to volunteer: You’ll get a one-day park pass that you can use for free park entry on a different day. Opportunities for volunteering include trail restoration, invasive plant removal, park cleanups, and more; you can see the details and filter by park, state, and/or type of event here.

If you’re not sure how you should celebrate National Public Lands Day, the National Park Service has created a handy flowchart to help you choose the best course of action for you—which might be as simple as sharing your favorite outdoor activity on social media with the hashtag #NPLD.

There are more than 400 areas run by the National Park Service across the U.S., and many of them aren’t parks in the traditional sense of the word; the Statue of Liberty, Alcatraz Island, and countless other monuments and historical sites are also run by the NPS. Wondering if there might be one closer than you thought? Explore parks in your area on this interactive map.

For those of you who can’t take advantage of the free admission on September 28, the National Park Service will also waive all entrance fees for Veteran’s Day on November 11.

And, if you’re wishing a free-admission day existed for museums, you’re in luck—more than 1500 museums will be free to visit on Museum Day, which happens to be this Saturday.
