You might have seen an unusual home hack known as “house burping” popping up across your socials recently. This trendy new term is actually a well-known practice in Germany, and (thankfully) has nothing to do with belching behind closed doors.

The ritual, called “lüften” in Germany, which translates to “ventilate,” is simple. Every day (many people do it semi-ceremoniously at the same time each day), you open the windows throughout your home. This is done even in winter. Yes, even with those incoming arctic blasts! And it’s even mandatory in some German leases.

Folks in America seem to liken it to burping a baby, hence the new moniker. But no matter what you call it, house burping/lüften allows stale, moisture-laden air to escape, pushing out odors and airborne bacteria. Many are touting it as the ultimate “mom hack” for keeping sickness away.

It was even hailed as “one of the cheapest and most effective ways” to prevent the spread of COVID during the pandemic.

Whether or not lüften is 100% beneficial is up for debate, as one 2021 study held in Germany noted that it may negatively affect energy efficiency. This is certainly something to consider in the United States, where electricity costs have skyrocketed. But if you stick to the 5-10 minutes that is suggested and widely practiced, that shouldn’t pose too much of an issue.

Thankfully, no one has to endure an actual ten-minute burp.

There are also more or less optimal times for burping/airing out your house, including first thing in the morning, after a shower or cooking, and after people have come over for a visit, as reported by Today.

Perhaps the best bit about all this is seeing the amazed reactions (and pretty funny quips) from Germans upon hearing that “America discovers fresh air.”

“When Americans find out about fresh air and call it house burping…hilarious.”

“It’s as if it’s America’s first day on earth I swear.”

“Tiktok trend? Opening your windows? Seriously?”

“America finding out what windows are for.”

“Next America will discover natural light…”

But hey, in our defense, many Americans do, in fact, already have this in their daily routine.

"I call it letting the house breathe and I do it every morning while I have my coffee 😁," one person commented on one particularly viral house burping video.

"First thing I do after I get my kids up and changed is open all of the blinds and windows while they eat. Good for the house, good for me lol," added another viewer.

So, there!

But truth be told, this really does show how so many of these fancy, newfangled TikTok trends are actually just zhuzhed up bits of common wisdom. Doesn’t make them any less wise, though.

Nearly every parent hopes their child will be better off than they are: smarter, more secure, and more well-adjusted. Many parents see this as a stamp of successful parenting, but something has changed for children growing up today. While younger generations are known for their empathy, their cognitive capabilities seem to be lagging behind those of previous generations for the first time in history.

Dr. Jared Cooney Horvath, a teacher turned cognitive neuroscientist who focuses on human learning, appeared before Congress to discuss concerns about cognitive development in children. In his address to the members of Congress, he says, "A sad fact that our generation has to face is this: our kids are less cognitively capable than we were at their age. Since we've been standardizing and measuring cognitive development since the late 1800s, every generation has outperformed their parents, and that's exactly what we want. We want sharper kids."

Horvath explains that the reason this happens is that each generation has gone to school longer than the previous generation. Gen Z is no exception to the longer duration of time spent in school, but they're the first ones who aren't meeting this normal increase in cognitive development. According to the cognitive neuroscientist, the decline is due to the introduction of screens in the classroom, which started around 2010.

"Across 80 countries, as Jean was just saying, if you look at the data, once countries adopt digital technology widely in schools, performance goes down significantly. To the point where kids who use computers about five hours per day in school for learning purposes will score over two-thirds of a standard deviation less than kids who rarely or never touch tech at school," Horvath reveals.

In most cases, the decline in performance doesn't result in better strategies. The neuroscientist shares that the standardized testing has been adjusted to accommodate lower expectations and shorter attention spans. This is an approach that educators, scientists, and researchers went to Capitol Hill to express wasn't working. But not every country is taking the approach of lowering standards to meet lowered cognitive ability. Denmark went in the opposite direction when it realized their students were slipping behind.

France24 recently interviewed educators in Denmark following their seemingly novel approach to students struggling with cognitive development. Since the beginning of the 2025/2026 school year, Denmark has not only been having students turn in their cellphones, but they've also taken tablets, laptops, and computers out of the classroom. No more digital learning for the majority of the school day. Danes went old school by bringing back physical textbooks, workbooks, and writing assignments. The results have been undeniable. Even the students can't seem to deny the success of the countrywide shift in educational approach.

"I think the biggest issue has been that, because we kind of got rid of the books and started using screens instead, that we've noticed that a lot of the kids have trouble concentrating, so it's pretty easy to swipe with three fingers over to a different screen and have a video game going, for example, in class," Copenhagen English teacher, Islam Dijab tells France24.

Now, instead of computers being part of every lesson, Denmark uses computers very sparingly and with strict supervision. One student says that it has been nice not having screen time at school because she loves to read and write. But it wasn't just the lack of attention span children were developing, they were also developing low self-esteem and poor mental health due to the amount of time spent on devices.

The data showing the negative impact of screens on teens' brains has prompted a nationwide change in Denmark that extends outside of the classroom. Afterschool activities are eliminating or extremely limiting electronic use. There is also a national No Phone Day that encourages everyone to put away their devices for the day, and Imran Rashid, a physician and digital health expert, is petitioning parliament to ban social media use for children under the age of 15. The no phone movement in Denmark is a nationwide effort that hopes to right the ship before another generation feels the effects.
