Sighing Deeply Is Actually Good for You. Here’s Why
A study dives into how deep breaths help our lungs.
Do you feel better after breathing a deep sigh? It’s relaxing. And it turns out there’s a good reason why we feel relief after big breaths, It comes down to a special fluid inside our lungs. The liquid — pulmonary surfactant — helps our lungs work. Without it, we’d be in serious trouble. But researchers at Swiss university ETH Zurich found that deep breaths have an interesting effect on how this fluid interacts with the lungs.
The new research, published in the journal Science Advances, could have meaningful implications for future medicine and therapies.

‘Magic’ lung fluid to the rescue
For a long time, scientists have been interested in how this fluid helps us breathe. In the 1980s, research into this area resulted in a life-saving treatment for babies born prematurely with underdeveloped lungs.
By extracting fluid from animal lungs and injecting it into those of premature infants, doctors were able to reduce respiratory distress syndrome from developing right after birth. The fluid reduces surface stress in the lungs.
«This surface stress influences how compliant the lungs are,» said ETH Zurich professor Jan Vermant. «The more compliant the lungs are, the less resistance there is to expansion and contraction — and the easier it is to breathe.»
Breathing deep to ease tension
The research team wanted to see how lung fluid behaved when it was stretched and recompressed, so they simulated the movements of normal and deep breaths in the lab.
They measured the fluid’s surface stress in each case and compared the data. The researchers found that surface stress decreases significantly after a deep breath.
The utmost layer of the thin film that the fluid leaves on a lung settles and hardens over time.
«Directly at the boundary with the air, there is a slightly stiffer surface layer,» said Maria Novaes-Silva, a doctoral student in Vermant’s research group and the study’s first author. She said that the pronounced stretching and compression of the pulmonary fluid that comes with a deep sigh actually rearranges the surface layer’s composition.
So, after you let out a deep breath, it becomes easier for you to breathe. That’s why we feel a sense of relief from a deep sigh.
An ETH Zurich spokesperson said that clinical practice has also found that breathing becomes increasingly complex with constant shallow breaths. So, the lab measurements seem to follow real-world observations.
The researchers theorize that this study may contribute to a better understanding of adult lung failure.

How Team USA’s Olympic Skiers and Snowboarders Got an Edge From Google AI
Google engineers hit the slopes with Team USA’s skiers and snowboarders to build a custom AI training tool.
Team USA’s skiers and snowboarders are going home with some new hardware, including a few gold medals, from the 2026 Olympics. Along with the years of hard work that go into being an Olympic athlete, this year’s crew had an extra edge in their training thanks to a custom AI tool from Google Cloud.
US Ski and Snowboard, the governing body for the US national teams, oversees the training of the best skiers and snowboarders in the country to prepare them for big events, such as national championships and the Olympics. The organization partnered with Google Cloud to build an AI tool to offer more insight into how athletes are training and performing on the slopes.
Video review is a big part of winter sports training. A coach will literally stand on the sidelines recording an athlete’s run, then review the footage with them afterward to spot errors. But this process is somewhat dated, Anouk Patty, chief of sport at US Ski and Snowboard, told me. That’s where Google came in, bringing new AI-powered data insights to the training process.
Google Cloud engineers hit the slopes with the skiers and snowboarders to understand how to build an actually useful AI model for athletic training. They used video footage as the base of the currently unnamed AI tool. Gemini did a frame-by-frame analysis of the video, which was then fed into spatial intelligence models from Google DeepMind. Those models were able to take the 2D rendering of the athlete from the video and transform it into a 3D skeleton of an athlete as they contort and twist on runs.
Final touches from Gemini help the AI tool analyze the physics in the pixels, according to Ravi Rajamani, global head of Google’s AI Blackbelt team. which worked on the project. Coaches and athletes told the engineers the specific metrics they wanted to track — speed, rotation, trajectory — and the Google engineers coded the model to make it easy to monitor them and compare between different videos. There’s also a chat interface to ask Gemini questions about performance.
«From just a video, we are actually able to recreate it in 3D, so you don’t need expensive equipment, [like] sensors, that get in the way of an athlete performing,» Rajamani said.
Coaches are undeniably the experts on the mountain, but the AI can act as a kind of gut check. The data can help confirm or deny what coaches are seeing and give them extra insight into the specifics of each athlete’s performance. It can catch things that humans would struggle to see with the naked eye or in poor video quality, like where an athlete was looking while doing a trick and the exact speed and angle of a rotation.
«It’s data that they wouldn’t otherwise have,» Patty said. The 3D skeleton is especially helpful because it makes it easier to see movement obscured by the puffy jackets and pants athletes wear, she said.
For elite athletes in skiing and snowboarding, making small adjustments can mean the difference between a gold medal and no medal at all. Technological advances in training are meant to help athletes get every available tool for improvement.
«You’re always trying to find that 1% that can make the difference for an athlete to get them on the podium or to win,» Patty said. It can also democratize coaching. «It’s a way for every coach who’s out there in a club working with young athletes to have that level of understanding of what an athlete should do that the national team athletes have.»
For Google, this purpose-built AI tool is «the tip of the iceberg,» Rajamani said. There are a lot of potential future use cases, including expanding the base model to be customized to other sports. It also lays the foundation for work in sports medicine, physical therapy, robotics and ergonomics — disciplines where understanding body positioning is important. But for now, there’s satisfaction in knowing the AI was built to actually help real athletes.
«This was not a case of tech engineers building something in the lab and handing it over,» Rajamani said. «This is a real-world problem that we are solving. For us, the motivation was building a tool that provides a true competitive advantage for our athletes.»

Virtual Boy Review: Nintendo’s Oddest Switch Accessory Yet Is an Immersive ’90s Museum
No one needs a Virtual Boy. But I always wanted one. And now it’s living with me at last.
On my desk is a Nintendo device that looks like equipment stolen from a cyberpunk optical shop. It’s big, it’s red and black, it sits on a tripod, it has an eyepiece, and it has a Nintendo Switch 2 nestled inside. Hello, Virtual Boy, you’re back.
Nintendo has made a lot of weird consoles over the years, but the Virtual Boy was the weirdest. And the shortest lived. Released in 1995 and discontinued a year later, it lived for a blink of an eye during my final year in college. I never really had time to consider buying one.
It would have been perfect for me, a Game Boy fan who was in love with the idea of VR even back then. Nintendo has been flirting with virtual reality in various forms for decades, and the Virtual Boy was the biggest swing. But it wasn’t VR at all, really. It was a 3D game console in red and black monochrome, a 3D Game Boy in tripod form.
I’m setting the stage because right now you can order a $100 Virtual Boy recreation that’s a big, strange Switch accessory. It’s staring at me now, taking up a lot of space. It’s too big to fit in a bag. It’s a tabletop console, really, and Nintendo has created this Virtual Boy viewer as a way to play a set of free-with-subscription games on the Switch and Switch 2.
Is it worth your money? I’d call it a museum-piece collectible, not a serious piece of gaming hardware. Still, my kid stuck his head in, played 3D Wario Land, and came out declaring it was really cool. He loves old retro games. But I don’t know how often he’ll pop his head back in.
Nintendo’s first stab at 3D now feels like a museum piece
For comparison, I pulled my old Nintendo 3DS XL out of the drawer where it had been tucked away and booted it up, marveling again that Nintendo actually made a glasses-free 3D game handheld once upon a time. The 3DS is a far more capable and advanced game system, but consider the Virtual Boy an ancient attempt to get there first.
The Virtual Boy was a monochrome red-and-black LED display system, a tabletop-only device that was neither handheld nor TV-connected. The Nintendo Switch’s tabletop-style game modes feel like a bit of an evolutionary link to the Virtual Boy, so it’s poetic that the Switch pops into the new Virtual Boy to power the games and provide the display.
The plastic Virtual Boy is just an odd set of VR goggles for the Switch, but with a red filter on the lenses. Also, you can’t wear it. You keep your head stuck in it.
Awkward and easy to use
All the trappings on this recreation look like the old Virtual Boy but don’t work: You can see a simulated headphone jack, controller port, a sort of knob on top. I just unsnap the plastic case and slide the Switch in, carefully, and then snap it back over. That’s all it is.
To control it, you use the Switch controllers detached or another Switch-compatible controller. Launching the Virtual Boy app — free on the eShop, but you need a Switch Online Plus Expansion Pack account, which costs $50 a year, or $80 for a family membership — splits the Switch display into two smaller, distorted screens. In the Virtual Boy, it looks properly 3D. When I’m done playing, I pop the Switch back out.
As I said in my first hands-on, the big foam-covered eyepiece is more than wide enough for big glasses, and was fine to dip my face into. Getting a comfortable angle to stay playing for a while is another challenge. The Virtual Boy’s included tripod-like stand can adjust the angle, but not as wide as I’d like. I’m sort of hunched over while playing, which gives me a bit of pain. Leaning on the table with my controllers in hand helps.
The red-lensed front eyepiece can be removed, and a later software update will allow Virtual Boy games to be played in several color mixes beyond red and black. Also, you can unscrew an inner bracket to hold the Switch 2 and swap in an included Switch-sized bracket instead. The Switch Lite doesn’t work with the Virtual Boy, however.
The weirdness is my type of indie
All you get right now are seven of the 16 games Nintendo has promised to release for the Virtual Boy. Believe it or not, there were only 22 games ever released for this system. The 16 will include two that were never released before, which is a fun collector’s novelty.
But what’s amazing to me now is that, sinking into these oddball retro games with their pixelated NES-slash-Game Boy aesthetics in red and black, they feel weirdly timely. The janky, oddball, almost-parallel-universe Nintendo vibe feels like the indie retro aesthetic that’s been big for a while now. After all these years, is the Virtual Boy now finally awesome?
Games like UFO 50 (a compilation of new indie games made to feel like an archive of ’80s games for a console that never was) and indie consoles like Panic Playdate (still my favorite black and white mini handheld, a home for all sorts of homebrew retro games) match my feeling diving into these Virtual Boy games and figuring them out.
Wario Land is probably the best: A side-scrolling Wario game with multiple depth levels, it gives me Game Boy Mario game vibes. Golf has multiple holes and an aiming system, and it’s relaxed and basic (and hard to perfect). 3D Tetris has you dropping blocks down a well to fill in layers, with a Tron-like puzzle feel. Red Alert’s wireframe 3D shooter design is like Star Fox, but boiled all the way down to simple vector lines. Galactic Pinball has several tables, and it’s some lovely, very old-school 3D Nintendo pinball fun. Teleroboxer is Punch-Out with robots, with a style that also reminds me of the early Switch game Arms. And The Mansion of Innsmouth is a creepy 3D dungeon-crawling game (in Japanese) where you try to get to exits before time runs out… or monsters get you.
The remaining games coming this year include Mario Tennis, another Tetris game, a wireframe 3D racer, a 3D reinvention of the original Mario Bros. game called Mario Clash and a 3D Space Invaders. By the end of Nintendo’s release schedule, a good chunk of Virtual Boy’s catalog will be there.
A novelty that’s niche as hell
Worth it? Again, if you love weird and retro, and are intrigued by lost Nintendo 3D games, then yes. But if you’re looking for cutting-edge, then no.
Keep in mind: You can buy a cheaper $25 cardboard set of goggles for the Switch that lets you play the Virtual Boy games, too (or use the old Labo VR goggles Nintendo made in 2019, if you have them). That’s a more sensible path. There are even unofficial emulators for Virtual Boy games on the Meta Quest and Apple Vision Pro. But who said the Virtual Boy was sensible?
A Nintendo game system that’s a big set of red goggles on a tripod is inherently absurd. And I welcome its weird footprint in my home, because that’s exactly who I am. But it’s also a testament to Nintendo’s perpetual interest in the bleeding edge of gaming. VR, glasses-free 3D, AR, modular consoles… Nintendo’s poking around the edges.
Is the Virtual Boy a sign that Nintendo could make its own VR or AR game system again someday soon, or as an extension of the Switch 2? Who knows? Shigeru Miyamoto, Nintendo’s legendary video game designer, sounded intrigued and elusive about it when I asked him last year. But there’s never any real way to guess where Nintendo’s heading. The Virtual Boy is a museum-piece reminder of that.
