Go Ahead and Let Out a Deep Sigh Right Now. It’s Actually Good for You

A new study dives into how deep breaths help our lungs.

After breathing a deep sigh, I feel better — don’t you? 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 ETH Zurich, a university in Switzerland, found that deep breaths have an interesting effect on how this fluid interacts with the lungs. The new research was published in the journal Science Advances and 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.

Amazon’s Ring Cameras Push Deeper Into Police and Government Surveillance

Ring has partnered with Flock Safety, making it easier for law enforcement to reach out to Ring doorbell and security camera owners to request footage.

Less than two years after removing a feature that made it easier for law enforcement agencies to request footage from owners of Ring doorbells and other security products, Amazon has partnered with two companies that will help facilitate the same kinds of requests.

Two weeks after rolling out a new product line for 2025, Ring, owned by Amazon, announced a partnership with Flock Safety, as part of its expansion of the Community Requests feature in the Ring Neighbors app. Atlanta-based Flock is a police technology company that sells surveillance technology, including drones, license-plate reading systems and other tools. The announcement follows a partnership Ring entered into with Axon, previously Taser International, which also builds tools for police and military applications.

Taken together, the two partnerships point to Amazon’s Ring division not only reintroducing tools for police to request images or video from Ring customers without a warrant but also to a closer alignment with companies that have ties to police departments, ICE, the Secret Service and branches of the military.

Ring described the process for Community Requests in one of its blog posts. It said an agency that is verified with Axon Evidence, which Axon owns, could submit a community request that includes a specific location and timeframe of an incident and details about what’s being investigated.

The request would appear publicly in the Neighbors feed for people in that area, notifying them with the option to provide footage for that incident.

«If you ignore the request, the agency will not know; your anonymity and videos are protected. The choice is entirely yours,» Ring said in the post.

According to the post, video footage submitted goes directly to Axon Evidence, where it is verified for authenticity.

Community Requests are ‘local,’ according to Ring

In an email responding to our questions, a representative for Ring reiterated the process for Community Requests, adding that «only local public safety agencies can initiate Community Requests.»

The localized area submitted is limited to half a square mile, and those agencies don’t have access to information on who will receive a request to share footage or how many Ring users are in a given area, according to Ring. The company says those requesting information must follow community guidelines.

According to Ring’s website, only local and county entities — whether they’re law enforcement, nonprofits, or local government — can set up a Neighbors Verified account. While federal agencies or local branches of federal agencies might be customers of Axon or Flock, they wouldn’t be eligible for a Neighbors Verified account and would not be eligible to file a Community Request, even if it were done on their behalf by a third party such as Axon or Flock, the Ring representative confirmed to CNET.

The partnerships would give those agencies more entry points for creating these requests. Amazon hinted in one of its blog posts that it may add partnerships with other companies. Community Requests can only come from agencies that have been verified by a third party, such as Flock or Axon, and by Ring as well.

Back in 2018, when Flock Safety was a nascent startup, it set up its own cameras in neighborhoods to provide surveillance to fight crime.

Surveillance bystanders

While the footage from Ring devices is only given to local organizations by permission of the footage’s owner, that doesn’t mean other people — such as someone walking their dog or children playing in a neighborhood — are free from potential privacy issues if they’re captured on camera.

«This arrangement creates a tricky problem from a privacy standpoint for consumers because the people who never signed up for surveillance in the first place could be watched, and they never agreed to that,» said Erik Avakian, a technical counselor at Info-Tech Research Group and the former chief information security officer for the Commonwealth of Pennsylvania.

Avakian said that making Ring footage availability opt-in still doesn’t address the issue of what happens to footage once it’s in the hands of law enforcement or other groups.

«It could be used for other investigations, shared with others, or perhaps even used to capture biometrics and personal information like facial recognition features,» he said. «The videos might also end up revealing more about neighbors, visitors, or passersby than about the actual incident itself.»

He said one solution would be to blur out any individuals or identifiable artifacts from footage if it’s not part of the investigation. Regardless of whether that’s possible or not, Avakian said that companies such as Ring and those requesting footage should be transparent about how videos or images will be used, how long data will be stored, and if it’s shared with anyone else.

Mesh policing

What Ring and local law enforcement are doing with Community Requests may create some efficiencies for agencies that are stretched thin and don’t have the resources to gather as much evidence as what doorbell and security camera owners may be able to provide.

«Crime isn’t slowing down, but police resources are stretched thinner than ever,» said Ryan Schonfeld, co-founder and CEO of HiveWatch, which uses AI technology to create security ecosystems.

«Technology integration gives a single officer access to necessary data that was previously unavailable, doing the work that would have required an entire team,» Schonfeld said. «If we want crimes solved and public safety maintained, we need to embrace the interoperability that makes it possible with the resources we actually have.»
