In a matter of days, we went from seeing no one wearing a mask and gloves in public to just about everyone wearing a mask and gloves in public. The goal of wearing personal protective equipment, is to prevent transmitting or acquiring COVID-19.
However, when this equipment isn’t used properly it can be more dangerous than not wearing any at all.
If you’ve been told to use gloves by an employer or you feel they are best for your personal protection, it’s very important to take the proper safety precautions.
Jacquelyn Gill, a paleoecologist and Associate Professor of climate science at the University of Maine, is used to wearing gloves when she does field work. As an ICE Age ecologist, she has to be careful not to contaminate ancient specimens she comes across in the frozen tundra.
So to inform the public on the safe way to wear gloves, she took to Twitter.
If all of her wisdom is news to you, don’t feel bad, most people aren’t professionally trained to wear gloves.
Based on what I’m seeing in my weekly grocery trip, people need a primer on how to use disposable gloves properly. As a scientist who wears gloves to protect me from lethal chemicals (abd to avoid contaminating ice age specimens), let me share some tips: — Dr. Jacquelyn Gill (@JacquelynGill) April 5, 2020
One of the most important things to remember: the point of gloves is not to not prevent you from “absorbing” the virus through your skin. If your skin is hydrated and you don’t have open wounds, your body’s natural defenses will prevent transmission through your skin. — Dr. Jacquelyn Gill (@JacquelynGill) April 5, 2020
(With all the handwashing, your hands may be cracked and dry: keep them hydrated with heavy duty hand creams!) — Dr. Jacquelyn Gill (@JacquelynGill) April 5, 2020
The big benefit to wearing gloves is that they’re disposable.
So why wear gloves? They’re disposable! If you touch a surface lots of other people touched, like a pin pad at a checkout counter or a door handle, you can throw them away and avoid transmitting any germs (like coronavirus) to your phone, face, car door, debit card, keys, etc. — Dr. Jacquelyn Gill (@JacquelynGill) April 5, 2020
Gloves will not prevent you from transferring germs from a contaminated surface to an I contaminated one! They aren’t anti-microbial. If you touch a doorknob with gloves on, then touch your face WITH THOSE SAME GLOVES, you’ve transmitted germs from the doorknob to your face. — Dr. Jacquelyn Gill (@JacquelynGill) April 5, 2020
You can easily transmit the virus while wearing gloves.
Things I saw people doing while wearing gloves:
– opening a soda bottle and taking a drink
– touching their glasses
– adjusting their masks
– touching their car keys, debit card
– using their phone
*All while shopping in a store and handling groceries, their carts, etc.* — Dr. Jacquelyn Gill (@JacquelynGill) April 5, 2020
Even though you’re wearing gloves, you still have to wash your hands.
The only way gloves are effective is if you change them as often as you should wash or sanitize* your hands.
Read that out loud. Again. Make it stick.
*Good hand-washing with soap is more effective than sanitizer, but it’s not always something we can do outside the house. — Dr. Jacquelyn Gill (@JacquelynGill) April 5, 2020
If you have gloves on, and you’ve touched something, treat your hands as if they were contaminated. Period. Treat the gloves as an extra layer of skin that you can shed BEFORE you touch your face, your car door, or any surface you don’t want to contaminate. — Dr. Jacquelyn Gill (@JacquelynGill) April 5, 2020
“But doesn’t that mean you have to change your gloves a lot?”
Yep!
It also means you can get by without them if you’re washing your hands and paying attention to what you touch. Or save them for things like the gas pump or other single uses where you can’t wash your hands. — Dr. Jacquelyn Gill (@JacquelynGill) April 5, 2020
You should not re-use gloves.
Gloves start to lose effectiveness with use, and not all gloves are the same (there are many kinds!) so look up how long you can safely wear yours.
Many research-grade gloves are designed to tear if they have a defect, so if you put them on and they rip, that’s good! It means there was a tiny hole or a weak spot. Just get another one. — Dr. Jacquelyn Gill (@JacquelynGill) April 5, 2020
Be careful if you’re thinking about sanitizing your gloves. You may be reducing their effectiveness, depending on the chemicals used. There are lots of charts online that tell you what your specific type of gloves will be effective against. — Dr. Jacquelyn Gill (@JacquelynGill) April 5, 2020
And finally, please safely dispose of your used gloves in the trash. Bag them up in your car if you can’t find an outdoor garbage can. Don’t throw them on the ground for someone else to pick up, or where they could potentially harm wildlife. — Dr. Jacquelyn Gill (@JacquelynGill) April 5, 2020
Don’t wash and re-use your gloves.
A lot of folks are asking about washing and re-using disposable gloves:
Think of them like condoms, folks. Single-use and disposable. That’s what they were designed for. They start to wear out and and fail rates increase within 15-30 minutes. That’s why hospitals need so many. — Dr. Jacquelyn Gill (@JacquelynGill) April 5, 2020
This seems obvious, but …
I can’t believe I need to add this, but: don’t remove your gloves with your teeth. Ever. Under any circumstances. Even if we aren’t in a pandemic. Even if you just chopped up some jalapeños. If you didn’t want it on your hands, you don’t want in your mouth. — Dr. Jacquelyn Gill (@JacquelynGill) April 5, 2020
PS It’s okay if you didn’t know some or all of this. Disposable gloves are something most of us don’t use on a daily basis. We’re all having to learn new things to get through this. Take care of one another, stay strong, stay healthy. — Dr. Jacquelyn Gill (@JacquelynGill) April 5, 2020
Gill’s tweet thread discusses the importance of removing gloves safely to prevent the spread of disease. Here’s the Centers for Disease Controls tips on how to do so properly.
A seven-step guide from the CDC outlines how to properly remove gloves to avoid unintentional germ transmission.
– Grasp the outside of one glove at the wrist. Do not touch your bare skin.
– Peel the glove away from your body, pulling it inside out.
– Hold the glove you just removed in your gloved hand.
– Peel off the second glove by putting your fingers inside the glove at the bottom of your wrist.
– Turn the second glove inside out while pulling it away from your body, leaving the first glove inside the second.
– Dispose of the gloves safely. Do not reuse the gloves.
– Clean your hand immediately after removing gloves.
The modern workday unfolds largely indoors. Long hours spent commuting, sitting in meetings and staring at screens can make time outdoors feel like a luxury. Finding time for nature in an already packed workday can feel impossible, especially if you think nature only “counts” when it involves hiking boots and camping gear.
But a growing body of research suggests that nature’s benefits don’t require an exotic vacation getaway or weekend adventure. Even brief, routine interactions with green space can reduce stress, improve mood and promote overall well-being.
I spent the spring of 2026 teaching and studying urban landscapes in Denmark, a country consistently ranked among the happiest in the world. I expected to find thoughtfully designed parks, courtyards and bicycle paths. I did see those things. But what surprised me was how seamlessly people moved through those spaces as part of their ordinary lives.
These green spaces weren’t aspirational destinations, reserved for special occasions. They were places to eat lunch, meet friends, walk through on the way home from work, or just pause for a few quiet moments. Getting outside seemed a part of the natural rhythm of the day.
Denmark‘s outdoor culture stemmed not only from the creation of a meticulously planned network of parks, but also from the way green spaces were fundamentally woven into the routines of everyday life.

Everyday parks, everyday benefits
Evidence linking time spent in nature with health benefits has increasingly shaped public policy. In the U.S., for example, the National Park Service’s Healthy Parks Healthy People and ParkRx initiatives reflect a growing recognition that access to parks contributes to well-being.
For many Americans, however, the word “park” brings to mind iconic national parks such as Yellowstone, Yosemite or the Grand Canyon. Yet visiting parks of all kinds can improve your overall health. The greatest public health value may come not from the parks people visit once in a lifetime but from those close enough to visit again and again.
My own research on Civil War battlefield parks illustrates this point. These are parks that were established to commemorate historic conflicts that were frequently fought on the fringes of major metropolitan areas. Consequently, many of these landscapes preserve forests, grasslands and trails within easy reach of millions of Americans.
Because they’re accessible without extensive travel or planning, they can become places people return to repeatedly – such as during a lunch break or after work. Reframing the notion of “park” opens up millions of acres of land for everyday uses.
Designing for everyday nature
At the University of Richmond, where I work, a stream restoration projects became an opportunity to rethink how nature fits into campus life. Landscape architects designed an Eco-Corridor, as the project became known. It has walking paths, gathering spaces and seating areas for quiet reflection alongside flowing streams and native vegetation.
The result was a landscape that supports biodiversity and improves water quality while also creating places for students, faculty and staff to walk between meetings, eat lunch alfresco or spend a few quiet moments outside during the workday. Its ongoing care depends on an army of volunteers who spread mulch, remove invasive plants and tend the community garden. For these volunteers, stewardship between classes and meetings meant another opportunity to interact with nature.

What we learned was that nature doesn’t have to compete with work, studying or everyday responsibilities. Thoughtful landscape design can make spending time outdoors, even if only for a few short minutes, feel like a normal part of the day.
According to the Guinness Book of World Records, the oldest person lived to the ripe age of 122 years old. Such a lifespan is an incredible feat, but what if the average person could beat that record by 34 years? Recent research done in Russia has led scientists to believe that the average human lifespan could be up to 156 years.
The researchers at Skoltech Biomed Technologies Center developed a mathematical model that allowed them to “switch on” a variety of aging mechanisms. This allowed them to calculate a human’s lifespan where mortality risk never increased with age. After experimenting with different scenarios and conditions, they found the biggest barriers to longevity were caused by non-renewable tissues and somatic mutations.
What are these barriers against longer life?
Somatic mutations are DNA changes within a cell. They accumulate over time during a human’s life and cannot be reversed with any existing therapy. These DNA errors that pile up in our cells contribute to the aging process.
Many human organs like the liver and skin continually replace cells and regrow damaged portions of themselves. However, there are two organs that can’t do this: the brain and the heart. Brain tissue (neurons) and heart tissue (cardiomyocytes) cannot regenerate. This proves to be the most prominent biological limit that shortens our lifespans. This explains why issues like dementia and heart disease are prominent causes of death and morbidity later in life. Since those organs’ tissues don’t replace damaged cells, they’re prone to irrevocably decline over time.
“The key finding of the study is the discovery of substantial differences between tissue types. Neurons and cardiomyocytes, which lack the ability to divide, turned out to be the main limiting factors: when all other causes of aging are eliminated, somatic mutations alone reduce the theoretical median lifespan from 1,759 years (for a hypothetical non-aging human organism) to 156 years,” said Evgeny Efimov, a research intern at the Skoltech Biomed Technologies Center, researcher at AIRI, and one of the key authors of the study.
This suggests that somatic mutations and DNA damage is what ultimately prevents humans from living indefinitely, even if our brains and hearts regenerated cells like other organs.
So what’s next?
Now knowing these biological limitations, the researchers hope to study other areas of aging impacting the human lifespan that could plausibly be reversed. This includes mitochondrial dysfunction, telomere shortening, epigenetic drift, and loss of proteostasis.
The hope is to have a clearer priority list of issues for future therapies to tackle. This is not just to possibly extend life, but to improve lives in general. By developing a fully comprehensive theory of aging, Skoltech hopes to pinpoint which aspects of aging are within our scope to address. After all, thoroughly studying each puzzle piece that makes up human life gives us a better understanding of the whole.
Of course, other impactful factors in a person’s lifespan can be addressed today. As most know, things like diet, sleep, and exercise are among them. A person’s living environment can also negatively impact their lifespan if it doesn’t have clean air, access to clean water, and so on.
For now, the best method for living long is to follow instructions from your physician. Whether you make it to 156 years or not, living well is best for whatever time you’re given.
In the U.S., as of mid-2026, more than 30 states have passed laws banning or restricting cellphones in K–12 classrooms; in 2023, the U.S. surgeon general issued a formal advisory on social media and children’s and adolescents’ mental health; and bestselling books tell parents that smartphones are “rewiring” their children’s brains.
These concerns and policies are part of a quickly changing national and international conversation around how young people spend time on screens and its relationship to their overall health and development. My reading of the mounting research on this issue across disciplines is that the popular narrative blaming screens and smartphones for an adolescent mental health crisis runs well ahead of the current evidence.
I study adolescent digital media use and its influence on social, emotional and academic outcomes. A growing body of research suggests that one-size-fits-all solutions are not the answer and that managing appropriate use of digital media needs to take into account a child’s developmental milestones, how parents and adults around them use media, and the ways kids use it to connect and learn with friends and family.
Screen time: From monolith to multifaceted
Wide adoption of digital media and the internet broadened the range of experiences young people could have online. At the same time, the digital age introduced newfound uncertainties. As with the advent of radio, comic books and arcades, adults worried about how children might interact with or be affected by internet use.
Policies introduced by the academy in 2013 and 2016 continued to advise that school-age kids and adolescents – those ages 5 to 18 – be restricted to no more than two hours of “entertainment” screen time a day. The goal was to curb risks associated with heavy media use, among them disrupted sleep, online safety, cyberbullying and physical inactivity.
Originally created for young people’s engagement with stationary media that tend to be confined to one room or context – for example, watching television – these hourly limits became outdated with the integration of smartphones and other digital devices into everyday life. Compared with watching television, online media was far more difficult to track and define, and more nuanced in its use.
In January 2026, the American Academy of Pediatrics retired its decade-old framework that had largely organized its advice around hourly screen limits. The new policy statement on children, adolescents and digital media diverges from this blanket approach. Instead, it suggests parents consider the larger picture in which this media use exists rather than lumping all screen use together.
Both the World Health Organization and the American Academy of Pediatrics also recommend that when children under 24 months use screens, they should be limited to content and devices that encourage children and caregivers to interact. For ages 2 to 5, screen time – including TV and interactive apps on devices – may be extended to more solo use, provided it’s high-quality digital media designed around learning goals in mathematics and reading. But recreational use should be limited to roughly an hour per day.
For school-age children and teens, the newest guidance has begun to step away from fixed screen time limits and asks families to weigh online activity in the context of everyday life.
Doing so recognizes that a child’s digital experiences are shaped by diverse factors rather than the hours spent online. Current guidelines call on caregivers to distinguish among types of media, from television and social media to video games and interacting with artificial intelligence chatbots. They also call for taking into account a child’s individual characteristics, such as their interests and personality, family members’ own use of screens, and the type of content children are spending time on.
Rethinking screen time
Moving beyond strict screen time limits includes questioning the kind of digital activities kids and adolescents participate in. Do the activities encourage time spent interacting with others online, which can help young people develop important skills and competencies?
Scrolling an algorithm-based, auto-playing video feed likely does not equate to the same opportunities as video-chatting with friends, creating digital art or working with teammates in a multiplayer game. Research suggests these different uses relate to development in different ways and can help kids develop varying skill sets pertaining to everyday life and schooling.
Indeed, a large review of current research found that young people who take part in a range of digital activities, such as browsing the web, online gaming or interacting on social media, show positive associations with social connection, identity exploration, civic participation and learning.
The current evidence suggests parents and caregivers are best positioned to be digital instructors. Cutting children off altogether can carry its own risks for social and emotional development. Caregiver mediation of children’s screen time can produce widely different outcomes and effects, depending on whether the guidance is supportive or controlling.
Considering your own digital media use is the first step: Are family members engaging in problematic or heavy media use that children in the household might emulate? What applications and uses are most common in the family, and what positive or negative effects might they have, depending on the child’s age? How could these digital activities be safely integrated with other everyday experiences to increase their benefit for children? Conversely, what online time might be better spent on face-to-face experiences?
The American Academy of Pediatrics’ Family Media Plan tool turns these ideas into concrete questions. For example, it recommends working out what each child needs from digital technology, what activities screens might be crowding out, and where their family or household can build in screen-free time. The recommendation is to talk with each child about why they are drawn to particular apps or online activities, what they encounter while browsing, and what might be lost when kids bring phones to gatherings such as mealtimes.
The debate over young people’s screen time is not going away. But the most up-to-date guidelines, and the growing body of research behind them, make a strong case for a more holistic approach. The guidelines treat digital media as a complex, diverse and evolving environment that children need to learn to navigate in the digital age. The risks and rewards depend, as with any developmental setting, on the child, the content and what online time might be crowding out.
