“Women with active sunlight exposure habits experience a lower mortality rate than women who avoid sun exposure,” concludes a studypublished March 21 in the Journal of Internal Medicine. It’s a surprisingly counterintuitive conclusion in our “cover-up” culture, but it turns out regular sun exposure is not only good for you, it’s a major factor to health and longevity.
The authors of the study, led by Pelle Lindqvist, MD, of Karolinska University Hospital in Huddinge, Sweden, studied nearly 30,000 Swedish women over 20 years. Compared to those who avoided sun exposure, women with active sun exposure habits were mainly at a lower risk of cardiovascular disease (CVD) and non-cancer/non-CVD death.
And here’s an even more radical conclusion: The researchers found that avoiding sun exposure is on par with smoking as a health risk. Senior citizen smokers in the study with the active sun-exposure habits had a 2-year longer life expectancy compared with smokers who avoided sun exposure. Compared to the highest sun exposure group, life expectancy of avoiders of sun exposure was reduced by 0.6–2.1 years. “Nonsmokers who avoided sun exposure had a life expectancy similar to smokers in the highest sun exposure group, indicating that avoidance of sun exposure is a risk factor for death of a similar magnitude as smoking.”
The study, of course, acknowledges that sun exposure can lead to an increased risk of skin cancer. But they found that subjects with regular sun exposure who develop skin cancer had a better prognosis than subjects who stayed out of the sun. It’s also a bit of a statistical paradox, because the increase in survival and longevity for women who have active sun exposure in their lives also inherently increases their chances to develop cancer.
The study’s authors do own up to limitations of the study. They did not track exercise for the subjects, so there is no way to compare sun exposure to leading a healthy lifestyle. Also it’s not known if the sun exposure’s positive effects are related to the benefits of Vitamin D production or some other effect of exposure.
In and interview with Medscape Medical News, Lindqvist stayed measured about the findings, explaining that women should not overexpose themselves to sun, but underexposure may be even more dangerous than people think.
“We know in our population, there are three big lifestyle factors [that endanger health]: smoking, being overweight, and inactivity,” he said. “Now we know there is a fourth — avoiding sun exposure.”
“Avoid screens before bed” is one of the most common pieces of sleep advice. But what if the real problem isn’t screen time − it’s the way we use social media at night?
Sleep deprivation is one of the most widespread yet overlooked public health issues, especially among young adults and adolescents.
At the same time, social media is nearly universal among young adults, with 84% using at least one platform daily. While research has long focused on screen time as the culprit for poor sleep, growing evidence suggests that how often people check social media − and how emotionally engaged they are − matters even more than how long they spend online.
And one of the most common yet underestimated factors shaping modern sleep? How we engage with social media before bed.
Emotional investment in social media
Beyond simply measuring time spent on social media, researchers have started looking at how emotionally connected people feel to their social media use.
Some studies suggest that the way people emotionally engage with social media may have a greater impact on sleep quality than the total time they spend online.
In a 2024 study of 830 young adults, my colleagues and I examined how different types of social media engagement predicted sleep problems. We found that frequent social media visits and emotional investment were stronger predictors of poor sleep than total screen time. Additionally, presleep cognitive arousal and social comparison played a key role in linking social media engagement to sleep disruption, suggesting that social media’s effects on sleep extend beyond simple screen exposure.
I believe these findings suggest that cutting screen time alone may not be enough − reducing how often people check social media and how emotionally connected they feel to it may be more effective in promoting healthier sleep habits.
How social media disrupts sleep
If you’ve ever struggled to fall asleep after scrolling through social media, it’s not just the screen keeping you awake. While blue light can delay melatonin production, my team’s research and that of others suggests that the way people interact with social media may play an even bigger role in sleep disruption.
Here are some of the biggest ways social media interferes with your sleep:
Presleep arousal:Doomscrolling and emotionally charged content on social media keeps your brain in a state of heightened alertness, making it harder to relax and fall asleep. Whether it’s political debates, distressing news or even exciting personal updates, emotionally stimulating content can trigger increased cognitive and physiological arousal that delays sleep onset.
Habitual checking:Social media use after lights out is a strong predictor of poor sleep, as checking notifications and scrolling before bed can quickly become an automatic habit. Studies have shown that nighttime-specific social media use, especially after lights are out, is linked to shorter sleep duration, later bedtimes and lower sleep quality. This pattern reflects bedtime procrastination, where people delay sleep despite knowing it would be better for their health and well-being.
Fear of missing out, or FOMO: The urge to stay connected also keeps many people scrolling long past their intended bedtime, making sleep feel secondary to staying updated. Research shows that higher FOMO levels are linked to more frequent nighttime social media use and poorer sleep quality. The anticipation of new messages, posts or updates can create a sense of social pressure to stay online and reinforce the habit of delaying sleep.
Taken together, these factors make social media more than just a passive distraction − it becomes an active barrier to restful sleep. In other words, that late-night scroll isn’t harmless − it’s quietly rewiring your sleep and well-being.
How to use social media without sleep disruption
You don’t need to quit social media, but restructuring how you engage with it at night could help. Research suggests that small behavioral changes to your bedtime routine can make a significant difference in sleep quality. I suggest trying these practical, evidence-backed strategies for improving your sleep:
Give your brain time to wind down: Avoid emotionally charged content 30 to 60 minutes before bed to help your mind relax and prepare for sleep.
Create separation between social media and sleep: Set your phone to “Do Not Disturb” or leave it outside the bedroom to avoid the temptation of late-night checking.
Reduce mindless scrolling: If you catch yourself endlessly refreshing, take a small, mindful pause and ask yourself: “Do I actually want to be on this app right now?”
A brief moment of awareness can help break the habit loop.
Boredom is a common part of life, across time and around the world. That’s because boredom serves a useful purpose: It motivates people to pursue new goals and challenges.
I’m a professor who studies communication and culture. I am currently writing a book about modern parenting, and I’ve noticed that many parents try to help their kids avoid boredom. They might see it as a negative emotion that they don’t want their children to experience. Or they might steer them into doing something that they see as more productive.
There are various reasons they want to prevent their children from being bored. Many parents are busy with work. They’re stressed about money, child care responsibilities and managing other parts of daily life. Making sure a child is occupied with a game, a TV show or an arts and crafts project at home can help parents work uninterrupted, or make dinner, without their children complaining that they are bored.
Parents may also feel pressure for their children to succeed, whether that means getting admitted to a selective school, or becoming a good athlete or an accomplished musician.
Children also spend less time playing freely outside and more time participating in structured activities than they did a few decades ago.
Easy access to screens has made it possible to avoid boredom more than ever before.
That is to say, there are various reasons why parents shy away from their kids being bored. But before striving to eliminate boredom completely, it’s important to know the benefits of boredom.
Although boredom feels bad to experience in the moment, it offers real benefits for personal growth.
Boredom is a signal that a change is needed, whether it be a change in scenery, activity or company. Psychologists have found that the experience of boredom can lead to discovering new goals and trying new activities.
Harvard public and nonprofit leadership professor Arthur Brooks has found that boredom is necessary for reflection. Downtime leaves room to ask the big questions in life and find meaning.
Children who are rarely bored could become adults who cannot cope with boredom. Boredom also offers a brain boost that can cultivate a child’s innate curiosity and creativity.
Learning to manage boredom and other negative emotions is an important life skill. When children manage their own time, it can help them develop executive function, which includes the ability to set goals and make plans.
Parents should be wary of treating boredom as a problem they must solve for their children. Psychologists have found that college students with overly involved parents suffer from more depression.
Other research shows that young children who were given screens to help them calm down were less equipped to regulate their emotions as they got older.
Boredom is uncomfortable
Tolerating boredom is a skill that many children resist learning or do not have the opportunity to develop. Even many adults would rather shock themselves with electricity than experience boredom.
It takes practice to learn how to handle boredom. Start with small doses of boredom and work up to longer stretches of unstructured time. Tips for parents include getting kids outside, suggesting a new game or recipe, or simply resting. Creating space for boredom means that there will be some stretches of time when nothing in particular is happening.
Encouraging older children to solve the problem of boredom themselves is especially empowering. Let them know that boredom is a normal part of life even though it might feel unpleasant.
Letting go of the obligation to keep children entertained could also help parents feel less stressed. Approximately 41% of parents in the U.S. said they “are so stressed they cannot function,” and 48% reported that “most days their stress is completely overwhelming,” according to a report from the U.S. surgeon general in 2024.
So the next time a kid complains, “I’m bored!” don’t feel guilty or frustrated. Boredom is a healthy part of life. It prompts us to be self-directed, find new hobbies and take on new challenges.
Let children know that a little boredom isn’t just OK – in fact, it’s good for them.
Brenda and Brian Marquis are part of a growing senior population with mental and physical ailments. In particular, Brian has dementia from a brain injury he sustained in 2012. Brenda would help Brian remember to wash himself, eat lunch, and other tasks. On top of that, both live with other physical, cognitive, and emotional disabilities that make day-to-day living difficult. Then came “Robbie.”
“Robbie” is the robot that helps the Marquis family with their daily routines at home. Resembling a coat rack, the robot was presented to the Marquis family after Brenda sent an email to the University of New Hampshire inquiring about robotic service dogs. Booker T. Bones, the family’s service dog, had passed away and Brenda was looking for similar support. The university saw this as an opportunity for its computer science center to experiment with “socially assistive” robots.
This Home Robot Actually Works! This robot might beat humanoids to the home. Hello Robot’s Stretch 4 is a wheeled robot with an arm, built to move safely, reach objects, and help with real daily tasks. It may not look like a sci-fi butler, but practical robots like this could arrive first. Would you trust a robot like this in your home?

“Our goal is not to replace a human caregiver but to use technology such as robots to provide complementary care,” Sajay Arthanat, a professor in UNH’s Department of Occupational Therapy told WMUR. “We know that caregivers often have to perform a lot of repetitive, mundane tasks.”
What exactly is “Robbie”?
“Robbie” is a Stretch 4 robot model invented by Hello Robot. While a very simple in design, the robot is able to help Brian with a number of tasks. It reminds him to eat meals at specific times, fetches items such as water bottles out of the fridge, reads the fine print of prescription medications, and more. Stretch 4 also has prompts that activate when he enters certain rooms of the home, such as the bathroom.
“I was never into technology,” Brian Marquis said to Sentinel Colorado. “Then I realized I can’t remember to wash my face and my armpits. So, it just really kind of set me free almost.”
Robbie hasn’t just helped Brian live more independently, but Brenda as well. She doesn’t have to be by Brian’s side 24/7. Now, she can go out and play mahjong with her friends without worrying about leaving Brian alone for several hours.
I saw this in South Korea. This is Robocare, two companion robots for eldercare. This robots to help prevent elderly people’s dementia by providing game content to improve brain power. The robot, via positioning system, monitors elderly people’s walking paces in real-time and is integrated with smartwatches and wrist bands to analyze users’ sleeping and daily activities.

Per the Department of Health and Human Services, the majority of older adults are projected to need long-term care and service. This could range from basic needs to extreme health cases. In addition, a 2025 report released by the Bureau of Labor Statistics found that 38.2 million people provided unpaid elder care. Around 28% of those people provided nearly four hours of unpaid elder care per day.
The number of people who need such help is projected to grow exponentially. By 2030, the number of Americans over 65 is expected to surpass the number under 18 for the first time in U.S. history. The number of Americans over 65 years old is projected to reach 82 million, a 40% growth from 2022.
This is, in part, why there has been such massive investment in robots and A.I. specializing in caring for elderly people. It’s not just to ensure that the elderly have the assistance they need for day-to-day tasks. Eldercare robots also boost their patient’s confidence by allowing them to live as safely and independently as they can. In addition to task-oriented robots like Stretch 4, there are also robots to assist with mobility.
Robotics are helping improve the lives of the elderly as a new and exciting care option. With the help of medication, personal care from a human, community, and more, the growing elderly population can thrive through their golden years.

Whether through use of a robot or not, finding solutions to aid and care for our older populations ultimately benefits society as a whole.
