Your brain physically changes when you work too much, scientists warn
NEWYou can now listen to Fox News articles!
New research has found that being overworked can physically alter the brain.
Researchers in South Korea set out to understand how working long hours impact the cognitive and emotional health of employees.
The study, published in the journal Occupational & Environmental Medicine, assessed the brain volume of 110 healthcare workers who were classified by the categories of overworked – working greater than or equal to 52 hours per week – and non-overworked.

The results revealed that overworked individuals exhibited “significant changes” in brain regions that are associated with executive function and emotional regulation.
Study co-author Wanhyung Lee, M.D., Ph.D., assistant professor at Chung-Ang University College of Medicine in Seoul, told Fox News Digital that this is one of the first studies to examine the relationship between prolonged working hours and structural brain changes.

“We initially had no clear expectations regarding what we might discover,” he revealed. “Therefore, we found the results particularly intriguing.”
The researcher noted that increased brain volume associated with cognitive and emotional functions was an “unexpected and fascinating” observation of the study.
“These findings open new questions and underscore the complexity of how chronic occupational stress might affect brain health, highlighting the need for further detailed investigations,” he said.

The increased brain volume as observed was found in regions associated with executive functions, Lee said, such as memory, decision-making and attention — as well as emotional regulation, such as stress management and emotional stability.
While these changes may initially reflect a need to manage “ongoing occupational stress,” according to Lee, there could be potential risks of prolonged or chronic alterations.
This could include neural strain, inflammation or maladaptive reorganization.

“Although our current study cannot conclusively determine the long-term impacts, ongoing exposure without sufficient recovery may negatively affect cognitive and emotional health,” he said.
Lee urged employees who work excessive hours to recognize that chronic stress can lead to physical brain changes, not just psychological complications. This emphasizes the need to manage workload, prioritize rest and maintain emotional balance.
“At the same time, individual efforts alone are not sufficient; organizational support and proactive management by companies to create healthy working conditions are essential to protect employees’ brain health,” he said.

“With the rapid advancement of smartphones and digital technology, work increasingly extends beyond traditional office hours into personal time, making chronic overwork more common and less visible,” Lee went on. “Employers and policymakers must also acknowledge and address these evolving work patterns to support sustainable working environments.”
The researcher recognized the progressive move toward becoming an “overwork society.” He urged employees to “actively set boundaries, ensure regular rest and recovery, practice stress management, and advocate for workplace policies that clearly define and respect healthy work-hour limits.”

Dr. Paul Saphier, a neurosurgeon and founder of Coaxial Neurosurgical Specialists in New Jersey, was not involved in the study but commented on the findings in an interview with Fox News Digital.
Saphier considered the study interesting, yet not “overly surprising.”

“There is no question that mental stress and fatigue, either with sleep deprivation, anxiety, long periods of intense concentration, etc., lead to alteration of neurotransmitter release and additional physiological changes,” he said. “This may ultimately lead to anatomical changes within the brain.”
Experts have known that professions that require “crisp cognitive awareness” with “zero room for error” — such as airline pilots and medical professionals — benefit from “limited consecutive work hours to reduce errors,” said the neurosurgeon.
“Caring for your mental health and well-being is essential if you want to be a productive employee,” one career expert said. (iStock)
Kyle Elliott, a California-based tech career coach and mental health expert, also weighed in during a separate interview with Fox News Digital.
“Caring for your mental health and well-being is essential if you want to be a productive employee,” he said.
“Neglecting your mental health can not only affect your ability to work effectively but also negatively impact your physical health and longevity.”

Elliot encouraged employees to advocate for their needs.
“Don’t be afraid to speak up [at work or to employers] if you need to take a break or time off to protect your mental or physical health,” he said. “Your mind and body will thank you in the long run.”
The expert suggested taking smaller steps to preserve mental health and prevent burnout, such as taking allocated breaks throughout the workday, connecting with people who are safe to share your frustration with and limiting time on social media.

One walking habit could signal a healthier brain after 80, scientists say
NEWYou can now listen to Fox News articles!
Older adults identified as “super movers” are about half as likely to develop cognitive impairment than their peers.
That’s according to a recent study led by Stony Brook Medicine in New York, which evaluated the cognitive function of 4,000 adults 80 and over who participated in multiple aging and longevity studies over several years.
Among this group, 6% to 10% were classified as super movers, which means they walk at a much faster pace than others of the same age and gender — at speeds comparable to people three decades younger.
COMMON VITAMIN MAY INFLUENCE BRAIN AGING IN WAYS SCIENTISTS DIDN’T EXPECT
The super movers were found to have about half the risk of cognitive decline compared to seniors with typical gait speed.
The findings were published in the journal Neurology on June 16.

“The study reinforces that mobility and brain health are closely connected,” lead study author Dr. Joe Verghese, MD, neurologist at Stony Brook Medicine, told Fox News Digital. “This suggests that preserving mobility may be an important marker of healthy brain aging and resilience.”
‘LONGEVITY GENE’ MAY PROTECT THE BRAIN FROM ALZHEIMER’S BY BOOSTING DNA REPAIR, STUDY FINDS
The most intriguing finding, according to Verghese, was that super movers maintained cognitive function despite having similar dementia-related brain changes as their peers.
In postmortem brain analysis, there was no difference in dementia-related pathologies between the super movers and the slower walkers, the study stated.

“This suggests they may possess resilience mechanisms that help preserve brain function even in the presence of age-related changes,” he said. “Understanding these resilience factors could lead to new strategies for promoting healthy brain aging.”
As the study was observational, there were some limitations, and it does not prove that walking faster prevents dementia, the researchers noted.

“Other factors, such as cardiovascular health, physical fitness or genetics, may also contribute to both faster walking and better cognitive outcomes,” Verghese said.

This study adds to growing evidence that what’s good for the heart and muscles also benefits the brain, he noted, adding that “staying physically active remains one of the most effective, evidence-based ways to support healthy aging.”
“Walking speed is best viewed as a marker of overall health, not a treatment.”
“The broader message is that physical activity is important at any age,” Verghese said. “Walking is an easy step-up point because you don’t need any special equipment. You can do it inside or outdoors, and you can do it on a regular basis. You can walk with a dog, you can walk with a friend.”
Any activity is beneficial if it’s done regularly and with the right intensity, he added.

Rather than just trying to walk faster, the neurologist recommends that seniors focus on maintaining mobility through regular physical activity, strength training, balance exercises and good cardiovascular health.
“Walking speed is best viewed as a marker of overall health, not a treatment,” Verghese noted.
Major public health guidelines from the CDC and U.S. Physical Activity Guidelines recommend at least 150 minutes of moderate-intensity aerobic activity each week, such as brisk walking.

This can be achieved by walking 30 minutes a day, five days a week, or about 20 to 25 minutes most days. Another option is to engage in shorter sessions that add up over the day.

“You have to do it within your health limitations and medical conditions,” Verghese advised. “So if there are any medical concerns, I would get your physician to clear you before starting exercise.” The good thing about walking, he added, is that you can start at a slow pace and then gradually build up to a brisker pace.
“And then adding on strength and balance training, whatever age you are, I think is also important.”

Dr Oz warns Medicare scammers are stealing billions — and your personal information could be next
NEWYou can now listen to Fox News articles!
Washington, D.C. – Medicare fraud is a multibillion-dollar problem that government officials say threatens both taxpayer dollars and Americans’ personal identities.
In a July 6 interview with Fox News Digital at the Great American State Fair in Washington, D.C., Dr. Mehmet Oz warned that every dollar stolen through Medicare fraud is a dollar taxpayers lose – a problem that has worsened since the COVID pandemic.
“If I had to just pick one thing to focus on to make healthcare more affordable in America, I’d go to health fraud and all the waste and abuse that accompanies it,” said Oz, who is the administrator of the Centers for Medicare & Medicaid Services. “And just to put this in perspective, we think it’s about $100 billion a year.”

Medicare fraud can include billing for services that were never provided, overcharging for medical equipment, using stolen patient or doctor information, or performing unnecessary procedures, according to the U.S. Government Accountability Office.

As the Trump administration ramped up efforts to combat fraud, CMS reported $41.9 billion in Medicare program integrity savings in 2025, up 59% from $26.3 billion in 2024.

Medicare fraud not only harms the federal budget and steals from taxpayers, but exposes seniors to identity theft, unnecessary care, higher premiums and reduced access, Oz cautioned.

Removing corruption from the healthcare system will have the greatest impact among seniors, since “so much of the fraud is perpetrated against them,” the administrator said.
“I’m talking about people tricking seniors to give up their Medicare beneficiary numbers, which is like a credit card basically,” he said. “These scammers can take those numbers and use them for all kinds of illegitimate purposes.”

“People are stealing from you by pretending to send you drugs you don’t want, wheelchairs you don’t need, [and] services you never asked for or don’t benefit from,” Oz added.
To prevent this, he shared his top advice for seniors: Do not give your Medicare beneficiary number to anybody, do not answer questions on a phone call from an unknown person and do not give away personal information.

“These scammers are calling seniors, tricking them, and once they have key information, they can steal it,” he said. “And I won’t know it and you won’t know it.”
“We want to protect people who need these programs the most,” Oz went on. “You do that by making sure scoundrels don’t corrupt the systems and steal money out of the till that is designed to help folks in dire straits when they’re vulnerable and in need of services.”
Seniors should never share their Medicare information with unknown people, the administrator advised. (iStock)
Removing fraud could “double the life expectancy of the trust fund that makes all this possible,” Oz predicted.
“If you’re worried about Medicare being there when you’re ready to retire in a couple decades, depending on how old you are, and you’re concerned that it might not last because of all the fraud that’s hitting it … you’ve got a good [reason to] worry,” he said.
