COVID pandemic restrictions had 'alarming' impact on teenagers’ brains, new study finds
The pandemic’s negative effects on kids and teens — academically, socially and otherwise — have been shown in numerous studies, and now the latest long-term effect appears to be accelerated aging of young brains.
A team of researchers at the University of Washington studied 160 teens between the ages of 9 and 17. They had gathered data in 2018 for a different study on changes in brain structure during adolescence, but the COVID pandemic interrupted that research.
“Once the pandemic was underway, we started to think about which brain measures would allow us to estimate what the pandemic lockdown had done to the brain,” lead author Neva Corrigan, Ph.D., a research scientist at the University of Washington, said in a press release.

“What did it mean for our teens to be at home rather than in their social groups — not at school, not playing sports, not hanging out?”
The researchers found that the pandemic caused teenage brains to age faster than normal.

“The lifestyle changes due to the COVID-19 pandemic lockdowns appear to have affected brain development during adolescence, causing the brain to mature much faster than is typical,” Corrigan told Fox News Digital via email.
“This accelerated maturation was more widespread throughout the brain, and larger in magnitude, for females as compared to males.”

On average, the young females’ brains aged 4.2 years faster than normal, and male brains were accelerated by 1.4 years.
Thirty regions in the female brain showed accelerated aging, compared to only two regions in the male brain, researchers found.
The findings were published in the Proceedings of the National Academy of Sciences on Sept. 9.

The researchers believe that the accelerated brain aging was due to the stress associated with the restrictive measures taken to curb COVID’s spread, Corrigan said.
“Accelerated development of the cerebral cortex during development has been well-established by previous research to be associated with chronic stress,” she noted.
Recommendations to parents
This study highlights the fact that teenagers’ brains are highly vulnerable to stressors in their environment, according to Corrigan.
“We recommend that parents of children who were teens during the pandemic stay connected to their teens, and also look out for signs of depression and anxiety, as accelerated cortical thinning increases the risk of developing these and other neuropsychiatric disorders,” she advised.

“We also think parents should be aware that their teens’ social lives are very important to their brain development, and [they should] encourage healthy activities with peers.”
While these findings “seem alarming,” Corrigan said, it’s not known whether the accelerated aging will have long-term effects on continued brain development throughout the teens’ lives.
“It is not clear whether the cerebral cortex of these teens that showed accelerated maturation will return to a thickness that is more appropriate for their age with time, or whether these effects are permanent,” she told Fox News Digital.

She also pointed out that “cortical thinning” is a natural process in aging and can actually allow the brain to function more efficiently.
“It is not clear that all the consequences of accelerated maturation are negative,” Corrigan added.
Potential limitations
The researchers acknowledged several limitations of the study, the first being its smaller sample size.
“Although we collected data from 160 teens prior to the lockdowns, and 130 teens after the lockdowns ended, larger samples are always better when conducting research,” Corrigan told Fox News Digital.
“What did it mean for our teens to be at home rather than in their social groups — not at school, not playing sports, not hanging out?”
“Also, since the study was not initially designed for the effects of the COVID pandemic, we did not collect the type of behavioral measures that would have allowed us to determine what exact lifestyle disruptions or stressors associated with the lockdowns might have been the greatest contributors to the stress experienced by the teens,” she said.
The researchers also only studied a limited age range, so they couldn’t determine whether the findings apply to other ages.

“Finally, we do not know whether contraction of the COVID-19 virus itself may have contributed to these findings, although in the community from which our study sample was derived, we found no reports of a sex disparity in the contraction of the virus,” Corrigan said.
‘Downrange effects’
Dr. Brett Osborn, a Florida neurologist, was not involved in the study, but commented on the “detrimental consequences” of pandemic-related stress for teens.
“We recommend that parents of children who were teens during the pandemic stay connected to their teens, and also look out for signs of depression and anxiety,” a researcher said. (iStock)
“High levels of stress, often associated with elevated cortisol, can wreak havoc on the brain,” he told Fox News Digital.
Cortisol, the body’s primary stress hormone, is typically released by the adrenal glands during acute stress, Osborn explained, but it can become harmful when present at high levels for prolonged periods.

“This chronic elevation is particularly damaging to brain structures like the hippocampus (the region associated with memory) and the prefrontal cortex, which is responsible for higher-level cognitive functions like decision-making and social behavior.”
“While the pandemic is over, this is not the end.”
Long-term exposure to high cortisol levels can negatively impact memory, emotional regulation, impulse control, focus and concentration, according to Osborn.
“Over time, these changes may predispose individuals to mental health disorders such as depression and anxiety, which are already known to be exacerbated by high cortisol levels,” he added.

Overall, Osborn said, the study sheds light on “yet another downrange effect” of the COVID-19 pandemic.
The doctor added, “While the pandemic is over, this is not the end.”

Bryan Johnson, a biohacker and longevity guru who has claimed “we may be the first generation who won’t die,” revealed he has an autoimmune condition causing his stomach to “eat itself.”
The Los Angeles-based tech entrepreneur, 48, has previously shared publicly that he is hoping to live until the year 2140, when he would in theory be 160 years old.
Now, Johnson says he has been diagnosed with autoimmune gastritis (AIG), a chronic autoimmune disease in which the immune system attacks the stomach’s acid-producing parietal cells, reducing stomach acid and impairing vitamin B12 absorption, according to Nature Reviews Disease Primers.

“My stomach is eating itself,” he wrote in an Instagram post. Johnson also shared that anywhere from 2% to 5% of people likely have this disease.
“I’m going to try to solve it,” Johnson went on. “Will share all.”

The biohacker shared that as a child, he ate sugary cereal, drank sugary soda and “gobbled down fast food.”
“I became a young father of three and began building a business,” Johnson went on. “Juggling that stress and grind, I let my health slip and gained 40 lbs. Within a few years I’d fallen into a deep, chronic depression.”
DOCTORS SAY 8 FORGOTTEN HABITS COULD HELP FIGHT STRESS, OBESITY AND CHRONIC DISEASE
“Somewhere in that timeline, my body began developing an autoimmune process affecting my thyroid and then my stomach lining,” he added.
Fox News Digital reached out to Johnson for comment.
AIG can remain hidden and can be challenging to diagnose, Johnson noted, often surfacing years after damage has already occurred to the stomach. It can cause iron deficiency, B12 deficiency and anemia, and can also increase the risk of stomach cancer, the expert warned.
“Low iron stores get normalized and rarely investigated at all when anemia hasn’t shown up yet,” Johnson wrote. “That blind spot is what hid mine for a decade.”

He also shared that for 11 years, he has had low levels of ferritin, a protein that stores iron inside the body’s cells. Ferritin releases iron when the body needs it, supports muscle function and carries out other essential processes.
“We continually tried to raise my iron levels with food and supplementation, but nothing would work,” he said.

Johnson acknowledged that some common biohacking techniques — including hard training, sauna and hyperbaric oxygen — all raise the body’s demand for iron.
“But none of them explained the core failure: Despite me taking iron orally, trailing every formulation and using every timing trick, none of the iron would stick.”

Johnson underwent a colonoscopy and upper endoscopy, which examined his entire intestinal tract. Five biopsies were also taken from his stomach, which found “clear signs of early autoimmune gastritis: early atrophy confined to the acid-producing lining.”
In January 2026, the biohacker stated in a post on his website that “by 2039, my goal is immortality.”
“In the age of AI, multiomics, and custom-built DNA, proteins and cells, no condition should be presumed incurable simply because no one has yet tried to cure it with today’s stack,” Johnson said in his post. (Getty Images)
He detailed his strategy for defying aging, which includes embracing a strict regimen to slow or stop biological aging, using AI to accelerate longevity research, testing new treatments in lab-grown cells and organs, and reaching “longevity escape velocity” — in which medical advances would eventually extend lifespan faster than he ages.

“I may fail at this task, but my team and I will try our best,” he wrote at the time.
There is currently no cure for AIG, which Johnson said he wants to change.

At 93, sprightly referee Frank Foster is still brandishing red and yellow cards and running the field three times a week for his local soccer association.
Having taken charge of around 5,500 matches over a 46-year officiating career, the great-grandfather credits his longevity and match-day stamina to a lifetime of healthy habits and a foundational diet, news agency SWNS reported.
Foster puts his remarkable fitness down to the strict wartime rations he was fed as a teenager, noting that it ensured he grew up eating “healthy food” rather than “sweets and cakes.”
FITNESS EXPERT REVEALS 6 PILLARS OF STRENGTH TRAINING THAT OLDER ADULTS SHOULD MASTER
Decades later, his game-day preparation is still fueled by wholesome nutrition, always starting with a morning bowl of oatmeal, cereal or marmalade on toast to give him the energy to last the full 90 minutes.
The meal keeps him active enough to referee men’s, women’s and children’s games, a hobby he jokes he will never blow the final whistle on.

His sharp mind and authoritative presence on the field are just as strong as his physical endurance.
A military veteran who aced his referee exam in 1980 with a 98% score, Foster relies on old-school discipline to keep matches under control, SWNS reported.
7 COMMON FITNESS MISTAKES OLDER ADULTS MAKE AND HOW TO AVOID THEM FOR BETTER WORKOUTS
He believes modern elite officials are too “soft” and allow player antics to ruin the sport. To maintain order and keep players from acting out, he lays down strict ground rules before kickoff. He has no patience for intimidation or theatrical diving. “Those who go down like they have been shot, well, I would just book them,” he said.
He is equally uncompromising when squads try to crowd him on the field.

“I wouldn’t let them surround me at all,” Foster told SWNS.

“I would say to the players, ‘Stay where you are,’ and ‘If you move one more inch, I will give you a yellow card.’ You need to stamp your authority and let them know who is in control.”

Foster says he “never thought” he’d still be doing this at age 93, but he makes the most of that gift.
He keeps his kit freshly washed, making sure it is “neat and tidy” for when he gets on that field.

Summer fun in the sun is being taken to a new extreme.
“Tanmaxxing” is a social media trend that involves maximizing sun exposure and tanning the skin more intensely.
Popular among Gen Z, the practice combines time spent in direct sunlight with a variety of tanning products like oils, bronzers and gels.
POPULAR FRUIT MAY HELP PROTECT YOUR SKIN FROM THE SUN, NEW STUDY SUGGESTS
Creators on social media are showing off their dramatic tan lines and outdoor set-ups — some even forgoing sun protection or adding tanning bed sessions.

While spending time outdoors can help boost mood, support the body’s production of vitamin D and reduce screen time, dermatologists warn that excessive sun exposure — especially as promoted by the tanmaxxing trend — can be dangerous.
New York-based board-certified dermatologist Dr. Michael Tassavor, MD, emphasized that there is “no such thing as a safe, natural tan.”

“Tanning is damage,” he said in an interview with Fox News Digital. “Tanfluencers sell a deep tan as a ‘wellness upgrade,’ but a tan isn’t a glow-up — it’s your skin’s visible distress signal that DNA damage has already happened.”
“As a skin cancer specialist, I’ve taken care of thousands of skin cancers on patients who ‘tanmaxxed’ before it had a name. Most regret it.”
Using a tanning bed before 35 years old can raise melanoma risk by about 75%, an expert warned. (iStock)
The World Health Organization classifies UV radiation and tanning beds as Group 1 carcinogens, which is the same category as tobacco and asbestos.
Using a tanning bed before age 35 can raise melanoma risk by about 75%, Tassavor noted.

“The damage compounds silently and shows up years later, once the easy window to intervene has closed,” he said.
According to Tassavor, two common beliefs behind tanmaxxing are false: Skipping sunscreen does not produce a “better” tan, and a base tan does not protect the skin from future sunburns.
“Most of your vitamin D can come from diet and supplements, and your skin is efficient enough to top up what it needs from ordinary incidental exposure,” a dermatologist said. (iStock)
Sunlight “isn’t the enemy,” the dermatologist noted, but there’s no need to chase it.
“Most of your vitamin D can come from diet and supplements, and your skin is efficient enough to [get] what it needs from ordinary incidental exposure,” he said.

“Vitamin D matters for bone density, and sun does give some people a genuine mood lift, but there’s no evidence that anyone has to go out of their way to sunbathe for it, and no evidence that diligent sunscreen use harms bone health.”

To safely expose yourself to the sun, Tassavor recommends using SPF 30 sunscreen and reapplying every two hours. Tanning beds should be avoided “entirely,” he cautioned, because there is “no safe dose” of UV exposure and using them accelerates skin aging.
