What is ‘brain rot’? The science behind what too much scrolling does to our brains
Oxford University Press has chosen “brain rot” as its word of the year.
The word is defined as “supposed deterioration of a person’s mental or intellectual state, especially viewed as a result of overconsumption of material (now particularly online content) considered to be trivial or unchallenging. Also: something characterized as likely to lead to such deterioration.”
Some experts believe that constant, endless scrolling of social media and other online content is doing exactly that – rotting our brains.

Behavioral neuroscientist Dr. Kyra Bobinet, author of “Unstoppable Brain,” told Fox News Digital that there is a growing awareness of brain rot and its consequences.

“It’s in the zeitgeist that people have difficulty with their attention span. They feel brain foggy, they [have] less concentration … They can’t do deep work,” said California-based Bobinet.
“And then there’s also this epidemic of loneliness that has been kind of sitting on the heels of this, because we can’t really focus on anything, including relationship-building.”
Stuck in a scroll
A certain part of the brain, called the habenula, is responsible for getting stuck in endless scrolling, according to Bobinet.
The habenula is a central part of the brain that’s involved in various important functions, including motivation and decision-making. But when activated, this area can also “kill our motivation to try,” she noted.

“It’s the heart of when you know you should be doing something, and you do this other thing instead, like ‘doom-scrolling,’” she said.
“This is the area of our brain that when it’s on, we feel depressed. We feel out of control, we feel impulsive, we feel addicted,” one neurologist said about the habenula. (iStock)
Scrolling on social media is also a way to “disassociate” and give the brain a rest after a long day, Bobinet said. This is an “avoidance behavior,” which the habenula controls.

“Anytime you’re avoiding something, you know this area of the brain is on,” she said.
This is how social media addictions can form, Bobinet warned, as this part of the brain can make it “very painful” to stop scrolling.
“There’s this epidemic of loneliness that has been kind of sitting on the heels of this, because we can’t really focus on anything, including relationship-building,” one expert said. (iStock)
This can result in a “dangerous” loss of motivation, the neuroscientist warned.
“We all need motivation to live our lives and to feel proud of ourselves and to feel confident and to get what we want,” she told Fox News Digital.
How to avoid brain rot
There isn’t a one-size-fits-all solution for avoiding brain rot, according to Bobinet.
The key is learning what works best for the individual, she said, which involves “tweaking and tinkering and adjusting as you go,” she said.
“Humans are very resilient,” she added. “Once we know the truth about our bodies, then we can do something about it.”

Dr. Don Grant, national adviser of healthy device management at Newport Healthcare in Los Angeles, called out device makers and content producers for keeping users hooked to their devices.
“They’re very clever, these creators who created these algorithms and also leverage our limbic system – the same [way] the people who created slot machines did,” he told Fox News Digital. “Pull the handle … You never know what you’re going to get.”
‘BED ROTTING’ IS SELF-CARE, SOME INSIST, BUT MENTAL HEALTH EXPERT SHARES WARNINGS ABOUT SOCIAL MEDIA TREND
Grant said he’s concerned about “the death of some things,” including imagination.
“We don’t have to imagine anything anymore,” he said. “We pick up our devices every time. I’m worried about memory. I’m worried about education.”
Grant said he often hears from kids that they spend eight hours on any given night scrolling and watching videos, which “disrupts their sleep hygiene.”

“And I say, ‘OK, can you tell me one video you remember?’ I have yet to have one kid really be able to remember anything they saw.”
“Our brain matter is diminishing, our memories are diminishing [and] our attention spans are diminishing,” Grant warned.
“I’m worried about memory. I’m worried about education.”
The expert offered some tips to avoid getting stuck in a “doom scroll” of “endless, bottomless” content, especially for children.
Since the internet is “archived forever,” Grant noted that “FOMO,” or fear of missing out, is not a valid reason to stay online.

“Maybe phone a friend or FaceTime your grandma for the holidays,” he suggested.
Grant also urges people to be more strategic about spending time online, splitting it up into 80% “meaningful, legitimate” content and 20% entertainment.

“For digital hygiene and well-being, you can set limits, you can block access,” said Grant. “Set tech-free times and zones in your home, especially for families.”
“Get outside, move a muscle … play memory games, intellectually challenging or educational games.”

The expert also encourages people to ask themselves a few questions after scrolling to help gauge the quality of time spent.
These might include: “Could you tell me how much time you were online? Did you spend more time than you wanted to? Did you feel better?”
Grant added, “There’s a perceived danger of virtual life and how we’re using our free time – at the end of it, are you really feeling good about yourself?”

After a season of bingeing and drinking, your body may feel like it needs a break from the party.
Dry January — a modern trend that challenges people to abstain from drinking for the first month of the year — has become a popular way to “detox” from the holidays and start the new year on a healthy note.
Research has linked alcohol to a variety of health conditions, ranging from hangovers to higher cancer risk.
5 POPULAR HANGOVER MYTHS THAT DON’T WORK AFTER HOLIDAY DRINKING, ACCORDING TO EXPERTS
In a recent podcast episode of “The Dr. Mark Hyman Show,” Dr. Mark Hyman, chief medical officer of Function Health, shared how 30 days of not drinking alcohol can transform health.
Hyman, who is based in Massachusetts, called Dry January a “powerful way to see in real time how alcohol affects nearly every system of your body and how quickly those systems can recover.”

Alcohol’s toll on the brain and body
Hyman acknowledged that most people drink to feel happier and more comfortable in social situations. This effect is caused by the main ingredient in alcohol, called ethanol, which can also have toxic effects.
Instead of stimulating the brain, alcohol slows it down and loosens inhibitions. “You feel more relaxed, more social, more confident, maybe you feel a little euphoric,” Hyman said.
Alcohol’s effect on the brain can also lead to poorer decisions and slower reflexes, the doctor cautioned.
Drinking alcohol can cause cognitive decline and brain fog, experts warn. (iStock)
Drinking also impacts the prefrontal cortex of the brain, which Hyman described as “the adult in the room,” responsible for judgment, planning and restraint. “It goes offline early in drinking, which explains why people feel freer or act impulsively when they drink,” he said.
Even moderate drinking can cause metabolic stress, inflammation, impaired detoxification and hormonal shifts, Hyman said, which can impact nearly every organ system in the body.

Alcohol consumption has also been linked to an increased risk of cancer, metabolic dysfunction, gut microbiome disturbances and mitochondrial toxins.
It can also prevent the body from falling into REM sleep, which is the deep rest recovery period when the immune system cleans out the day’s toxins, according to Hyman.

Memory loss, cognitive decline, anxiety, sleep disruption, dementia and cardiovascular disease are all known risks of long-term alcohol use, as well as liver complications like fatty liver disease.
“Bottom line, alcohol taxes every major system in your body, especially your liver, your brain, your gut, your hormones,” Hyman said.
The effects of 30 days with no alcohol
The first week after your last drink, the body begins to detoxify and reset, according to Hyman. Blood sugar and cortisol stress hormones level out, and the liver begins to process a “backlog of toxins.” The body also re-hydrates and re-energizes.

The second week, the gut and brain will begin to re-balance, as hormones like serotonin and dopamine stabilize, gut inflammation drops and the microbiome begins to heal. Cravings for sugar and alcohol will wane and mental clarity returns, the doctor said.
Week three is marked by further decreases in inflammation, fatty liver and blood pressure. This can be noticeable in the skin, as puffiness and redness are reduced. Mood also begins to stabilize, with lower anxiety levels.
DOCTORS REVEAL WHY ALCOHOL CAUSES ‘BOOZE BUTT’ AND HOW TO PREVENT IT ON NEW YEAR’S
In week four, the body experiences additional metabolic and immune benefits, Hyman shared, including more insulin sensitivity, which makes it easier to lose weight.
“You have a stronger immune response. You’re not getting sick as much. You have better deep sleep, balanced hormones, especially cortisol and testosterone,” he said. “And you see a big change in energy, confidence and focus.”

Dr. Pinchieh Chiang, a clinician at Circle Medical in San Francisco, said that Dry January isn’t a “detox,” but rather provides “feedback” from the body.
“It gives the body time to show people how it feels without alcohol. For many, that insight alone changes their relationship with drinking,” she said. “The biggest surprise isn’t what people give up, it’s how much better they feel.”
HIGHER STROKE RISK LINKED TO CONSUMING CERTAIN AMOUNT OF ALCOHOL, STUDY FINDS
The doctor confirmed that the first few days of not drinking may feel harder than expected, sometimes causing restlessness, cravings or disrupted sleep, but Dry January can ultimately change drinking habits for the remainder of the year.

After a full year without alcohol, Chiang noted that health improvements are more profound. “We see sustained improvements in blood pressure, liver function and inflammation,” she said. “Those changes directly affect long-term heart disease and stroke risk.”
The risks of ‘all or nothing’
Some experts warn that adopting the Dry January trend could strengthen the urge to drink more in the other months, noting that some drinkers may find more success by slowly consuming fewer drinks per week.

Thomas Stopka, Ph.D., an epidemiologist and professor in the public health and community medicine department at Tufts University School of Medicine in Massachusetts, shared in a Futurity report that for some people, “damp January” may be more suitable.
One expert warned that not all drinkers should quit “cold turkey,” as it could lead to severe withdrawals. (iStock)
“Dry January is well-intentioned, and it may work really well for the people who can stick to it, maybe even beyond January,” he said. “Other people may be more inclined to cut down on alcohol consumption rather than quit drinking completely for the month.”

Stopka noted that successful harm-reduction approaches “aim to be judgment free.”
“Substance use disorder is a disease,” he said. “It takes time to treat the disease and to stay connected to the continuum of care — from prevention to treatment initiation to sustained therapy, whether through medication, self-help, or individual therapy or group support.”
