Doctor reveals what 30 days without alcohol does to the brain and body amid Dry January

NEWYou can now listen to Fox News articles!

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.

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 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.

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.”

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.”

Experts reveal why ‘nonnamaxxing’ trend may improve mental, physical health

NEWYou can now listen to Fox News articles!

The key to feeling better in a fast, overstimulated world might be surprisingly simple: Live a little more like your grandparents.

A growing social media trend, dubbed “nonnamaxxing,” draws inspiration from the slower, more intentional rhythms associated with an Italian grandmother.

The lifestyle is often linked to activities like preparing home-cooked meals, spending time outdoors and making meaningful connections.

“Nonnamaxxing is a 2026 trend that embraces the slower, more intentional lifestyle of an Italian grandmother (a Nonna). Think cooking from scratch, long family meals, daily walks, gardening and less screen time,” Erin Palinski-Wade, a New Jersey-based registered dietitian, told Fox News Digital.

Stepping away from screens and toward real-world interaction can have measurable benefits, according to California-based psychotherapist Laurie Singer.

“We know that interacting with others in person, rather than spending time on screens, significantly improves mental health,” she told Fox News Digital, adding that social media often fuels comparison and lowers self-esteem.

Living more like previous generations isn’t purely driven by nostalgia. Cooking meals from scratch, for example, has been linked to better nutrition and more mindful eating patterns.

Adopting traditional mealtime habits can improve diet quality and support both physical and mental health, especially when meals are shared regularly with others, Palinski-Wade noted.

There’s also a psychological benefit to slowing down and focusing on one task at a time. Anxiety often stems from unfinished or avoided tasks, Singer noted, and engaging in hands-on activities can counteract that.

“Nonnamaxxing encourages us to be present around a task, like gardening, baking or knitting, or just taking a mindful walk, that delivers something ‘real,’” she said.

Palinski-Wade cautions against turning the trend into another source of pressure, noting that a traditional “nonna” lifestyle often assumes a different pace of life.

The key, she said, is adapting the mindset, not replicating it perfectly.

Singer added, “Having a positive place to escape to, through whatever activities speak to us and make us happy, isn’t generational – it’s human.”

Loneliness may be silently eroding your memory, new research reveals

Loneliness may be silently eroding your memory, new research reveals

NEWYou can now listen to Fox News articles!

Feeling lonely may take a toll on older adults’ memory — but it may not speed up cognitive decline, according to a new study.

Researchers from Colombia, Spain and Sweden analyzed data from more than 10,000 adults ages 65 to 94 across 12 European countries and found those who reported higher levels of loneliness did worse on memory tests at the start of the study, according to research published this month in the journal Aging & Mental Health.

Over a seven-year period, however, memory decline occurred at a similar rate regardless of how lonely participants felt.

“The finding that loneliness significantly impacted memory, but not the speed of decline in memory over time was a surprising outcome,” lead author Dr. Luis Carlos Venegas-Sanabria of the School of Medicine and Health Sciences at the Universidad del Rosario said in a statement.

“It suggests that loneliness may play a more prominent role in the initial state of memory than in its progressive decline,” Venegas-Sanabria said, adding that the findings highlight the importance of addressing loneliness as a factor in cognitive performance.

The findings add to debate about whether loneliness contributes to dementia risk. While loneliness and social isolation are often considered risk factors for cognitive decline, research results have been mixed.

The study looked at data from the long-running Survey of Health, Ageing and Retirement in Europe (SHARE), which tracked 10,217 older adults between 2012 and 2019. Participants were asked to recall words immediately and after a delay to measure memory performance.

Loneliness was assessed using three questions about how often participants felt isolated, left out or lacking companionship.

About 8% of participants reported high levels of loneliness at the outset. That group tended to be older, more likely to be female and more likely to have conditions such as depression.

Researchers found that those with higher loneliness had lower scores on both immediate and delayed memory tests at baseline. Still, all groups — regardless of loneliness level — experienced similar declines in memory over time.

The results suggest loneliness may not directly accelerate the progression of memory loss, though it remains linked to poorer cognitive performance overall.

Experts warn, however, that the findings should not be interpreted to mean loneliness is harmless.

“The finding that lonely older adults start with worse memory but don’t decline faster is actually the most interesting part of the paper, and I think it’s easy to misread,” said Jordan Weiss, Ph.D., a scientific advisor and aging expert at Assisted Living Magazine and a professor at NYU Grossman School of Medicine.

“It likely means loneliness does its damage earlier in life, well before people show up in a study like this at 65-plus,” Weiss told Fox News Digital.

By older age, long-term social patterns may already be established, making it harder to detect when the effects of loneliness first took hold, an aging expert says. (iStock)

“By the time you’re measuring someone in their late 60s, decades of social connection patterns are already baked in,” he said.

Weiss, who was not involved in the research, added that loneliness may coincide with other health conditions, and noted that participants who felt more isolated also had higher rates of depression, high-blood pressure and diabetes. The link, he said, may reflect a cluster of health risks rather than a direct cause.

“While they can go hand-in-hand, it’s not clear that loneliness contributes to dementia,” a psychotherapist says. (iStock)

Amy Morin, a Florida-based psychotherapist and author, said the findings reflect a broader pattern in research on loneliness and brain health, and that the relationship may be more complex than it appears.

“The evidence shows there’s a link between loneliness and cognitive decline but there’s no direct evidence of a cause and effect relationship,” she said. “So while they can go hand-in-hand, it’s not clear that loneliness contributes to dementia.”

Morin added that loneliness, which can fluctuate, may not be the root of the problem, but rather a symptom of other underlying mental or physical health issues.

She said staying socially and mentally engaged is crucial for overall brain health.

“It’s important to be proactive about social activities,” Morin said. “Joining a book club, having coffee with a friend, or attending faith-based services can be a powerful way to maintain connections in older age.”

The researchers also suggested screening for loneliness be incorporated into routine cognitive assessments as one way to support healthy aging.
