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 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.”

Eating processed meat like ham, sausage and bacon may be linked to a higher risk of certain types of cancer, according to new research.
While health organizations have already confirmed that processed meat can contribute to colon cancer, this study looked closer at cancers in the upper digestive tract, where the link has historically been less clear.
To understand these connections, researchers from the European Prospective Investigation into Cancer and Nutrition (EPIC), one of the world’s largest long-term nutrition and cancer cohorts, tracked the health and diets of 450,112 people across Europe for an average of 14 years.
FREQUENT HEARTBURN MAY BE A WARNING SIGN OF A MORE DANGEROUS CONDITION, DOCTOR SAYS
The study group included 131,426 men and 318,686 women, according to the study’s press release.
During the follow-up period, 876 people developed stomach cancer and 215 people developed esophageal adenocarcinoma, which is cancer of the tube connecting the mouth to the stomach.
For female participants, eating both processed meat and white meat was linked to an increased risk of developing the disease. (iStock)
Researchers tracked where the stomach cancers grew, separating them into the upper part of the stomach near the throat and the lower part of the stomach.
The researchers also sorted the tumors into two categories based on how the cancer cells appeared under a microscope: intestinal, which forms more organized structures, and diffuse, in which the cells are more scattered throughout the tissue.
BACTERIA IN YOUR MOUTH MAY TRAVEL TO THE GUT AND TRIGGER STOMACH CANCER, RESEARCH FINDS
After adjusting for other lifestyle factors, the researchers found that for every extra 30 grams of processed meat a person ate per day, their overall risk of stomach cancer went up by 9%. Eating that same extra 30 grams a day was also linked to a 13% higher risk of esophageal adenocarcinoma.
A standard single slice of regular deli-sliced ham or lunch meat averages around 28 grams, according to USDA data and nutritional tracking databases.
An extra 20 grams of white meat, such as chicken and turkey, was linked to a 12% higher risk of cancer in the main body of the stomach. (iStock)
An extra 20 grams of white meat, such as chicken or turkey, was linked to a 12% higher risk of cancer in the main body of the stomach, the researchers noted.
The study also revealed differences between men and women. For male participants, only processed meat showed a clear, statistically significant link to a higher risk of stomach cancer. For female participants, however, eating both processed meat and white meat was linked to an increased risk.

These findings align with global health benchmarks, particularly those established by the World Health Organization’s International Agency for Research on Cancer.
The agency has long classified processed meat as a known human carcinogen, primarily due to its strong, well-documented links to colorectal cancer.

However, health organizations have also consistently pointed to a potential, yet less definitive, relationship between these meats and cancers of the stomach.

Further scientific investigation is needed to confirm the findings and to account for other underlying risk factors, such as certain stomach infections, which could interact with dietary habits.

A key limitation of the study is its reliance on self-reported diets, which can sometimes lead to inaccuracies in how participants recall their meat consumption over time, the researchers noted.

Yoga is known to boost relaxation, strength and flexibility – and now a new study has found the practice could improve cancer survivors’ quality of life.
A randomized trial led by the University of Rochester Medical Center found that a four-week yoga program significantly reduced insomnia, fatigue, anxiety and mood disturbances after cancer treatment.
The findings were presented last week at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago.
CANCER SURVIVORS MAY SEE SURPRISING BENEFITS FROM ONE SPECIFIC EXERCISE, STUDY SAYS
The study was conducted across multiple U.S. community cancer care sites, including 410 adult cancer survivors averaging 54 years of age. Around 75% were breast cancer survivors, and none of them had practiced yoga regularly within the prior three months.

The participants were randomly assigned to two groups. Half of them received only standard survivorship care without the yoga, while the other half received standard care and were also enrolled in the Yoga for Cancer Survivors (YOCAS) program.
As part of the YOCAS program, the survivors completed two instructor-led 75-minute yoga sessions each week, including 18 Gentle Hatha yoga and Restorative yoga poses, breathing exercises and mindfulness training.
EATING MORE FRUITS AND VEGETABLES LINKED TO SURPRISING EFFECT ON SLEEP
Based on questionnaires completed by the patients, the survivors in the yoga group experienced “moderate-to-large” reductions in overall mood disturbance, “small-to-medium” reductions in anxiety and “medium-to-large” reductions in fatigue, the study found.
The improvements in mood and fatigue appeared to be linked to yoga’s beneficial effect on sleep quality, according to the researchers.

“This indicates that cancer survivors have an option to alleviate these cancer-related side effects at the same time, without adding another drug,” lead investigator Yuri Choi, PhD, of the Wilmot Cancer Institute, University of Rochester Medical Center, in Rochester, New York, told Fox News Digital.
The study did not reveal any major safety concerns or serious adverse events related to the yoga practice.

The study did have some limitations, chiefly that the findings are preliminary and have not yet been peer-reviewed for a medical publication.

“The sample in our clinical trial was relatively homogeneous, with most participants being women (96%), breast cancer patients (75%), Caucasian (93%), and having some college or higher education (82%),” noted Choi.
“We are adapting our intervention to reach all cancer patients and survivors, including the creation of a mobile app to reach people in rural communities.”

The research also excluded patients with metastatic cancer (whose disease had spread to other parts of the body).
The total study was only four weeks, so more research is needed to determine long-term benefits.
If the findings are confirmed by peer-reviewed publications, this could lead to recommendations for structured yoga programs as a non-drug supportive therapy for cancer survivors, the researchers noted. (iStock)

Some yoga studios may use different names for Gentle Hatha and Restorative yoga, such as Foundations Yoga or Healing Yoga, Choi noted.

“Survivors should also look for certified yoga instructors who have experience working with cancer patients/survivors or individuals with other challenging health conditions,” the researcher advised. “They should not be afraid to ask their oncology team for referrals to qualified instructors in their community.”

Choi also noted that the research did not reveal whether other types of yoga, such as heated-room or rigorous-flow yoga, are safe or beneficial for cancer survivors.
The study was funded by the National Cancer Institute.
