To find out, Columbia Magazine spoke with Katherine Keyes ’10PH, a professor of epidemiology at the Mailman School of Public Health and an expert on the health risks of our new drinking habits. But the good news is that these effects can be reversed in just weeks—suggesting that Dry January is more than just a buzzy health trend, as Rachel Fairbanks reported in October 2023. Drinking before bedtime can also fragment your REM sleep, and boost your risk for sleep apnea and alcohol addiction.
These open discussions have highlighted a growing recognition that alcohol often hinders, than than helps, in managing anxiety, getting quality sleep and staying emotionally resilient. Growing health and wellness consciousness, changing social patterns and evolving metacognition—an awareness of one’s own thought processes—have sparked their interest in the “sober curious” movement. Researchers have found that our bodies actually age in two “bursts” at 44 and 60, as Daryl Austin reported in September 2024. Those molecular changes can account for some of the sudden visible changes to our bodies such as sagging skin and wrinkles.
Ensembles encoding aspects of alcohol memories that difference between aa and na are important for reward learning, valuation, and action selection are not confined to the mPFC. Neuronal ensembles in most of these structures that are causally related to drug seeking, choosing, and taking have not yet been identified. However, using the Daun02 method, a neuronal ensemble in the central nucleus of the amygdala (CeA) was recently identified that is critical for alcohol self-administration during withdrawal from alcohol dependence102.
What does alcohol do to the body?
It has several uses within industry, including acting as a solvent, in the production of chemicals, as an ingredient in pesticides, and as an alternative fuel source. Many younger people are redefining what it means to have fun without the need for alcohol. For younger generations, meaningful social experiences are less about following traditional scripts and more about creating inclusive and intentional environments. Social media platforms appear to be playing a significant role in normalizing “intermittent sobriety”—a term that describes a pattern where individuals abstain from consuming alcohol and/or other substances for a select period of time. Social media platforms like Instagram and TikTok are powerful drivers of Gen Z’s relationship with alcohol.

She is a certified personal trainer, nutritionist and health coach with nearly 10 years of professional experience. Anna holds a Bachelor’s degree in Nutrition from the Warsaw University of Life Sciences, a Master’s degree in Nutrition, Physical Activity & Public Health from the University of Bristol, as well as various health coaching certificates. She is passionate about empowering people to live a healthy lifestyle and promoting the benefits of a plant-based diet. A 2014 review in the World Journal of Gastroenterology found that consuming more than five drinks a day can damage the pancreas, esophagus, stomach and intestinal tract. According to Boss, there’s a lot of scientific evidence to show that alcohol impacts the proper functioning of the brain, namely by affecting levels of neurotransmitters — chemical messengers in the brain. • Not buying alcoholic drinks that are unlabeled/have labels of poor quality, or that have a broken seal.
Efforts to bridge this knowledge gap have gained momentum over the past few years. As a generation that has grown up in a digital age where health information is more accessible than ever, Gen Z appears to be more aware of the adverse effects of alcohol compared to older generations. According to the World Health Organization, alcohol is linked to more than 200 health conditions, including cancer and liver disease.
International Patients
- In contrast, in animal self-administration and relapse models, nearly all rats acquire the respective behaviors, and individual variation is treated as random experimental error.
- In the U.S., moderate drinking is limited to two drinks per day for men and one drink per day for women, according to the Centers for Disease Control and Prevention (CDC).
- It is clear that these approaches can be clinically efficacious, even though their effect sizes are modest.
- Only about 25% of people with alcoholism ever receive treatment; for those who do, the lag from filling diagnostic criteria to receiving treatment is about a decade5.
So why is it so hard to know whether alcohol is good or bad for us—especially for our brains? In this post, we’ll explore the current science and some practical ideas on how to approach the topic. Scientific American is part of Springer Nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at /us). Scientific American maintains a strict policy of editorial independence in reporting developments in science to our readers.
This class of medications has the potential to achieve mechanistic and therapeutic effects similar to GABA-B agonists, while avoiding tolerance and overdose toxicity. We recently reported that the GABA-B PAM ADX71441 blocks stress-induced relapse to alcohol self-administration157. A key research question is whether the GABA-B PAM will also be able to normalize choice preference in the minority of rats that choose alcohol over a natural reward. The recent discovery that impaired GABA clearance in central amygdala is a causal factor behind pathological alcohol choice preference128 may also point to therapeutic strategies to rescue choice behavior, by recuing impaired GABA-clearance in the amygdala.
How does science provide solutions for drug use and addiction?
“When people cut out alcohol,” she says, “they often sleep better, feel mentally sharper, and have more energy.” She emphasizes that a successful shift toward sobriety often hinges on finding creative new ways to socialize and let loose. But whether it’s through mocktail meetups, outdoor activities, or game nights, there are other ways for people to party, hang out with their friends, and feel in the moment. “Turning the page on alcohol becomes easier when you discover new ways of connecting with people,” she says. Fermented beverages clearly eased the difficulties of everyday life—the workers who built the pyramids of ancient Egypt and Mesoamerica were paid in beer. Alcohol also knitted together, or “lubricated,” the social fabric of cultures by bringing humans together and warming them up to one another. Only about 25% of people with alcoholism ever receive treatment; for those who do, the lag from filling diagnostic criteria to receiving treatment is about a decade5.
