What Really Happens to Your Body a Week After You Stop Drinking
If you’re thinking about joining the #SoberCurious movement, you’re not alone. There are currently over 750,000 uses of the hashtag on Instagram, and more and more people are considering giving up alcohol as an experiment (think: Dry January but at other points in the year) — or for good. So what happens to your body when you stop drinking alcohol? We asked experts to break down everything you might notice immediately, and the effects that can continue long after you’ve had your last sip.
What does alcohol do to your body?
You’d be hard-pressed to think of something in your body that isn’t impacted by alcohol. According to Matthew Mosquera, MD, the Medical Director of the Alcohol, Drugs, and Addiction Inpatient Program at McLean Hospital in Belmont, Massachusetts and an instructor of psychiatry at Harvard Medical School, alcohol affects three main systems in your body:
Liver
Light drinkers tend to be mostly spared from the effects on the liver, but for heavy drinkers, the liver becomes inflamed, which can be dangerous over time,” says Dr. Mosquera. According to The National Institute for Health, light drinking is defined as seven drinks per week for women, with no more than three in one day, and no more than 14 drinks per week for men, with no more than four in one day. That said, your liver has to work hard to process and filter alcohol, no matter the quantity. When you’re drinking heavily on a regular basis, it can overwhelm the liver’s capabilities, causing a cascade of health issues, including liver disease, liver cancer, and acute alcohol-related hepatitis — all of which can be deadly.
Cardiovascular System
“Alcohol is a monkey wrench in our homeostasis,” says Dr. Mosquera. “Both light and heavy drinking dehydrates you, so your heart compensates by elevating your blood pressure and your heart rate.” In fact, an analysis of seven studies in the journal Hypertension, found that people who had just one drink per day showed elevated blood pressure when compared to non-drinkers.
Cognitive Function
Drinking increases anxiety levels and impairs your memory’s ability to function, adds Dr. Mosquera. But we’re not just talking about one night of “blacking out” and forgetting what happened. The compound effects of drinking on your brain can be serious. One study found that even moderate alcohol consumption can cause changes to the brain’s structure, leading to cognitive decline in areas associated with memory and reasoning. In the study, more excessive drinking translated to more rapid cognitive decline.
While these areas may take the greatest hit from regular drinking, they aren’t the only ones affected. Alcohol’s inflammatory properties don’t just affect the liver — the stomach can also become inflamed, which, along with the dehydration, can affect digestion and lead to constipation. While your liver and stomach can usually rebound if you stop drinking, with inflammation comes an increased cancer risk over time.
Alcohol can also impair your ability to get restorative rest because you’re less likely to enter REM sleep, which has been shown to increase your risk of dementia.
Regular drinking raises estrogen levels and reduces testosterone. For men, this can look like lowered libido and erectile dysfunction, as well as decreased muscle mass. For women, it can increase the risk of breast cancer, impair bone health, and lead to mood changes.
And, emotionally, alcohol can make you not only more anxious, but more irritable, more impulsive and less inhibited — not just after a drink, but compounded over time, says Dr. Mosquera. These effects can also be exacerbated if you have a mental health diagnosis like bipolar disorder, he says.
What happens to your body when you stop drinking?
Ironically, some of the first things you might notice are similar to what happens to your body when you’re drinking. “Anxiety is the most common thing people notice upon stopping,” says Dr. Sharone Abramowitz, MD, a psychiatrist and president of the California Society of Addiction Medicine. She also notes that a craving for alcohol is common once people stop.
Other common side effects:
rapid heart rate
nausea
restlessness
sleep problems
The good news? These effects will subside as your body adjusts to the absence of alcohol.
Alcohol withdrawal timeline
The first few days:
Some positive effects of no alcohol will come on after just a few days of giving up your nightly nightcap. Alcohol inhibits your ability to reach a REM state while asleep, so after a few days without alcohol, you’ll start to notice that you’re dreaming more and getting deeper, more restorative rest. “You’re also more hydrated, so your heart rate will start to go down,” says Dr. Mosquera. “After a few days, you’ll notice an increase in energy and more mental clarity.”
After a week:
After just seven days without alcohol, your immune system starts bouncing back. While you might not notice it, your hormones are starting to improve as well, with libido and sexual function revving back up. While heavy drinkers are the only ones who experience liver effects from alcohol, the improvements can be felt very quickly. “If you’re a heavy drinker, this is where your liver health starts rebounding,” says Dr. Mosquera.
After a month:
Your body’s systems bounce back over time, but after about 30 days, you’ll start seeing a difference. “Your skin has had a month to absorb all the hydration and nutrients and B vitamins that your body hadn’t been getting while you were drinking, so this is when you’ll see noticeable improvements to your skin,” says Dr. Mosquera. There’s also likely to be some weight loss within a month, due to the absence of the calories you were ingesting in alcohol (as long as you haven’t swapped them for equally high-calorie comfort foods).
After 3 months:
Consider this when the cloud will start lifting mentally. “After a few months, the brain will begin to return to health,” says Dr. Abramowitz. Your alcohol-induced anxiety levels have likely stabilized, too. Your sleep cycle is continuing to improve, so you’re getting even more REM sleep and feeling more rested.
After 6 months:
Six months without alcohol is when you can begin to see your immune system optimizing and fighting the good fight again, though depending on the time of year and your environment, you might not immediately notice. If it’s winter, you may notice fewer colds than in the past, but in warmer months, the changes may be more subtle, but that doesn’t mean they aren’t there. Your body is starting to operate more efficiently, too. “Giving your body six months of water absorption will improve your digestion and constipation,” says Dr. Mosquera.
After a year:
“The one-year mark is when your overall risk of different cancers has leveled off,” says Dr. Mosquera. “No level of drinking is safe when it comes to cancer risk, but after a year without alcohol, you’ve experienced a significant risk reduction.” After all this time, you might also appreciate a lot of the emotional effects of a life without alcohol. “Your relationships are likely improved, and your resilience has increased,” says Dr. Mosquera.
On top of that, you’re likely feeling less anxiety and are better able to regulate your emotions when life’s hiccups arise.
How to stop drinking
Depending on whether you’re a light or heavy drinker, your strategy around cutting back will be different. “For a light drinker, you don’t really need to taper,” says Dr. Mosquera. “Heavy drinkers should make a plan to avoid withdrawal symptoms like seizures.” If you’re drinking more than seven drinks a week for a woman or 14 for a man, especially for extended periods of time, consider talking to a doctor first before stopping cold turkey.
If you’re considering a break from alcohol, it might also be helpful to think about why you drink. “Everyone turns to alcohol for a reason,” says Dr. Mosquera. “Maybe it’s relief from your worries or connection with friends. Try to think about what you’ll replace alcohol with so that you can still get that outlet.” Instead of meeting friends regularly at a bar to connect and wind down, suggest a new workout class you could do together or just meet up for a walk. If drinking is your go-to way to blow off steam after a busy week, schedule a booze-free, self-care activity for Friday afternoons, like indulging in a hobby you enjoy or a pampering session like a massage.
Bottom line
Quitting without a plan can be extra tough because you’ll still want to fill the emotional void that alcohol used to sop up. Make sure you have another strategy lined up that actually works for you (i.e., don’t say you’ll take up yoga if you hate yoga), so you won’t feel tempted to rush back to drinking when life gets stressful. Another potential option: The rise in great-tasting non-alcoholic beverages may make the switch even easier.
