In the latest article from the series What Happens to Your Body When..., we explore the changes that occur in your body shortly after you say goodbye to alcohol.
Going a month without alcohol can really test your psyche. If you're used to a few glasses of wine every Friday or getting drunk with friends on Saturday nights, alcohol might have already done some damage to your body. The good news is you can quickly fix some of that damage—and enjoy a few perks along the way.
Finally Catch Some Z's
Surprisingly, one of the first perks of ditching alcohol is fresher breath and body odor. Your liver processes most of the alcohol you drink, but some exits through your urine, breath, and sweat. That's why heavy drinkers often have an unpleasant smell. Swap that shot of gin for a non-alcoholic drink, and you'll smell fresh even without deodorant.
Just a week without alcohol can do wonders for your sleep. Quality sleep involves cycling through six to seven REM cycles each night (REM stands for "Rapid Eye Movement," the deep sleep phase where major regenerative processes occur).
When you're drinking, you typically only get one or two REM cycles, which isn’t enough for proper recovery. Alcohol also messes with the release of melatonin in your brain, say sleep medicine specialists. So, even if alcohol helps you fall asleep faster, you'll still feel tired and sluggish the next day.
Plus, alcohol can cause you to wake up in the middle of the night and struggle to fall back asleep. It also worsens issues like sleep apnea. Experts recommend having your last drink at least four hours before bed.
More Energy and a Better Mood
Sure, we hear a lot about alcohol's impact on the liver, but it also affects the brain and nervous system. Alcohol-induced dehydration often leads to headaches—not even talking hangovers. If you're already prone to migraines or headaches, even a single glass of wine at dinner could leave you reaching for painkillers the next day.
Alcohol is also linked to a drop in sodium and potassium levels, negatively affecting the nervous system and muscle function. Lack of these minerals can cause headaches, fatigue, and nausea. Quit alcohol, and you'll likely experience fewer headaches.
With your nervous system in better shape, you'll feel less tired during the day, boosting your motivation and focus.
Eventually, your mental health will improve too. If you've ever tried drowning your sorrows or anxiety in booze, you probably noticed it doesn’t eliminate negative feelings—in fact, it can amplify them. Regular drinking disrupts the chemical balance in your brain (like reducing dopamine receptor function), crucial for mental well-being.
Better Sex and Glowing Skin
Let's be real, a glass of wine or a few cocktails often set the mood for bedroom fun. But too much alcohol can cloud your judgment and impair rational decision-making. Sometimes, it even prevents the act altogether.
Too much alcohol can make it difficult for men to achieve or maintain an erection. For women, it can lead to vaginal dryness, making sex uncomfortable or even painful. Try sober sex with your partner—you might find it lasts longer and is more satisfying.
After just a month without alcohol, your looks might improve—especially your skin. Alcohol dehydrates the body, causing the skin to lose fluids and nutrients, leading to more pronounced wrinkles, puffiness, or a dull appearance.
Dehydrated skin is also more susceptible to certain types of eczema. Alcohol affects circulation, worsening conditions like psoriasis (causing scaly skin) and rosacea (facial redness or hot flashes). Luckily, in a month (sometimes even sooner), your skin can start to heal.
Shed Pounds Effortlessly
If you used to drink several times a week and managed a month of "dry," you might have lost some weight without even realizing it.
Alcohol has about seven calories per gram, nearly as much as pure fat. Add the calories from sugary mixers and the food you eat while drinking (because everything tastes better after a few drinks), and you’ve got quite a calorie bomb.
Alcohol also slows metabolism, making it harder for your body to process fats and sugars. Your body prioritizes eliminating ethanol over basic tasks like nutrient absorption and fat burning, notes the UK nonprofit Drinkaware.
And here's an encouraging stat: In a study by the University of Sussex, over 58% of "Dry January" participants reported weight loss by month's end. More than 70% noticed an overall health improvement. Which brings us to the final point—if a month brings such benefits, what could total abstinence do?
Abstinence Could Prolong Your Life
Even after three weeks alcohol-free, you might notice improved blood pressure. Scientists have debunked the myth that moderate alcohol has health benefits. In reality, any drinking (this includes occasional toasts) can raise blood pressure and the risk for almost all heart diseases or strokes, states the World Heart Federation. So, cutting back on alcohol can reduce your risk of heart failure and early death.
Choose abstinence, and in the long run, you'll have a lower risk of developing age-related cancers in the intestine, breast, liver, or mouth compared to your peers who enjoy a few drinks every weekend.
The risk won’t decrease immediately. If you've been a heavy drinker, it could take years to lower it, warns the National Cancer Institute. For example, former drinkers had a higher risk of oral cavity and throat cancer even 16 years later compared to those who never drank. Of course, lifestyle and genetics play a role too.
If you're worried about your liver, here’s (probably) some good news. The liver is resilient and can regenerate. Experts say even a month without alcohol can improve liver function, enhancing hormone balance, nutrient storage, metabolism, and immunity.
However, every time the liver filters alcohol, some cells die and the liver can’t replace them indefinitely. If you drink heavily, you could weaken your liver’s regenerative abilities. Damaged liver can’t be repaired, so the only way to avoid this is to stop drinking for good.
