Is drinking wine every night a problem?

It depends on how much you pour and whether you can skip it. One true 5-ounce glass a night is about 7 standard drinks a week, which sits right at the US line where risk starts to rise for women. Two big home pours a night is closer to 25 a week, well past the lines for anyone.

The other half of the answer is the habit. A glass you choose is different from a glass you feel you need. The plainest test is to skip a few nights and see what happens. Below: what your nightly wine adds up to, what it does to health and sleep, the signs that it has become more than a habit, and how to keep wine without the every-night routine.

What "a glass of wine every night" really adds up to

In the US, one standard drink holds 14 grams of pure alcohol. For table wine at about 12% alcohol, that is 5 ounces, according to the National Institute on Alcohol Abuse and Alcoholism (NIAAA). Most home glasses hold far more than that, so "one glass" is often closer to two drinks.

Worked out from NIAAA's standard drink. Strong reds at 14–15% carry about a fifth more alcohol per glass than the 12% column.

Now compare with NIAAA's lines for heavy drinking: more than 3 drinks on any day or 7 a week for women, and more than 4 on any day or 14 a week for men. One measured glass a night keeps most men under the weekly line and puts women right on it. A generous pour, or a second glass, takes nearly everyone over it.

Try it tonight: pour your usual glass, then tip it into a measuring cup. That one number tells you more than any article.

Is one glass of wine a night bad for you?

A single measured glass most nights is low risk compared with heavier drinking, but it is not risk-free, and the advice has shifted in the last few years:

• Cancer. The US Surgeon General's advisory in January 2025 called alcohol the third leading preventable cause of cancer in the US, after tobacco and obesity. Risk for some cancers, breast cancer among them, starts rising at about one drink a day. Red or white makes no difference: the alcohol is the cause.
• The red wine and heart story. The idea that a daily glass protects the heart came from studies that compared moderate drinkers with non-drinkers. Many non-drinkers in those studies had quit because of illness, which made moderate drinkers look healthier than they were. The 2025–2030 Dietary Guidelines for Americans no longer give a daily amount; they simply advise drinking less for better health.
• Medicines and conditions. Even one glass matters if you take sleeping pills, some pain or anxiety medicines, or blood thinners, if you have liver disease, or if you are pregnant or trying to be. Ask your doctor or pharmacist.

So the honest answer for one real glass a night is: not a crisis, and less is better. For a closer look at the weekly lines and what most Americans actually drink, see how many drinks a week is normal.

What about two glasses, or a bottle, every night?

Two big glasses a night is about 25 standard drinks a week: above NIAAA's heavy-drinking line for both men and women. A bottle a night, about 35 drinks a week, is several times over it. At these amounts the risks climb for high blood pressure, liver disease, heart rhythm problems and several cancers, and drinking every day at this level is how the body adapts to alcohol and starts to miss it when it's gone.

If this is you and it has been going on for months or years, don't stop all at once without advice. People who drink heavily every day can have withdrawal when they stop suddenly (shaking, sweating, racing heart, anxiety, and in severe cases seizures). A doctor can help you cut down safely, sometimes with medicine.

What nightly wine does to your sleep

Wine can help you fall asleep, which is part of why the evening glass is so easy to keep. The trouble comes later. As the body clears the alcohol in the second half of the night, sleep gets lighter and more broken, and dream (REM) sleep is cut short. Many people who drink most nights wake around 3 a.m., get up to use the bathroom, or wake tired after a full night in bed.

If you drink every night, you may have forgotten what sleep feels like without it. A week of wine-free nights is often the first place people notice a difference. The full list of what changes, and when, is in the benefits of drinking less alcohol.

Weight, blood pressure and mood

• Weight. A 5 oz glass of table wine is about 120–125 calories (USDA FoodData Central). Two 9 oz pours a night add up to around 3,000 calories a week, before the cheese and the late snacks that often come with them.
• Blood pressure. Regular drinking raises blood pressure, and the more you drink the more it rises. A review in The Lancet Public Health (2017) found that people who drank more than 2 drinks a day saw their blood pressure fall when they cut down.
• Mood. The glass that eases a hard day can leave you flatter and more anxious the next one. If you notice you look forward to the glass more each week, or feel low on the nights you skip, that is worth paying attention to.

A habit or a problem? The signs that matter

Drinking every night doesn't by itself mean you have a drinking problem. Doctors diagnose alcohol use disorder (AUD) from what drinking does to your life, not from the calendar. NIAAA puts the 11 signs as plain questions. In the past year, have you:

1. Ended up drinking more, or for longer, than you meant to?
2. Wanted to cut down or stop more than once, or tried, and couldn't?
3. Spent a lot of time drinking, or being sick or tired from it?
4. Wanted a drink so badly you couldn't think of anything else?
5. Found that drinking, or feeling sick from it, got in the way of home, family, work or school?
6. Kept drinking even though it caused trouble with family or friends?
7. Given up or cut back on things you enjoyed so you could drink?
8. Got into situations, while or after drinking, that raised your chance of getting hurt (driving, swimming, unsafe sex)?
9. Kept drinking even though it made you feel depressed or anxious, added to another health problem, or after a memory blackout?
10. Had to drink much more than before to get the effect you want, or found your usual amount had much less effect?
11. Found that when the alcohol wore off you had trouble sleeping, shakiness, restlessness, nausea, sweating, a racing heart, or felt things that weren't there?

Two or three of these in the past year is what doctors call mild AUD, four or five moderate, six or more severe. If you said yes to two or more, talk to a doctor. That isn't a label; it is the point at which help works best. If you said yes to none, but you're drinking above the weekly lines, the job is cutting back, and that is something many people do on their own.

Most people who drink a lot are not dependent. A CDC study of US adults found about 9 in 10 people who drank too much did not meet the criteria for alcohol dependence (Esser and colleagues, 2014). For them, nightly wine is a habit tied to a time and a feeling, and habits can be changed.

The 7-day skip test

The quickest way to learn what your nightly glass means to you is to take it away for a few nights on purpose. This isn't a cure or a diagnosis, just information.

1. Pick 3 nights in the next 7 with no wine at all, ideally including one you'd usually find hard (a Friday, or after a long day).
2. Keep the ritual, change the glass. Same time, same glass, something else in it: sparkling water with lime, tea, a non-alcoholic wine.
3. Write two lines each night: how strong the urge was (0–10) and what was going on when it peaked.
4. Note your sleep and your morning the next day, in a word or two.

Most people land in the second row. The urge shows up at the same time, in the same place, and fades in 20–30 minutes if you don't act on it. That's useful: it means the thing to change is the moment, not your character.

Why "every night" is the part worth changing

Every time you pour at the same cue, the link between the cue and the glass gets stronger. After a few years, getting home, starting dinner or sitting down on the couch can feel incomplete without wine. Dry days break that link. They also give your liver and your sleep regular nights off, and they make the weekly total much easier to keep down. NIAAA's own cutting-down tips start with the same two things: set a limit, and keep some days alcohol-free.

How to keep wine without the nightly routine

You don't have to give wine up to stop drinking it every night. A plan that works for many people:

• Name your wine nights. "Friday, Saturday and Sunday dinner" beats "less during the week". Deciding at 6 p.m. is where plans give way.
• Measure, then shrink the glass. Use small glasses, or mark a 5 oz line on your favorite.
• Buy for the plan. One bottle for three wine nights. A case or a box turns every evening into a fresh decision.
• Replace the moment, not just the drink. If wine means "the day is over", build a new end-of-day step: change clothes, a short walk, a shower, then dinner.
• Start later. If wine starts at 6 while cooking, move it to dinner at 7:30. Fewer hours, fewer glasses.
• Count it. A simple log of pours per week shows progress long before the scale or the sleep does.

When to see a doctor

• You drink most days and feel shaky, sweaty, sick or very anxious when you skip.
• You answered yes to two or more of the 11 signs above.
• You've tried several times to cut down and couldn't stick to any limit.
• You have liver disease, high blood pressure, heart rhythm problems, or take medicines that mix badly with alcohol.
• You are pregnant or trying to be.

Doctors see this every day, and there are medicines that reduce cravings. NIAAA's free Alcohol Treatment Navigator helps you find care near you, and SAMHSA's free, confidential helpline is open around the clock: 1-800-662-4357.

Questions people ask

Is a glass of wine every night bad?

One true 5 oz glass is about 7 drinks a week: low risk next to heavy drinking, but not risk-free, mainly because of cancer risk. Most home glasses are bigger than 5 oz, so measure yours. Adding a few dry nights a week lowers the total and keeps the habit in your hands.

Is it OK to drink 2 glasses of wine every night?

Two 5 oz glasses is 14 drinks a week: twice the NIAAA heavy-drinking line for women and right at it for men. Two big home pours is around 25. At that level, cutting back is worth doing, and dry nights are the easiest place to start.

Am I an alcoholic if I drink wine every night?

Not by that alone. Doctors look at the 11 signs above: whether you can control it, whether you crave it, whether it causes trouble, whether you feel unwell without it. Two or more signs in a year is a reason to talk to a doctor.

Is red wine every night good for your heart?

That idea has not held up well. Earlier studies made moderate drinkers look healthier partly because many non-drinkers had quit for health reasons. Current US guidance advises drinking less, not drinking for health.

How long does it take to break the nightly wine habit?

It varies from person to person, but the urge at your usual time usually gets weaker the more evenings you get through without acting on it. Most people find the first week the hardest. Keeping the ritual (same glass, different drink) makes it much easier.
