Alcohol and Menopause: Why It Can Feel Different in Midlife
Updated: Oct 2
Maybe you used to have wine with dinner and sleep just fine. Now even one drink leaves you wide awake at 3 a.m. Or you notice that you get flushed, your hot flashes seem worse, or you feel surprisingly lousy the next morning.
If that sounds familiar, you're not imagining it.
Many women notice that alcohol just doesn't agree with them the way it used to during perimenopause and menopause. There are several reasons this can happen, and they aren't all about estrogen.
Alcohol also deserves a closer look in midlife because its health effects become increasingly relevant as we get older. That doesn't mean you need to give up your Friday night glass of wine. It does mean it's worth understanding what you're drinking, how much you're drinking, and how it affects you.
Why does alcohol feel different in menopause?
As we age, body composition changes. We generally have less total body water and, often, less muscle mass. Because alcohol is distributed in body water, the same amount of alcohol can produce a higher blood alcohol concentration than it did when we were younger.
Medications can also become part of the equation. Many women take more medications in midlife, and alcohol can interact with some of them. This is especially relevant with sleep medicines, benzodiazepines, opioid pain medicines, some anxiety or depression medicines, antihistamines, and medications that can affect the liver or blood sugar. If you take an opioid or benzodiazepine, I'd ask your prescriber or pharmacist specifically about alcohol rather than assuming that taking them at different times makes the combination safe. For other medications, the risks vary depending on the specific medication, dose, and how much you drink, so check with your pharmacist or clinician if you're unsure about a particular combination.
Sleep can become more fragile in midlife, which I describe more in Menopause and Sleep Problems: What's Really Happening at 3am and What Actually Helps. Hot flashes and night sweats also can interrupt the night, and many women find that they wake more easily or have a harder time getting back to sleep. You can read more about treatments for hot flashes in Beyond Hormones: Navigating Your Options for Hot Flashes and Night Sweats.
Alcohol makes you sleepy at first, but that doesn't mean you'll sleep better, because it can disrupt the second half of the night. If you already tend to wake up at 3 a.m., that glass of wine may be part of the reason you're staring at the ceiling. Alcohol can also worsen snoring and obstructive sleep apnea by relaxing the muscles that help keep the upper airway open. Obstructive sleep apnea becomes more common in women during and after the menopause transition.
Hot flashes are the other piece. Alcohol can make some people feel warm or flushed, in part because it affects blood vessels near the skin. If you are already prone to hot flashes, that sensation may be enough to trigger one or make it feel more noticeable. Research looking at alcohol and menopausal symptoms has not been perfectly consistent, so I wouldn't tell every woman that alcohol will make her hot flashes or night sweats worse. But if you've noticed a predictable pattern, trust it. You may be one of the women for whom alcohol is a trigger.
Alcohol and your overall health
The effects of alcohol aren't limited to how you feel the next morning. They also matter for long-term health.
Breast cancer is one of the cancers linked to alcohol use, and the association is seen even at relatively low levels of intake. In large studies, risk rises by roughly 7 to 10% for each additional drink a day. That's a relative increase on top of a lifetime risk of about 1 in 8, so for someone who drinks occasionally the absolute change is small. Still, it's one of the few breast cancer risk factors you can adjust.
Beyond breast cancer, higher intake is associated with other cancers, high blood pressure, atrial fibrillation, liver disease, sleep disruption, and mood symptoms. Some of that risk shows up even at low levels, particularly for certain cancers and blood pressure, while atrial fibrillation is clearest with heavier and binge drinking.
Alcohol can also raise the risk of injuries and falls, especially when it is combined with sedating medications, poor sleep, balance problems, or other factors that can become more relevant with age.
Make sure you know what counts as a drink
This is surprisingly easy to get wrong.
In the United States, one standard drink is:
12 ounces of regular beer
5 ounces of wine
1.5 ounces of 80-proof distilled spirits
A restaurant pour may contain more than one standard drink. A 6-ounce pour of 12% wine is about 1.2 standard drinks. A generous 9-ounce pour is about 1.8 standard drinks.
And many craft beers contain considerably more alcohol than the typical 5% used to define a standard beer.
So when someone tells me she has "one glass of wine every night," I want to know what that glass actually looks like.
