Drinking is harmful to your health at any age. But as you get older, the risks become greater — even with the same amount of drinks.
Alcohol affects “virtually every organ system in the body”, including the muscles and blood vessels, digestive system, heart and brain, said Sara Jo Nixon, the director of the Center for Addiction Research & Education at the University of Florida. “It particularly impacts older adults, because there’s already some decline or impact in those areas.”
“There’s a whole different set” of health risk factors for older drinkers, said Paul Sacco, a professor of social work at the University of Maryland, Baltimore who studies substance use and aging. People might not realise that the drinks they used to tolerate well are now affecting their brains and bodies differently, he said.
Alcohol can present new problems in older age — particularly at 65 and up — for even light or occasional drinkers. Older adults tend to have less muscle mass and retain less water in their tissues compared with younger people, which can increase blood alcohol concentration, said Aaron White, a senior advisor at the National Institute on Alcohol Abuse and Alcoholism. This means it takes fewer drinks for older people to feel intoxicated, and heightens the risk of severe injury from falls.
According to Dr Nixon’s research, older people also show deficits in working memory at lower blood alcohol concentrations than younger drinkers. In another study Dr Nixon worked on, some older adults in driving simulations showed signs of impairment after less than one drink.
Drinking alcohol can increase the risk of developing chronic conditions like dementia, diabetes, cancer, hypertension and heart disease.
But it can also worsen outcomes for the majority of older adults already living with chronic disease, said Aryn Phillips, an assistant professor of health policy and administration at the University of Illinois Chicago who studies alcohol and aging.
Drug interactions also come into play. Mixing alcohol with prescription medicines that older adults commonly take, such as those for treating diabetes or hypertension, can make the medications less effective or cause harmful side effects, like ulcers or an irregular heart beat. Benzodiazepines, when combined with alcohol, can slow breathing and act as a powerful sedative.
Even over-the-counter medication can be dangerous. Aspirin, which some older people take to reduce cardiovascular disease risk (despite the potential side effects), can lead to severe gastrointestinal bleeding, which older people are already at higher risk for, said Michael Wheeler, a professor of nutrition science at East Carolina University who researches alcohol-induced liver disease.
Some older adults also contend that hangovers worsen with age. While there’s no strong scientific evidence supporting this, the hangovers may seem worse because alcohol can exacerbate other symptoms of aging, like poor sleep, Dr White said.
Experts said alcohol use among older adults appears to have risen in recent years, though national trends are difficult to track outside of self-reported surveys. A federal survey from 2023 found that 12 per cent of adults 65 and older — about seven million people — reported drinking at least four or five drinks in a sitting in the previous month.
After decades of mixed messaging around alcohol’s health harms and benefits, recent studies have made it clear that no amount of alcohol is good for you.
Still, Dr Sacco acknowledged that “drinking has meaning for people”, and whether to moderate or quit altogether “is a call that you have to make in consultation with your doctor and your loved ones”.
But what is a “safe” amount of drinking for the older set? That’s difficult to say.
The available studies attempting to establish exactly how much alcohol it takes to drive up health risks in older populations use different benchmarks for moderate drinking, making it tricky to draw a consensus. “Even as an expert in this field, I understand the confusion,” Dr Wheeler said.
