For decades, studies suggested that moderate drinkers lived longer than non-drinkers, and red wine gained a reputation as good for the heart. That idea has been seriously challenged.
What went wrong with the old studies
Many earlier studies compared moderate drinkers with “non-drinkers” — a group that often included people who had stopped drinking because of illness. That made non-drinkers look less healthy and moderate drinking look protective. When researchers corrected for these biases, much of the apparent benefit disappeared.
Where the evidence stands now
In 2023, the World Health Organization stated that no level of alcohol consumption is safe for health. Alcohol is classified as a carcinogen and is linked to at least seven cancers.
For women, breast cancer is a particular concern: risk rises with alcohol intake, even at low levels. The National Cancer Institute notes that drinking increases breast cancer risk.
Midlife considerations
- Alcohol can trigger hot flashes and night sweats.
- It disrupts sleep, especially in the second half of the night.
- It adds calories and can contribute to abdominal weight gain.
- Women tend to reach higher blood alcohol levels than men from the same amount.
A balanced perspective
This doesn’t mean an occasional drink is dangerous — risk is dose-dependent, and lower intake means lower risk. But there’s no health reason to start drinking, and less is better for those who do.
Practical steps
Try alcohol-free days during the week, choose smaller servings, alternate with water, and explore alcohol-free alternatives. Notice how your sleep and energy change.
