We’ve all heard mixed messages about alcohol and heart health. Some say a glass of red wine is good for your heart, while others warn against the risks of excessive drinking.
A recent study led by scientists from Massachusetts General Hospital tries to shed some light on this subject. They looked at how small to moderate amounts of alcohol might be affecting our hearts and the stress signals in our brains.
A Surprise in the Data
Previous studies had suggested that a modest amount of alcohol—like one drink a day for women and up to two drinks a day for men—could potentially lower heart disease risk.
However, it was unclear whether this was due to the alcohol itself or other factors, like healthier lifestyles or higher incomes among moderate drinkers.
This study took data from more than 50,000 people and found that even after adjusting for other health-related factors, those who consumed small to moderate amounts of alcohol had fewer heart problems.
What Stress Levels Tell Us
Scientists then took it a step further and looked at brain scans from a smaller group of 754 people.
They found that those who drank modest amounts had lower stress signals in a part of their brain called the amygdala, which is responsible for how we react to stress.
Less stress activity in the brain correlated with fewer instances of heart issues. Dr. Ahmed Tawakol, who led the study, explained that an overly stressed amygdala can increase heart rate, blood pressure, and release cells that cause inflammation.
Over time, this can lead to a range of problems like high blood pressure, obesity, diabetes, and heart disease.
Proceed with Caution
It’s important to note that the study isn’t encouraging people to start drinking to boost their heart health. Instead, it aims to understand the benefits and explore other ways to achieve them without alcohol’s downsides.
Because while a modest amount might help your heart, any amount of alcohol increases cancer risk. Excessive drinking, more than 14 drinks a week, can also raise heart attack risk and be bad for brain health.
Moreover, the research showed that the heart-protective effects of alcohol were nearly double for people who are frequently stressed, like those with a history of significant anxiety.
However, finding other ways to manage stress can offer similar heart benefits without the risks of alcohol. The team is now looking into how exercise, meditation, and some medications could provide the same heart benefits.
The Big Picture
So, while a little alcohol might not be bad for your heart, and could even be beneficial, it’s not a one-size-fits-all solution.
The researchers’ end goal is to find alternative ways to achieve the same stress-lowering, heart-protecting effects without needing to turn to the bottle.
