A recent study involving nearly 600,000 individuals across 19 countries indicates that indulging in an additional drink each week may reduce your lifespan by approximately 30 minutes. Conducted by researchers at the University of Cambridge, the findings suggest that exceeding recommended alcohol consumption can lead to significant heart-related health issues, consequently impacting life expectancy. For some individuals, this dangerous threshold is even less than one drink per day.
Excessive alcohol intake is linked to a higher likelihood of serious conditions such as stroke, heart failure, and fatal aneurysms, according to the findings published in The Lancet this week. Understanding safe consumption levels is crucial for enjoying alcohol responsibly. The study referenced the UK’s alcohol guidelines, which were updated in 2016 to recommend a maximum of 14 units of alcohol weekly—equivalent to about six pints of beer or six glasses of wine.
To simplify alcohol unit calculations, a standard glass of red wine typically contains two units, while white wine may have three. Beer varies from two to three units, depending on its alcohol content. The researchers established that the upper limit for safe weekly consumption is around five drinks, translating to over five UK pints or around 95 ounces of beer with 4% alcohol by volume, or five 175ml glasses of wine with 13% alcohol by volume. Regularly exceeding these recommendations could lead to health complications.
The study found that consuming 10 or more drinks each week could result in a loss of one to two years of life, while having 18 drinks could reduce lifespan by four to five years. This research serves as an important wakeup call for drinkers globally, as alcohol consumption guidelines vary across countries. “This is a serious wakeup call for many nations,” noted Dr. Peter Collins, a medical advisor at the Heart Health Organization, which supported the study.
In the United States, current guidelines define moderate drinking as up to one drink per day for women and up to two for men. “This compelling study highlights the need for countries with higher drinking recommendations to reassess their guidelines,” remarked Sarah Thompson from the Heart Health Organization. “Alcohol guidelines should be viewed as limits rather than goals, encouraging individuals to aim below these thresholds.”
The encouraging takeaway is that cutting back on alcohol doesn’t mean giving it up entirely. “The central message of this research is that reducing alcohol intake can enhance longevity and decrease the risk of cardiovascular diseases,” explained Dr. Emily Grant, the lead investigator of the study.
