Light drinking can reduce the risk of a heart attack.
Drinking can reduce the chance of a heart attack
A new study suggests that a daily alcoholic tipple lowers stress levels in the brain and therefore slashes the prospect of cardiovascular events.
Experts from Massachusetts General Hospital in the United States discovered that the part of the brain that responds to threats - the amygdala - displays fewer stress signals in those who drink in moderation compared to teetotallers.
Alcohol is known to reduce the amygdala's reactions to possible threats while drinking but the research is the first to suggest booze has long-term effects on heart health.
Cardiologist Ahmed Tawakol, who led the study, said: "When the amygdala is too alert and vigilant, the sympathetic nervous system is heightened, which drives up blood pressure and increases heart rate.
"If the stress is chronic, the result is hypertension, increased inflammation, and a substantial risk of obesity, diabetes, and cardiovascular disease."
