Coffee is not harmful to people with irregular heart rhythms, in fact, it has been linked to improving your brain functions. A new research claims that coffee may actually be good for you heart.


Caffeine can have both positive and negative health effects. It works by adding more energy to the inside of your cells. Many of us believe that it can harm our heart’s electrical system as it is known to make the heart beat faster.

Australian researchers have reported that that morning cup of coffee does not increase the likelihood of irregular heart rhythms, but may diminish arrhythmia frequency. The new research was published in the Journal of the American College of Cardiology.

According to the Center for Disease Control and Prevention, About nine percent of Americans older than 65 years-old have Atrial Fibrillation – irregular heartbeat. Researchers believe that coffee and tea have kind of properties that protect against abnormal rhythm.

However, it is required to know that some patients with atrial fibrillation have a negative association with caffeine.

Moreover, the researchers suggest that some energy drinks are risky as they may cause life-threatening rhythms and even blood clots.

“Large-scale population-based studies and randomized controlled trials suggest coffee and tea are safe and may even reduce the incidence of arrhythmia. Although there is no clearly defined threshold for caffeine harm, a regular intake of up to 300 mg/day appears to be safe and may even be protective against heart rhythm disorders,” Peter Kistler, MBBS, Ph.D., of the Alfred Heart Centre in Melbourne, and colleagues concluded.
