Coffe and tea are one of the most loved beverages in the world. Often people are advised to avoid coffee due to the heart conditions. Now, according to a study, drinking up to three cups of coffee or tea a day is safe as well as reduce irregular heartbeat and stroke risk.

As per the research, a single cup of coffee contains about 95 mg of caffeine. It acts as a stimulant to the central nervous system and works to block the effects of adenosin,  chemical that causes atrial fibrillation (AFib). AFib is the most common heart rhythm disorder, causes the heart to beat rapidly and skip beats, and if left untreated, can cause strokes.

The findings of the research suggest that caffeine intake of up to 300 mg per day may be safe for arrhythmic patients.

lead author Peter Kistler, Director at Melbourne's Alfred Hospital said that there is a public perception, often based on anecdotal experience, that caffeine is a common acute trigger for heart rhythm problems. Ut caffeinated beverages such as coffee and tea have long-term anti-arrhythmic properties mediated by antioxidant effects and antagonism of adenosine.
