Can Coffee Cause Heart Palpitations? What Every Coffee Drinker Should Know

Coffee lovers know the feeling your heart races, skips a beat, or thuds faster than expected after a strong cup. For some, it’s a temporary jolt. For others, it can be unsettling. This leads to a common question: can coffee cause heart palpitations?

At Bazan Coffee, we believe in fueling not only your day but also your knowledge. In this article, we explore the truth about coffee and heart rhythm, using insights from top industry sources like the Specialty Coffee Association (SCA), Coffee Quality Institute (CQI), World Coffee Research, and Barista Hustle plus clinical data from cardiology research.

Introduction: What Are Heart Palpitations?

Heart palpitations are sensations where your heart feels like it's pounding, fluttering, or skipping beats. While usually harmless, they can feel alarming especially if they happen after caffeine intake.

Palpitations are triggered by various factors, including:

• Stress or anxiety
  

• Stimulant use (like caffeine)
  

• Hormonal shifts
  

• Dehydration or electrolyte imbalances

So where does coffee fit in?

Can Coffee Cause Heart Palpitations? The Short Answer

Yes in some people, especially in high doses or under specific conditions, coffee can contribute to heart palpitations. But it's not always the coffee alone that’s to blame.

According to the American Heart Association (AHA) and data reviewed by the SCA Health & Coffee Committee, moderate caffeine intake (up to 400 mg/day) is generally safe for most adults and is not associated with increased risk of cardiac arrhythmias in healthy individuals.

However, individual sensitivity, caffeine source, and brew method can change the equation dramatically.

The Role of Caffeine in Palpitations

1. How Caffeine Stimulates the Heart

Caffeine is a central nervous system stimulant. It works by blocking adenosine receptors, which normally promote relaxation. This causes an increase in:

• Heart rate
  

• Blood pressure
  

• Release of adrenaline (epinephrine)
  

CQI’s 2023 caffeine physiology report notes that caffeine can increase sinus heart rate by 10–20 bpm in some sensitive individuals, especially those who are caffeine-naïve or under stress.

Bazan’s Fine Robusta – Krong Năng, which contains nearly double the caffeine of Arabica (~2.2%), is a bold, energetic choice best suited for those who tolerate caffeine well or consume it alongside food.

2. Caffeine Sensitivity and Genetics

Not everyone metabolizes caffeine the same way. Genetic differences in the CYP1A2 enzyme determine how quickly caffeine is processed.

• Fast metabolizers tolerate more caffeine without issue.
  

• Slow metabolizers may experience anxiety, palpitations, and sleep disturbances even at low doses.
  

World Coffee Research highlights this variation in their coffee and health toolkit, encouraging personalized brew strategies based on individual response.

For those prone to palpitations, Bazan’s Cau Dat Arabica, a low-caffeine, high-elevation Arabica, offers smoother energy with less cardiovascular stimulation.

Supporting Topics: Other Factors Behind the Flutter

Can Coffee Increase Heart Rate?

Yes temporarily. Especially with:

• Espresso shots
  

• High-Robusta blends
  

• Multiple cups in quick succession

However, this effect diminishes over time with regular use, and moderate intake does not elevate long-term resting heart rate, according to Barista Hustle’s caffeine and endurance analysis.

Can Cold Brew Reduce the Risk?

Yes. Cold brew contains less caffeine per ounce and fewer acidic compounds, making it a gentler option for sensitive systems. Bazan recommends cold brewing Cau Dat Arabica or the Special Vietnam Blend for a smoother, heart-friendly experience.

When to Be Cautious With Coffee and Heart Health

You're more likely to experience palpitations from coffee if you:

• Drink it on an empty stomach
  

• Are dehydrated
  

• Consume more than 3 cups/day
  

• Have a history of arrhythmia or anxiety
  

• Use energy drinks or espresso shots in excess
  

SCA’s 2023 Health Consumption Guidelines encourage not exceeding 200 mg of caffeine per sitting and recommend spacing out caffeine intake over several hours.

Best Practices for Avoiding Heart Palpitations

Coffee, the Heart, and the Bigger Picture

Does Coffee Cause Arrhythmias Long-Term?

The latest research suggests no. In fact, coffee may offer protective effects for the cardiovascular system.

A 2022 meta-analysis in the European Journal of Preventive Cardiology found that habitual coffee drinkers had a lower risk of arrhythmia, heart failure, and stroke with optimal benefits seen at 2–3 cups/day.

These benefits are believed to come from:

• Antioxidants like chlorogenic acid
  

• Anti-inflammatory polyphenols
  

• Improved endothelial function

Bazan’s medium-roast profile, especially in the Special Vietnam Blend, helps retain these compounds without overstimulating the nervous system.

Conclusion: Can Coffee Cause Heart Palpitations? Yes But It’s All About Balance

If you’ve ever asked can coffee cause heart palpitations, you’re asking the right question. And the answer is yes for some people, in some situations. But for the majority of healthy coffee lovers, moderate intake especially from clean, specialty-grade coffee is not only safe but may support heart health.

The key is understanding your body, choosing the right beans, and drinking with intention not habit.
