Many people experience heart palpitations, a pounding heartbeat, or hand tremors after drinking tea—whether Thai tea, green tea, or milk tea. Most cases relate to caffeine and may indicate health issues that should not be overlooked.
The cause of palpitations after tea consumption is caffeine, a nervous system stimulant found in tea leaves that can increase heart rate, cause hand tremors, or feelings of restlessness, especially in those sensitive to caffeine.
Five factors that can cause palpitations from tea even when not drinking much:
Drinking overly strong tea leads to high caffeine intake.
Consuming multiple cups a day may prevent the body from fully clearing caffeine from previous servings.
Drinking tea together with coffee increases overall caffeine intake.
Lack of rest or stress can make palpitations more likely.
Some people are highly sensitive to caffeine and may experience symptoms from just one cup of tea.
If you experience palpitations after drinking tea, reduce intake, avoid combining with coffee, and ensure adequate rest. If symptoms recur often, monitor closely for signs indicating heart disease risk.
While palpitations after tea usually relate to caffeine, certain abnormal symptoms may signal arrhythmias or heart disease, including:
Palpitations occurring without drinking tea, with unexplained strong or rapid heartbeat.
Frequent irregular heartbeats, feeling skipped beats, racing, or uneven rhythms.
Palpitations that persist long after reducing or stopping caffeine intake.
Palpitations accompanied by easy fatigue, especially during normal activities like walking or climbing stairs.
Palpitations with dizziness or lightheadedness, which may be linked to abnormal heart rhythms.
What you should knowThese symptoms do not always mean heart disease; they can also stem from other conditions such as hyperthyroidism or anemia.
Palpitations after drinking tea are often due to caffeine. Initially, reduce intake and observe your symptoms. If palpitations continue frequently without tea consumption or are accompanied by fatigue and dizziness, consult a doctor for proper diagnosis.
