How Caffeine Works in Your Body

Caffeine is quickly absorbed into the bloodstream and spreads throughout the body, even crossing into breast milk and the placenta. Its stimulating effects are due to increased heart and nerve activity, and its impact on calcium within cells. These actions can affect heart dynamics and blood pressure.

Caffeine's Influence on Heart Rhythms

Caffeine doesn't usually cause arrhythmias at typical consumption levels, but individuals sensitive to caffeine might experience palpitations. Most studies show no increased risk of arrhythmias, and some even suggest caffeine might have protective effects against certain heart conditions.
