Caffeine acts as a stimulant for the central nervous system, which can result in a faster heart rate and potential palpitations. Individual responses to caffeine can widely differ, with some people experiencing symptoms after just a single cup. Factors such as stress and sleep deprivation can further amplify palpitations, warranting attention for possible health concerns. Immediate medical help should be sought if symptoms like chest pain or dizziness arise.
