How long does it take for a heart to recover after drinking caffeine?

The heart's response to caffeine can vary significantly among individuals, but generally, its effects are felt within 15 minutes and can last for several hours. After consuming caffeine, heart rate and blood pressure may temporarily increase, but most healthy individuals typically return to baseline levels within a few hours after the effects wear off. Full recovery can take longer, depending on factors like individual sensitivity, the amount of caffeine consumed, and overall health.
