Faster Heart Rate
In cases of too much caffeine intake, most people will experience an increase in heart rate, the degree of which differs among individuals. The increase depends on various factors, including the amount of caffeine consumed, consumption frequency, body weight, and physiology, to name a few. Therefore, sensitivity to caffeine is unique to each individual.
While moderate amounts of caffeine appear safe for most people, there is some concern that too much caffeine may be bad for heart health. This is because high doses of caffeine can cause a short-term increase in blood pressure. However, whether this effect leads to long-term problems such as high blood pressure or heart disease is unclear.
More research is needed before any definitive conclusions can be drawn. In general, it is best to moderate the intake of caffeinated beverages for people concerned about their heart health. For people who regularly consume caffeinated beverages and experience faster heart rates, it is best to cut back on caffeine intake or switch to decaf versions.
