Decreasing heart rate after consuming caffeine

In this study, we sought to answer the question “how can we decrease heart rate after drinking caffeine?” To find ways to help/boost the heart rate recovery after drinking caffeine. Hypotheses tested are taking a walk (1), deep breathing (2), and drinking water (3). After testing each hypothesis, we found that all methods result in a decrease in heart rate. However, only deep breathing was able to reduce heart rate while also decreasing side effects (dizziness, lightheadedness, etc). People who drank caffeine and faced either heart rate increase or side effects (dizziness/ lightheadedness, etc) could perform the methods on themselves to prevent either heart rate increase or side effects. Results of each method were different, and the recommended method is taking a walk since after applying, it decreased heart rate without side effects.
