1. Heart
Caffeine acts on the heart in two ways: in addition to affecting the brain center that regulates the cardiovascular system, caffeine also acts directly on the heart. High doses of caffeine can increase the heartbeat of people who do not tolerate caffeine by 10 to 20 beats per minute and may cause temporary arrhythmias in some people. Therefore, moderate consumption of drinks containing caffeine (an average of up to 500 mg per day) does not significantly increase the risk of heart disease, but exceeding this dose may increase the risk of myocardial infarction.

It is a common occurrence for many people to go to the toilet after drinking coffee in the morning. This is because caffeine affects adenosine receptors in the kidneys, acting like diuretics. Caffeine may also slow the brain's release of an antidiuretic hormone that reduces urine production.
