Increased heart rate
Caffeine is a known stimulant, hence why you may feel more awake and alert after drinking your coffee.
However, since it is a stimulant, it can also end up increasing your heart rate, and when consumed in high amounts, it can permanently alert your heartbeat!
Atrial fibrillation, which is the medical name for a heartbeat rhythm that has been altered, has been observed over the years in a high number of young people who have been consuming extremely high doses of caffeinated energy drinks.
What’s more, in a case study, a woman took a high amount of caffeine powder with caffeine tablets in an attempt to leave this plane; the result from this high amount of caffeine ended up being kidney failure, along with a very high heart rate, along with other severe health issues.
Despite the medical papers that prove the fact that caffeine can end up spiking your heart rate, it is not a side effect that ends up occurring in all people who end up consuming a lot of caffeine.
It can also happen that people who are known to have heart issues end up being able to tolerate a high amount of caffeine without issue, while otherwise healthy people can develop these side effects.
No matter if you have any known heart issues, or if you have noticed that your heart has been beating irregularly after you drink any beverage containing caffeine, it is a good idea to cut down on the amount of caffeine you consume.
