Caffeine and Its Effects on the Heart
Caffeine is a substance that is found in coffee, tea and cola.
It is considered to be a "psychoactive drug" which means it makes the mind alert and awake.
It is extracted from the seeds and leaves of various types of plants.
Consuming any product or plant that contains caffeine has different effects on different things, including the heart rate.
Features After consumption, the caffeine enters the blood stream through the small intestine.
The central nervous system is then stimulated by it from the blood stream.
It also stimulates the heart's cell receptor, which in turn increases the heart rate and speeds up the blood flow.
This increased activity also results in the build up of blood sugar, body temperature and urine production.
Function When caffeine stimulates the heart cell receptors, causing faster heartbeat, it also blocks the phosphodiesterase enzyme, which keeps the heart rate normal, along with the cyclic AMP enzyme.
Time Frame Within 15 minutes, the effects of caffeine consumption can already be noticed and would take approximately six hours before it wanes.
It is not stored in your body, instead, it is excreted through urination.
According to a study from the University of Michigan, each person has different sensitivity to this substance.
However, one thing is common among all, which is, that it increases the heart rate by 3 beats per minute.
