Caffeine is rightfully considered one of the best natural stimulants.
It reduces the feeling of fatigue, increases attention and improves mood.
The main sources of this substance are coffee, tea, mate and chocolate.
Coffee increases anxiety and can cause a panic attack. As with many other symptoms, it all depends on volume.
Caffeine in large quantities, whether it comes from coffee, green tea or cola, can cause anxiety, muscle tremors, rapid heartbeat, and stomach upset.
Since caffeine blocks the action of adenosine, the body simultaneously stimulates the production of action hormones - adrenaline and cortisol.
The more cortisol in the body, the worse we react to caffeine.
So you may want to drink another cup, but the caffeine will increase your cortisol levels.
A study published in March 2019 in the American Journal of Clinical Nutrition suggests that drinking six or more cups of coffee per day may increase the risk of cardiovascular disease by up to 22%.
