Caffeine: The unfiltered truth.

Caffeine, the main component of coffee and energy drinks, is the most widely used psychoactive drug in the world. While caffeine can improve cognitive abilities and alertness, its health risks, especially in energy drinks, have been a cause for concern. However, research suggests that moderate coffee consumption can have various health benefits, such as improved mood, lower risk of depression and Parkinson's disease, and potential heart health benefits. On the other hand, excessive consumption of caffeine, particularly in energy drinks, can lead to adverse effects on health, including increased heart rate and blood pressure. It is recommended to consume caffeine in moderation and consult a doctor if there are any concerns. [Extracted from the article]
