Caffeine: What You Should Know

Understanding Caffeine

Caffeine is a widely recognized stimulant and can be quite addictive. It's commonly found in our everyday beverages like tea and coffee. You can also find it in smaller quantities in chocolate and cola drinks. For instance, a 100 ml cup of tea contains around 11 mg of caffeine, while a similar-sized cup of coffee packs about 41 mg—roughly equivalent to the caffeine in four cups of tea.

Caffeine primarily affects our central nervous system by speeding up nerve responses to the brain. This has spurred a lot of discussions regarding its benefits and drawbacks. The consensus seems to be that moderation is key—too much of anything, even something as seemingly harmless as coffee, can lead to negative outcomes.
