Caffeine
Caffeine increases alertness by blocking adenosine, a brain chemical that promotes relaxation. However, in sensitive individuals or at high doses, this can lead to increased heart rate, nervousness, and anxiety. If you notice heightened feelings of anxiety after your caffeine fix, it might be time to reassess your intake.

While caffeine provides a temporary energy boost, it can lead to significant energy crashes as its effects wear off. This cycle can result in dependency, where more caffeine is needed to combat fatigue, perpetuating the problem.
