Neurostimulants, a category of substances that enhance the nervous system's activity and alertness, serve various purposes, including therapeutic and recreational use, exerting a spectrum of effects on the body and brain. Among these neurostimulants, caffeine stands as one of the most commonly consumed, naturally present in coffee, tea, and chocolate. Caffeine functions by obstructing the influence of adenosine, a neurotransmitter that induces drowsiness. Consequently, it heightens alertness and wakefulness. While caffeine is generally considered safe when consumed in moderation, excessive intake can result in adverse side effects like anxiety, insomnia, and increased heart rate.
