caffeine effects

Caffeine is a natural stimulant found in coffee, tea, and other beverages. It works by blocking adenosine, a brain chemical that makes you feel tired, leading to increased alertness and reduced fatigue. It can enhance focus, improve mood, and boost physical performance. However, too much caffeine can cause side effects like jitters, anxiety, or sleeplessness. Sensitivity to caffeine varies among individuals, so while some can enjoy its benefits without issues, others may experience discomfort even with small amounts. Moderation is key to maximizing its positive effects while minimizing potential downsides.
