How Much Caffeine Is Too Much<\/figcaption><\/figure>\n\n\n\n

What Is Caffeine & How Does It Work?<\/strong><\/h2>\n\n\n\n

Caffeine is a natural stimulant found in coffee beans<\/a>, tea leaves, cacao, and some medications. It works by\u00a0blocking adenosine<\/strong>, a brain chemical that makes you feel tired. At the same time, it triggers the release of\u00a0adrenaline<\/strong>\u2014giving you that familiar burst of energy.<\/p>\n\n\n\n

Short-Term Benefits of Caffeine<\/strong><\/h3>\n\n\n\n

\u2714\u00a0Increased alertness<\/strong>\u00a0\u2013 Helps you feel more awake and focused.
\u2714\u00a0Better concentration<\/strong>\u00a0\u2013 Enhances mental performance for tasks like studying or driving.
\u2714\u00a0Temporary energy boost<\/a><\/strong>\u00a0\u2013 Fights fatigue, especially during slumps.<\/p>\n\n\n\n

But these effects don\u2019t last forever. After 4\u20136 hours<\/strong>, caffeine wears off, often leading to a “crash” where you feel even more tired than before.<\/p>\n\n\n\n

How Long Does Caffeine Stay in Your System?<\/strong><\/h3>\n\n\n\n
