Caffeine is a natural stimulant found in coffee, tea, and many energy drinks. It works by blocking adenosine, a brain chemical that promotes sleep, which helps increase alertness and reduce fatigue. In moderate amounts, caffeine can enhance focus, improve mood, and boost physical performance. However, consuming too much caffeine can lead to negative effects such as anxiety, jitteriness, and difficulty sleeping.
Individual sensitivity to caffeine varies, so it’s important to know your limits. Excessive caffeine intake may cause increased heart rate, digestive issues, and dependence. To enjoy caffeine’s benefits without adverse effects, try to consume it earlier in the day and avoid large amounts. Balancing caffeine intake with adequate hydration and healthy sleep habits supports overall well-being. Shutdown123
