Ever wondered how long that morning coffee *really* sticks around? You're not alone! The duration of caffeine's effects varies wildly from person to person, but a general estimate is that it has a half-life of about 5 hours. This means that after 5 hours, half of the caffeine you consumed is still active in your system.
Several factors influence this, including genetics, body weight, and even your tolerance. Some people metabolize caffeine much faster than others, leading to a shorter, less intense buzz. Others might find themselves wide awake hours after their last cup.
Age also plays a role; older adults often process caffeine more slowly. Similarly, certain medications and liver conditions can impact caffeine metabolism. So, while that afternoon latte might seem harmless, be mindful of your individual sensitivity and how long caffeine lingers for you. Pay attention to your sleep patterns and adjust your caffeine intake accordingly for optimal zzz's!
