We all love that caffeine kick, whether it's from coffee, tea, or an energy drink. But have you ever wondered, "How long does caffeine stay in your system?" The answer, like a good espresso, is complex!
Generally, caffeine has a half-life of about 5 hours. This means it takes approximately 5 hours for your body to eliminate half of the caffeine you've consumed. However, the effects can linger longer. Factors like your age, genetics, liver function, and even other medications can influence how quickly you metabolize caffeine.
So, if you have a cup of coffee at 3 PM containing 100mg of caffeine, around 50mg will still be in your system around 8 PM. That leftover caffeine could interfere with your sleep! Therefore, be mindful of your caffeine intake, especially later in the day, to ensure a restful night. Listen to your body and adjust your consumption accordingly. Sweet dreams (eventually)!
